7th ed. Cultivation of young guava, 1987). 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. In recent times, stooling has been found cheapest and easiest method of propagation. The roots are cut about 0.5-1, m from the trunk of a mature tree.” The shoots that, grow during root cutting are removed with their, method, however, it is possible to induce guava wilt, disease through the root wounds, which is why it, is not recommended. The rootstock stem is separated between 15 to. International Journal of Biological, of somatic embryogenesis regenerated guava, concentrations of IBA on rooting of Guava, Psidium guajava L. in low tunnel under shady. In case of seed germination, the highest germination percentage was recorded under GA3 (1000 and 500 ppm) concentration. The Introducción. In layering, the success is dependent on early root initiation and formation of sufficient fibrous roots. The selected shoots, must be 500 mm from the tip to the point where, to 40 mm wide, is peeled off around the chosen, branch. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. Planting seeds Guava seeds are usually started in nursery beds or pots before being transplanted in the field or garden. This technique can, produce up to 95% of success, but more laborious as, compare to cutting or layering. 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 old. Ascorbic acid and L-glutamine which are sources of. 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. plants with essential characteristics is required. Guava seeds for. Termos para indexação: Psidium guajava, semente, enxertia, estaquia, alporquia, cultura de tecidos. How to Propagate Guava Cuttings. By contrast, IBA was more effective only in soft wood cuttings. The various propagation techniques are available, but. IBA 5000 ppm and poultry manure combination was found to be second best for survival of air layering. 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. and pulmonary disease in Bolivia and Egypt (Batick, 1984). embryogenesis helps to study plant differentiation, totipotent cell expression level also and has been, Safeda and Banarasi cultivars, using the zygotic, embryos as explants. 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. Seedlings are ready for field transplanting or used as rootstocks when they are six months to one year old. Khan3 1Agricultural Research Institute, Tarnab, Peshawar 2,3Department of Horticulture, University of Agriculture, Faisalabad, Pakistan Abstract: Macropropagation of guava (Psidium guajava L.) cv. 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. (2007) [53, 68, 81, 82] observed that the combination of IBA with rooting media helped in producing maximum number of primary roots, secondary roots, leaves on 60 days and length of shoots on 60 days. Propagation and Rootstock of Guava. Since there is no root problem with, this method, the use of rooting hormones is not, essential. Environmental conditions can affect the, ability of cuttings to grow and induce root. On average, maximum of (2.5) roots were also recorded per explants in 42 days. 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. Genotypic variation of rootstocks for growth and production in cucumber; possibilities for improving... A review: Macro-propagation of guava (Psidium guajava). Propagation – guava is commonly multiplied by seeds. The predominant 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. species of trees and shrubs, many of which have edible fruits. A, different growth regulators and types of cuttings. cultivation in 3-Butyric acid, the cuttings had not induced root. Irrespective of cutting type, IAA and NAA seem to be the most efficient in promoting roots. 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 methods of vegetative propagation have been, studied for the purpose of the production chain. of Softwood Grafting in Guava (Psidium guajava. demonstrated by the maximum number of shoots, the number of leaves and the length of the shoots, to 90 days from the separation of the layers of, mother plants placed in the shade of the house for, ground during the dormant season and covered. However, guava hardwood cuttings were found hard to root (Luis et al., 1986) [33]. The guava plants can be propagated through seed, inarching, layering, cutting, budding and grafting. Red fleshed fruit contains 3 mg of carotene/100 g of fruit. However, when the concentration of glutamin alone was increased from 250 to 500 mgl-1 the shoot formation potential of explant decreased to 10%. 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). 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). There are many plants that Plant materials used in the grafting process, should be treated before use against diseases due to, fungus. Research Article : A Break Through in Guava (Psidium guajava L.) Propagation from Cutting. respect to growth and production. 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. Therefore, After leaving the time necessary to start the root, rooted shoots are separated and taken as individual, layers. increased the number of leaves (16) per cutting. were higher than the control with the highest, percentage of seed germination, the seed strength. Introduction Guava (Psidium guajava L.) belong to family Myrtaceae. Comparatively IAA was stronger than IBA in sprouting for both types of cuttings. Other aspects of guava cultivation. Diversas são as tecnologias de propagação disponíveis; entretanto, os níveis de adoção são bastante diferentes entre os países produtores. productivity is not recommended (Pereira, 1990). 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. UniversidadeFederaldePelotas,Pelotas;66. The maximum number of roots (27.6) per cutting was recorded in soft wood cuttings treated with IAA. and quality with special reference to São Paulo, growth regulators and types of cuttings on rooting, ABA and sucrose on germination of encapsulated, of method and time of propagation in guava, of IBA concentrations on guava stooling and, plantlets survival under open and polyhouse. fruit is an excellent source of vitamin-C (Rathore, 1976; Yadava, 1994), which is upto 2000 But how do you start growing a guava tree? In various transplantation methods, budding and, grafting have achieved the highest success rates in, the propagation of different guava varieties. 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. 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. In case of grafting, wedge grafting in the month of August gave better results in polyhouse (69.88 %) as well as in open field condition (67.12 %). During summer cultivation, rootstocks of cultivar ‘Glabrous’ promoted maximal vegetative growth of the scion, and rootstock Code D induced the highest fruit yield. using leaf disc as explant in guava cultivars. Care must be taken that the propagation, material comes from the best plant without disease, symptoms. air layering was used only by the highly trained plantsman. All shoots growing under the graft, should be removed regularly to avoid competition, developed root system of the rootstock. In vitro shoot proliferation and propagation of guava (Psidium guajava L.) from germinated seedlings Clonal propagation is a process of asexually reproducing plants by multiplication of one copy to produce several copies that are genetically identical. Roots of Peace VEGETATIVE PROPAGATION TECHNIQUES Page 2 This manual was produced by Roots of Peace under USAID subcontract No. In a first grafting experiment with five rootstocks and three scions different rootstocks led to differences in growth and production of the scion. on rooting of guava (Psidium guajava L.). safeda. 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). Content may be subject to copyright. oportoalegre:vecontinents.cap.;5:85-111. In this situation there is, a genetic variability in root systems, in particular, there is a variation in the strength. D.B. 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. Sin embargo, actualmente existe una serie de ofertas tecnológicas que pueden ser implementadas para abordar las principales limitantes del cultivo, logrando como resultado mejorar la producción de guayaba de manera rentable y ambientalmente sostenible. The seed propagation is now restricted to raising of rootstock materials. The number of leaves in soft wood cuttings treated with either IBA or IAA and NAA were greater than semi hard wood cuttings. Its use for propagation is limited to breeding plan. proliferation on nodal explants of mature trees. Plants can be vegetatively propagated using many different tissues, including the roots (breadfruit), stems (guava), apices (banana), and buds (citrus). were the second best for the survival of air layers. The disadvantage is. Guava plants grown directly from seed give poor fruit yield and quality, and come into bearing late. The purpose of this review is to discuss, the diverse methods of propagating guava which, are used commercially and the advancement made, raising the rootstock materials. The air layers guava. Then the, seeds are extracted, washed with running water, and dried in the shade for 10 days. Wedge grafting in the month of August gave better results in polyhouse (69.88 %) as well as in open field condition (67.12 %). in vitro can facilitate rapid clonal propagation. technology is not used, guava is still propagated, with seeds. it results in low productivity and low fruit quality, (Pereira, 1990). with different degrees of success (Jaffco,1970). 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. GS-10F-0359M, Task Order #306-M-00-05-00515-00, Afghanistan Alternative Livelihoods Program This, exercise helps the swollen buds that can sprout, once the transplant is complete. tropical fruit-6: guava. Maximum number of explants (76.6%) responded to rooting with 1.5 mgl-1 IAA in combination with 1.0 mgl-1 NAA. rootstock may be grafted and diameter of about 5, -7mm. 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. and quality (Dhua and Sen, 1984). Propagation by seed is used for rootstock production and for raising populations for screening at early phases in the breeding programs. 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. Necessidades para melhorias na formação de mudas de goiabeira são discutidas. 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. 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, 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. There is great of demand for true to type plants of guava. can vary between 70 and 92%.” (Singh, 2007). Apical stem branches is used, to perform the grafting, this should be 3 or 4 months. On the same media after 38-days of culturing, maximum number of 3.6 shoots per explant, 2.6 cm long was also recorded. 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.
