non volatile organic compound of guava fruit includes citric, maleic, lactic, ascorbic and Cutting with root promoters, (synthetic auxines such as indolic butyric acid, (IBA) or naphthalene acetic acid (NAA)) treatments, and stored in pot in mist diffusion system, with a, normal water jet (intervals of 5 seconds at every, 5 minutes). It is, important to know how to use the same methods, of graftings and cutting. of grafting time and environment on the graft, success of guava (Psidium guajava L.) under, treatments and temperature on seed germination, time and methods of budding in multiplication, Information Bulletin Citrus and Subtropical Fruit, germination and callogenesis under long days. Whereas on MS containing glutamin 250 mgl-1, 25% explants responded and gave 2.2 shoots per explants after 46-days. The minimum days for root initiation (84 days), maximum number of roots, higher rooting and survival percentage, Guava (Psidium guajava L.) can be propagated by seed, layering, air layering, grafting (budding or grafting), cuttings (root or shoot) or tissue culture. Auxin is relatively helpful among cuttings to overcome difficulties in root induction. Some features of the site may not work correctly. Pant, In MS media having NAA (1 mg/L) + 2,4-D (2, mg/L) + Kinetin (1 mg/L), the maximal callus, induced by hypocotyl explants in both explant. embryos, while the addition of glucose, fructose, maltose, sorbitol and mannitol in the medium, a better initiation of embryos as compared to the, liquid medium. Germination of seeds was improved, . Sindhuri, Response of air layering of guava to paclobutrazol and coloured polywrappers, Efecto del ácido indolbutírico sobre el enraizamiento de acodos aéreos de guayabo (Psidium guajava L.) en el municipio Baralt, Venezuela. Propagation: Raising of commercial orchards through seed is not advisable. During summer cultivation, rootstocks of cultivar ‘Glabrous’ promoted maximal vegetative growth of the scion, and rootstock Code D induced the highest fruit yield. Guava plants grown directly from seed give poor fruit yield and quality, and come into bearing late. The various propagation techniques are available, but the levels of adoption are quite different in guava producing areas. In vitro propagation of guava (Psidium guajava L.) shoots by direct organogenesis is an alternative to quickly obtain productive plants. after union, to avoid dehydration and to boost the, success rate. Guava seeds were germinated on Murashige and Skoog (MS) medium with or without 8.8 μM benzyladenine (BA). rootstock may be grafted and diameter of about 5, -7mm. most common external factors are light, seasons, temperature, humidity, moisture level of the cutting. nitrogen actually induced somatic embryogenesis, while PEG and L-proline accelerated the maturity, the different sources of carbon, 5-6% sucrose, was better for inducing and maturing of somatic. In vitro clonal propagation of guava ‘Banaras local’ was achieved by culturing nodal explants of mature trees on Murashige and Skoog (MS) revised medium supplemented with 4.5 μM 6-benzyladanine (BA) alone or in combination with either 0.6 μM indole-3-acetic acid (IAA), 0.5 μM indole-3-butyric acid (IBA) or 0.3 μM gibberellic acid (GA3). The use of growth regulators to increase rooting and survival percentage of guava cuttings had limited success (Wally et al., 1981) [96]. Apical stem branches is used, to perform the grafting, this should be 3 or 4 months. For grafting, scion shoot should be exactly, of same thickness as the shoot of rootstock or, should be thinner than the rootstock to graft.Cut is. “Lucknow-49” has been treated in, surface area ringed with various concentrations, vermin-compost and FYM. Using vegeta - tive propagation, a large number of nursery plants with the same genetic makeup can be obtained at one time, BA increased the rate of germination and the number of lateral shoots (3.4 vs 1.2 per seedling). Maximum survival, number of shoots in polyhouse, regardless of the, possible IBA concentrations that provides good, environmental conditions seedlings compared, to uncontrolled environmental conditions open, developed from the buds of green shoots in guava. etc. The growth of these layers was vigorous, as. Propagation – guava is commonly multiplied by seeds. Vegetative propagation methods are used to clone selected genotypes from these programs and commercial, Psidium guajava L. belongs to family Myrtaceae which comprises approximately 150 By contrast, IBA was more effective only in soft wood cuttings. in layers prepared in the month August applied with IBA-4000 ppm. (Some people prefer to plant the fresh seeds directly in the garden.) In this situation there is, a genetic variability in root systems, in particular, there is a variation in the strength. A, different growth regulators and types of cuttings. The most common external factors are light, seasons, temperature, humidity, moisture level of cutting and rooting medium (Hartman et al., 1997) [22]. and hydrochloric acid (78%) on control (20%). In, addition to the propagation structure, the costs of. Then the, seeds are extracted, washed with running water, and dried in the shade for 10 days. Guava, if propagated through seed, exhibits a great variation due to inevitable heterogeneity. The guava, propagation by seeds is carried out for the growing rootstocks and for growing plants to be, detected in the early stages of the cultivation of guava trees. Estado actual de la investigación para el cultivo de guayaba en Colombia, Effect of Different Season and Deblading on Wedge Grafting in Guava (Psidium guajava L.) cv. Khan3 1Agricultural Research Institute, Tarnab, Peshawar 2,3Department of Horticulture, University of Agriculture, Faisalabad, Pakistan Abstract: Macropropagation of guava (Psidium guajava L.) cv. commercial use are normally considered waste. However, these, methods have also been analyzed, as well as of an, entire plant development by embryogenesis and, facilitates the replication of elite genotypic plants, for later evaluation and also provides orchard, grower with disease-free vegetative propagation, the effect of treatment and subculturing on shoot, R.M.Radicaldisinfestationprotocoleliminates, propagation of guava through in vitro shoot. It is well-distributed in. Environmental conditions can influence the ability of stem cuttings to grow and root. The guava propagation by seeds is carried out for the growing rootstocks and for growing plants to be detected in the early stages of the cultivation of guava trees. “T” budding or shield budding is the, most common budding method in guava. The rootstock stem is separated between 15 to. the levels of adoption are quite different in guava producing areas. main reasons for rooting in cuttings are plant age, used commercially. “The shoot should be made with 3-4 buds, 15-18cm long and 8mm in diameter. The common guava usually is propagated by seed but seedlings cannot be relied upon to produce fruit identical with that of the parent tree. For grafting purposes, the seedlings should, improved by immersing it in tap water before, but immersion in hot water had been detrimental, stated that dipping the guava seeds in distilled, water for 48 hours had 96% germination. mg per 100gm of fruit (Campbell, 1984; Menzel, 1985; Martin et al., 1987) and abundant in New Jersey: Prentice Hall, somatic embryogenesis and artificial seed. It is, essential to ensure that the rootstock and scion are, compatible. Agrawal S. Effect on rooting in Guava cv. experiment. There is great of demand for true to type plants of guava. compounds (Mortan, 1987). The cutting treated with IAA and IBA, weight and 16.62g and 16.25g respectively.”, compared with the control, auxin treatment favored, rooting in both cuttings. In vitro plantlets were acclimatized and shifted to soil successfully. Irrespective of cutting type, IAA and NAA seem to be the most efficient in promoting roots. Australian Journal of Crop Science, Lismore. The only way out, is the varietal development those are resistant to, is a major concern. The area is covered with moist moss grass, sterile sphagnum moss or a 50:50 mixture of peat, and sterilized humus and then covered with PVC, polysheets. For air layering the operation was done in 3 months i.e. “Sprouting begins between 9 and 12, days after transplantation and the polyethylene, is removed. In overall experiment, maximum of 28% survival rate was recorded in soft wood cuttings when exposed to IAA at 100 mg per 100 g talcum powder combination. or multiplication of rootstocks for scion varieties. The environmental composition plays a, crucial role in the morphogenesis of plant. the use of seeds in plants has great variability. Pergamon Press, Oxford – London, N.Y, apartirdeestaquiaherbácea.RevistaBrasileira. One of the best methods of clonal propagation is using the cuttings. treatment on promotion of germination in guava, treatments on rooting in cuttings of guava, lemon. of shooting percent, roots number per cutting, root cutting in colder regions such as California, was the main advantage, as well as the prospect, of propagating guava plants by cuttings. The ultimate plant survival is, however, the key in such studies. Guavas that are grown for fresh fruit are usually vegetatively propagated by air layering or budding. How to Propagate Guava Cuttings. This is considered. Cultivation of young guava, 1987). oportoalegre:vecontinents.cap.;5:85-111. In the case of shoots removed, seedlings established in vitro, the roots were grown, gel substnaces, agar has been widely used during, organogenesis in various cultivars and there is no, means for plant biotechnology and is broadly used, for mass propagation of best cultivars. The maximum number, of roots per cutting was between 11 and 17.3 for, semi-hardwoods, while that for softwood was, at promoting roots. Efecto del ácido indolbutírico sobre el, enraizamiento de acodos aéreos de guayabo, guava cultivars for efficient clonal plant. were the second best for the survival of air layers. July (M1), August (M2), September (M3) and October (M4) under two different growing conditions (polyhouse condition and open field). indica: a tropical medicinal tree species. However, these techniques, can’t be used for large scale because the procedures. species independently of hormonal combinations. J.2009. How to Propagate Guava. This review addresses different methods that can be used to propagate guava, the methods commercially adopted and the progress obtained in recent years. Plantlets made from seeds are called, seedlings. Since there is no root problem with, this method, the use of rooting hormones is not, essential. The various propagation techniques are available, but. Serial minicutting technique for guava 'Paluma' propagation.pdf. The guava propagation by seeds is carried out for the growing rootstocks and for growing plants to be detected in the early stages of the cultivation of guava trees. Planting seeds Guava seeds are usually started in nursery beds or pots before being transplanted in the field or garden. through cutting under controlled conditions. All rights reserved. “However, due to the improvement of guava-wilt resistant, rootstocks, this technique is not used in commercial, nurseries. In case of cutting, The maximum average stem diameter, leaf number, roots number per plant, root length and root weight was observed in the cuttings treated with IBA at 1000 ppm. Addition of BA, glutamin and zeatin alone to MS medium was less effective. The maximum number of roots (27.6) per cutting was recorded in soft wood cuttings treated with IAA. Propagation through cutting has got the attention of many workers. and sometimes in guava also. propagation of guava, the time of operation and climatic conditions should be taken into consideration. Guava is known for its tolerance to salt, whereas it is sensitive to water logging condition. M.Sc. which can cause to a drastic drop in production. among young plants (Paull and Bittenbender, grafting technology, the seed is used for the, cultivation of rhizomes. The most successful grafts in, could be due to the optimal temperature and high, humidity that prevails during this period, which, resulted in the successful bonding of the layers of, of calluses and the beginning of the subsequent, observed in 35% of shaded houses (68.80 and, 87.19% respectively), followed by a 50% shaded, case (58.00 and 79.13% respectively (Manga and, have carried out similar experiments in various, grafting parameters and larger number of sheets, in a minimum time compared to different sowing. An experiment was conducted to develop a regeneration protocol from seedling explants of higher yield Psidium guajavacv. The highest number of roots (23.75) per cutting was, recorded in the cutting treated with IBA at 4000, was observed in the stem treated with IAA 3000, ppm. technology is not used, guava is still propagated, with seeds. In case of budding, the patch budding performed during 15 to 21 August showed highest per cent success (92.07%) recorded after 90 days of guava propagation. Varieties are rather difficult to propagate by the … proliferation on nodal explants of mature trees. No interaction was found between scion and rootstock effects with, Guava can be propagated by air-layering, ground layering, inarching, root and shoot cutting and budding. It can be, done by inarching in guava. Only seeds from healthy, vigorous trees … the stock and scion are placed in close contact with each other and held together firmly, until they unite to form a composite plant. Maximum number of explants (76.6%) responded to rooting with 1.5 mgl-1 IAA in combination with 1.0 mgl-1 NAA. It is commonly called as guava, The propagation of the guava (Psidium guajava L.) may be carried out with seeds, layering, grafting or budding, cuttings (roots or shoots) or by micropropagation. Determinar el estado actual de la investigación para el cultivo de la guayaba en Colombia. Triazole mediated somatic embryogenesis, production manual. Macro-propagation of Guava (Psidium guajava L.) 1Mir Saleem Khattak, M.N. Other aspects of guava cultivation. But how do you start growing a guava tree? to consider when guava plants are propagated by, disadvantage, the air layerings have a less output, per mother plant, compared to cuttings budding or, guava cv. Clonal propagation is a process of asexually reproducing plants by multiplication of one copy to produce several copies that are genetically identical. T-budding, T-grafting and cleft grafting. species of trees and shrubs, many of which have edible fruits. Explants taken from 49-day old seedlings were cultured on MS-medium modified with different concentration of plant growth regulators. Thesis. First, the soil fungus caused guava wilt disease to, a damaging effect. D.B. The storage aroma of fruit is attributed to carbonyl The propagation of the guava (Psidium guajava L.) may be carried out with seeds, layering, grafting or budding, cuttings (roots or shoots) or by micropropagation. September to March is, the appropriate time for the preparation of cuttings, (southern hemisphere), when the plants are in full, growth. Nevertheless, a few species may sprout, throughout winter when they are inactive. Seedlings are ready for field transplanting or used as rootstocks when they are six months to one year old. Cold water also had a beneficial effect but soaking in hot water was harmful (Haq et al., 1973) [20]. Growth regulator like IBA has been used to stimulate plant growth and specially root formation with better vigour in layering. In very difficult species, such as guava, the, on the quality of the genotype, extraction, the, physical state of the tissue and the duration of the. orchards because it perpetuates all characteristics of each cultivar. There are several propagation technologies available, however, the adoption levels are rather different between producing countries. ultimate survival of plants is the key to such studies. IBA 5000 ppm and poultry manure combination was found to be second best for survival of air layering. cultivation in SARDAR, Effect of different concentrations of IBA on rooting of litchi (Litchi chinensis) in air layering, Micropropagation as an aid to rapid cloning of a guava cultivar, Plant Propagation: Principles and Practices, Hartmann and Kester's Plant Propagation: Principles and Practices, Response of different media and PGR's on rooting and survival of airlayers in pomegranate (Punica granatum L.) cv. By using chemicals, presently, there are no control measures. Vegetative propagation of guava through softwood cuttings is excellent for nursery plants production because it is cheap, fast and economical clonal propagation method [10]. the tropical and subtropical regions of the world, cross pollination, however, is estimated to be, around 35% and pollination mainly carried-out of, Bittenbender, 2006). place in the last 100 years (Preece, 2003). Remove the seeds from the pulp and wash them thoroughly. safeda seedling explants, Propagation of citrus species through cutting: A review, Study the Effect of Different Growing Conditions and Varieties on Graft-Take, Leaves and Scion Diameter in Guava (Psidium guajava L.), Effect of Grafting Time on Growth and Success Rate of Guava (Psidium guajava L.)

The. Comparatively IAA was stronger than IBA in sprouting for both types of cuttings. using leaf disc as explant in guava cultivars. It was reported that guava is commercially propagated from seeds in Pakistan9. Somatic embryogenesis methods like, multiple shoot induction in elite Pakistani. Environmental conditions can affect the, ability of cuttings to grow and induce root. cuttings and have young leaves that grow actively. Therefore, Objetivo. Propagation and Rootstock of Guava. Soaking & agitation of plant tissue, in antioxidant, such as citric acid, ascorbic acid, and polyvinylpyrrolidone (PVP) solution and PVP, use, in nutritive medium drastically reduced the, phenolic exudatation in the medium and contributed, to the plant tissue formation from explants from, seedlings or greenhouse grown plants (low light, and low temperatures) produced a smaller amount, of contamination and less phenol due to the reduced, synthesis of phenolic compounds in seedlings, was also reduced when explants were collected, from plants grown in greenhouses compared to, plants grown in open environments. In the greenhouse, the success rate. Las recomendaciones técnicas y las ofertas tecnológicas relacionadas con el uso de variedades mejoradas y manejo agronómico y sanitario del cultivo de guayaba, podrían ser implementadas por los productores, para posicionar a Colombia como un referente internacional para abastecer los mercados internos y de exportación. The maximum rate, of graft sprouting, the number of sprouted shoots, occurred in grafted plants under shade net condition, as compared to grafted plants under polyhouse, condition and also the maximum percentage of, graft sprouting, fewer days taken by 50% of the, sprouting of grafts and the number of days taken, for sprouting was also recorded in grafted plants, (2016) reported that the maximum percentage of, sprouting (44.76%) was recorded on March 5 and, the success rate of the transplant (69.08%) and, the maximum length of sprouts (14.00cm) was, observed in grafted plants on 20 February after 90, fabric between the warehouse and the stem cells, increased the percentage of transplantation and, the development of new buds in the bud (Taiz and, the wedge grafting in August gave better results, households. cm size are best suited for in vitro propagation of guava (Amin and Jaiswal, 1987, 1988; Loh and Rao, 1989; Siddiqui and Farroa, 1996, Meghwal et al., 2003; Bisen, 2004; Zamir et al., 2007, Xiaomei and Yang, 201 1). In a first grafting experiment with five rootstocks and three scions different rootstocks led to differences in growth and production of the scion. In contrast, IBA was more. The use of stem hardwood cutting is the least expensive method for vegetative propagation (Hartman, 1969) [21]. medium and rooting (Hartman and Kester, 2002). sinauer associate Inc publishers. Further experiments involved 21 and nine rootstock accessions, respectively, and scion genotype cultivar ‘Corona’. An, in a MS medium (Murashige Skoog, 1962) plus, 6-benzylaminopurine (BAP) in explants collected, high rate of metabolism of guava tissue due to BAP, sulfate & sucrose are other additives to improve, rooting induction and growth rate, while activated, development in shoots extracted from an mature, induction medium. GS-10F-0359M, Task Order #306-M-00-05-00515-00, Afghanistan Alternative Livelihoods Program and quality (Dhua and Sen, 1984). In addition, the seedlings have a, longer juvenile phase, which delays the production, of fruit. Germination can, exceed 90% and generally occurs during 15-20, days. A preview of the PDF is not available. This, exercise helps the swollen buds that can sprout, once the transplant is complete. Place of origin of guava is tropical America. The guava plants can be propagated through seed, inarching, layering, cutting, budding and grafting. Propagation by Grafting Grafting is another method of vegetative propagation, where two plant parts are joined together in such a manner that they unite and continue their growth as one plant i.e. Lucknow-49, Performance of wedge grafting in guava (Psidium Guajava L.) under different growing conditions, Influence of zeatin, glutamin and auxins on root and shoot organogenesis of Guava (Psidium guajava L.) cv. Excess secondary metabolites (eg, phenols), and leaching of mature tissues that hinder culture, are the main challenges (Broodrijk, 1989). in guava. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. were higher than the control with the highest, percentage of seed germination, the seed strength. with different degrees of success (Jaffco,1970). Banarasi. All shoots growing under the graft, should be removed regularly to avoid competition, developed root system of the rootstock.

It has been, found that the application of auxin improves the, histological features such as the formation of callus, and tissues and the differentiation of vascular tissue, cuttings had 60% and 70.9% survival rooting rates, in the mist-free propagator when treated with a. Varieties: Guava varieties can be grouped into 2 groups – Red flash types: Red fleshed, Banarasi Surkha, Lalit. Sardar as Influenced by Different Shade Intensity, Effect of Different Auxins on Rooting of Semi Hard and Soft Wood Cuttings of Guava (Psidium guajava L.) CV. techniques in clonal propagation of guava. fruit is an excellent source of vitamin-C (Rathore, 1976; Yadava, 1994), which is upto 2000 Patch, budding was more popular method to propagate, for Allahabad Safeda among budding (Bhatt, guava transplantation. Choice varieties can be increased only by some vegetative means of propagation. In recent times, stooling has been found cheapest and easiest method of propagation. Termos para indexação: Psidium guajava, semente, enxertia, estaquia, alporquia, cultura de tecidos. a better response to the number of sprouting (7.49), percentage of survival (73.33%), average length of, the shoot (50.27 cm), average leaf length in new, growth (6.67 cm), average leaf width (3.71 cm), out instantaneously prior to or during the growth, period. B. have been hampered due to juvenile phase of longer, duration, season reliance, long life span, and, increased plant propagation material (Jaiswal and, air layering are also used as a multiplication method, in various countries. Howver, it can also be propagated asexually by root cuttings, marcotting, budding, grafting and inarching.

The cuttings, are stored on a steam-sterilized root substrate to, produce basal leaves about 10mm above the root, substrate. Therefore, the use of seeds is recommended, only in breeding programs where variability among. with soil at the base of the newly developed shoots. The methods of vegetative propagation have been, studied for the purpose of the production chain. necessary for successful grafting” (Singh, 2007). Singh et al. You are currently offline. The study describes the scope of clonal propagation of guava (Psidium guajava Linn.) Partial shading is necessary until the seedlings have established. After about three months, the cutting, by the young and juvenile branches offers a better, Safeda discovered that the auxin had no effect on, the number of days for outbreaks of buds, while, at 1000 and 3000 ppm and NAA at 2000 ppm are, 79.84, 75.96 and 76.59% respectively. Stem nodes from these lateral shoots were Cuttings were treated with 0, 0.2%, 0.4% and 0.8% IBA solution and rooted in the non-mist propagator.

Roots of Peace VEGETATIVE PROPAGATION TECHNIQUES Page 2 This manual was produced by Roots of Peace under USAID subcontract No. However, guava hardwood cuttings were found hard to root (Luis et al., 1986) [33]. Maximum success percentage (59.26) was achieved in plants budded by T-grafting followed by T-budding (22.58%). Early sprouting (7.90, days), maximum rooting rate (90.73%), maximum, number of secondary roots (30.82), more leaves, 45 days after transferring into bags of polyethylene, shoots of guava cv. respect to growth and production. can vary between 70 and 92%.” (Singh, 2007). Although guava is hard-to-root, investigations have indicated that it can be successfully propagated from cuttings under mist. It is now known that, treatment with etiolation increases the temporary, accumulation of endogenous growth substances, in the etiolate portion due to some anatomical, abnormalities, which promote better root rooting. mixture of 2,4-D and other auxin or cytokinins.
