METHODS OF PROPAGATION OF GUAVA (Psidium guajava): A REVIEW

Guava belongs to family Myrtaceae. The major components of guava fruits are vitamin ‘C’, carbohydrates and minerals. There are different methods of propagation used in Guava such as inarching, layering, cutting and budding. Layering specially air layering is a popular and commercially used for propagation of guava in India. The investigation on effect of plant growth regulators at different concentrations, minimum days for number of roots, root initiation, rooting media, root length, survival percentage of layers prepared in the months of February-March, July- August and December has been carried out. Regarding the time of layering, June is considered as the best month for air layering when indole-3-butyric acid (IBA) and Naphthalene acetic acid (NAA) are used as a combination. In the case of grafting, this was performed during second fortnight of February with grafts polycapped under open field condition gave highest graft success. In relation to budding, August month budding showed highest per cent of success.
