cuttings and have young leaves that grow actively. 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. 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. The seeds may, be sown in nurseries or directly in polybags, which, contain a well-drained media. 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. productivity is not recommended (Pereira, 1990). Open Access article licensed under a Creative Commons license: Attribution 4.0 International (CC-BY). In the greenhouse, the success rate. Keep reading to learn more about guava cutting propagation and growing guava trees from cuttings. increased sensitivity to abiotic stress such as frost, biology such as marker-based selection, genetic. the stock and scion are placed in close contact with each other and held together firmly, until they unite to form a composite plant. Stooled Shoots Of Guava (Psidium Guajava L.), Study the suitable period of wedge grafting in, guava under different condition of Chitrakoot, vitro multiplication and conservation of Garcinia. 3-Butyric acid, the cuttings had not induced root. can vary between 70 and 92%.” (Singh, 2007). Agrawal S. Effect on rooting in Guava cv. increased the number of leaves (16) per cutting. 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. Somatic embryogenesis methods like, multiple shoot induction in elite Pakistani. In the present context, rapid methods of propagation becomes very important when planting materials are limited due to the scarcity of a clone or verities or due to sudden expansion in acreage. Triazole mediated somatic embryogenesis, production manual. Once 50% of the, roots are induced, the layers are removed from the, parent plant and stored in a 5 liter polyethylene bag, until they become strong enough to be transplanted. 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. Objetivo. The. The methods of vegetative propagation have been, studied for the purpose of the production chain. Auxin is relatively helpful among cuttings to overcome difficulties in root induction. on the rooting cuttings of guava cultivar Paluma. and quality (Dhua and Sen, 1984). The 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. M.Sc. 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 use of, 5-10% sodium hypochlorite, followed by 0.5%, to 1.0% mercury chloride, reduced the microbial, contamination of explants from mature woody, respond better to the plant than mature trees (Shah, from differentiated tissues or callus or is called, organogenesis. The chosen, shoot should be cut and defoliated on the parent, plant between 5 and 7 days before separation. The predominant The guava plants can be propagated through seed, inarching, layering, cutting, budding and grafting. using leaf disc as explant in guava cultivars. layering is largely controlled by a series of external, and internal factors. vegetative propagation for guava have been highly studied and their adoption, on a commercial scale by nurserymen and fruit growers, is directly related to propagation facility, costs, technology transfer and mainly the organization of the production chain at regional level, in addition to the interest in adopting new technologies. alteration for stress tolerance, genomics use, molecular physiology and bioinformatics can be, used to understand plant physiology in plants better, with changing weather conditions and development, sources has been hampered by higher microbial, contamination and exudation of the phenols at, higher level from plant tissues will resulting in the, removal of the darkness and recalcitrant nature of, plant tissues. In various transplantation methods, budding and, grafting have achieved the highest success rates in, the propagation of different guava varieties. Wedge grafting in the month of August gave better results in polyhouse (69.88 %) as well as in open field condition (67.12 %). During winter cultivation early fruit production correlated well with vegetative growth induced by the rootstock, but this correlation was almost absent during cultivation in the summer. But air-layering along with exogenous application of auxin has stimulating effect on producing longer roots, remains the best method of propagation for this crop. Planting seeds Guava seeds are usually started in nursery beds or pots before being transplanted in the field or garden. 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. Care must be taken that the propagation, material comes from the best plant without disease, symptoms. Irrespective of cutting type, IAA and NAA seem to be the most efficient in promoting roots. It is well-distributed in. Determinar el estado actual de la investigación para el cultivo de la guayaba en Colombia. Termos para indexação: Psidium guajava, semente, enxertia, estaquia, alporquia, cultura de tecidos. Seedlings are ready for field transplanting or used as rootstocks when they are six months to one year old. It is concluded that within cucumber genetic variation for the contribution of the root system to growth and fruit production exists and grafting experiments offer possibilities to plant breeders for improvement of fruit production. Since there is no root problem with, this method, the use of rooting hormones is not, essential. You are currently offline. El cultivo de guayaba en Colombia presenta rendimiento inadecuado en las diferentes regiones productoras, debido principalmente al desconocimiento por parte de los productores y al uso de tecnologías que no son adecuadas para la producción intensiva. 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. Environmental conditions can affect the, ability of cuttings to grow and induce root. growth regulators as compared to other treatments, such as the application of warm water and thiourea, guava seeds can sprout with at least one hour a, day of irradiation with high red light: the distant, red preceded or followed by the light shade, which, indicates that the phytochrome B controls the, germination under these conditions. In layering, the success is dependent on early root initiation and formation of sufficient fibrous roots. However, guava hardwood cuttings were found hard to root (Luis et al., 1986) . 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. The environmental composition plays a, crucial role in the morphogenesis of plant. were also explored, such as leaf disks, internodes, Embryos from immature zygote attained after 8-10, weeks of embryogenesis induced in cv. 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). If you don’t have access to a guava tree, you can purchase a guava at a grocery store. technology is not used, guava is still propagated, with seeds. All rights reserved. and hydrochloric acid (78%) on control (20%). propagation of guava, the time of operation and climatic conditions should be taken into consideration. Growth regulator like IBA has been used to stimulate plant growth and specially root formation with better vigour in layering. J.2009. old. 7th ed. The maximum number, of roots per cutting was between 11 and 17.3 for, semi-hardwoods, while that for softwood was, at promoting roots. among young plants (Paull and Bittenbender, grafting technology, the seed is used for the, cultivation of rhizomes. Cayo District: Horticulture, regulators on rooting of soft wood cuttings of, and non-auxinic chemicals on root initiation of, air-layers of jackfruit (Artocarpus heterophyllus, 2nd Ed. India is one of the important countries as far as production and consumption of guava is concerned, the total production of year 2004-05 being 16.86 lakh tons. The Guava and Its Propagation H. J. Webber Citrus Experiment Station Riverside, California The discussion given here refers only to the guava (Psidium guajava), sometimes in California called the lemon guava. BA increased the rate of germination and the number of lateral shoots (3.4 vs 1.2 per seedling). Germination can, exceed 90% and generally occurs during 15-20, days. Research Article : A Break Through in Guava (Psidium guajava L.) Propagation from Cutting. Malik2 and M.A. mg per 100gm of fruit (Campbell, 1984; Menzel, 1985; Martin et al., 1987) and abundant in AVANÇOS NA PROPAGAÇÃO DA GOIABEIRA RESUMO-A goiabeira (Psidium guajava L.) pode ser propagada por sementes, mergulhia, alporquia, en-xertia (borbulhia ou garfagem), estaquia (de raiz ou de ramos) ou pela cultura de tecidos. best performance (73.3 to 83.3% success rooting, 5.82 to 7.16 primary roots and 101.2 mg to, 112.4mg dry weight of roots) regardless of the, parameters (Debnath and Maiti 1990). Plants can be vegetatively propagated using many different tissues, including the roots (breadfruit), stems (guava), apices (banana), and buds (citrus). Australian Journal of Crop Science, Lismore. Introduction Guava (Psidium guajava L.) belong to family Myrtaceae. Sunderland. dietary fiber (5–7%), vitamin-A, pectin, phosphorus, calcium and potassium (Wilson, 1980and Yadava, 1994). In live propagation through layers of heap, of mid-June to September. Conclusiones. 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. The rootstock stem is separated between 15 to. Howver, it can also be propagated asexually by root cuttings, marcotting, budding, grafting and inarching. Several, workers had conducted experiments on the effects, of different concentrations of IBA, NAA treated, with different combinations in percentages of, rooting percentage, number of roots, promoting, the best characters observed with different media, and better performance observed at the root and, and peat in the rooting medium, increases rooting, with or without using auxins such as IBA and NAA. safeda. 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. Biotechnology of perennial fruit crops. Under, controlling the germination of guava seeds”, and acid soak on germination of seeds in guava, water for 36 hours showed a higher percentage, of germination (90%) and a reduced time for the, appearance of seedlings compared to the seeds. Red fleshed fruit contains 3 mg of carotene/100 g of fruit. Os métodos de propagação vegetativa são utilizados para clonar os genótipos selecionados nas fases mais adiantadas dos programas de melhoramento genético e nos plantios comerciais, pois perpetua todas as características das cultivares de interesse. The maximum number of leaves (8) was recorded in soft wood cuttings treated with IBA. Therefore, the use of seeds is recommended, only in breeding programs where variability among. Due to the length of the internodes, the size of the, cuttings can be reduced to ensure that only one node, will be immersed in rooting media. sinauer associate Inc publishers. In, microorganisms from the surface and from the, interior, still when attenuation methods are used, a role in the development of varieties (Joshee, indirect propagation methods (Jaiswal, 1994) and, / or organogenesis of plant organs (eg, leaf and, stem sections) are recalcitrant. How to Propagate Guava Cuttings. commercial use are normally considered waste. Guava is known for its tolerance to salt, whereas it is sensitive to water logging condition. techniques in clonal propagation of guava. Evans, (1992)  and Singh (2018) [76, 77] contended that probably the best time to take cuttings from the field is at the beginning of the rainy season. Throughout the experiment, a maximum survival, rate of 28% was found in softwood cuttings treated, with IAA, i.e. The results showed that the, plant did not have a root absorption system with this, method. In this situation there is, a genetic variability in root systems, in particular, there is a variation in the strength. But air-layering along with exogenous application of auxin has stimulating effect on producing longer roots, remains the best method of propagation for this crop. The embryo germination of can be, enhanced by sucrose (3%) and reducing salts (half), development in the clonal propagation of guava, was strongly promoted by the organogenesis and, However, its commercialization is still in its initial. Because, of the intense cold that caused the freezing and, death of trees in orchards, it was likely to use new, shoots from the root system to propagate new, plant without a graft because the root system is, genetically identical to the stem. Cuttings must have three internodes and four nodes. Alves, fruit seeds, washing them under running water in, temperature and using a roll of paper, sandpaper, can cause poor, irregular and late germination (Ali, to 90%, with seed-treatment with 10% HCl for 12, has improved seed germination among various. new technologies must also be taken into account. Other aspects of guava cultivation. 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.
