Abstract

The experiment was conducted to study the effect of auxin and cytokinin on grafting and growth of sapling of guava (Psidium guajava L.) at department of Horticulture, College of Agriculture, ummedganj, KOTA, KVK Modal nursery Agriculture university Kota during the year of 2020-21.In the investigation, L-49 cultivar of guava (Psidium guajava L.) was selected as mother plant for obtaining scion bud. The foliar spray of NAA and BA (50 and 25 ppm each) either on rootstock or/and scion branch was applied 10 days prior to grafting. The most responsive treatments was foliar spray on rootstocks with BA at 25 ppm concentration. Rootstocks treated with BA (25 ppm) resulted in length of scion shoot after grafting (16.63 cm), diameter of sprouted scion (2.80 cm), diameter of rootstocks (3.41 cm), number of leaves (20.83), leaf area (24.76 cm2), number of lateral shoot (7.89) as compared to others treatments.

Keywords: Guava (Pidium guajava), grafting, plant growth regulators (NAA, BA)
