VEGETATIVE PROPAGATION OF GUAVA (PSIDIUM GUAJAVA L.) THROUGH AIR LAYERING: A REVIEW.

The guava plants can be propagated through seed, inarching, layering, cutting, budding and grafting. 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. Growth regulator like IBA has been used to stimulate plant growth and specially root formation with better vigour in layering. The effects of auxins however are significantly influenced by environmental conditions, time and rooting media used. Therefore, this research was mainly conducted to find out the effects of various IBA concentration, time and rooting media on response and performance of rooting in air layering of Guava. In general, growth regulators viz., IBA alone and in combination with rooting media viz., Moss grass, Coco peat, and Moss grass + Coco peat is used in different time of layering viz., June, July favoured rooting in air-layers. It is being revealed that High percentage of rooting and root characters of air layers of guava can be successfully achieved by exogenous application of IBA in June and July. [ABSTRACT FROM AUTHOR]
