Abstract : Results of studies on air layering of 8 mango rootstocks (Neeleshwari, Neelum, Kesar, Velio, Alphonso, Vanraj, Rajapuri and Kalapad) carried out during the rainy season in 1993, 1994 and 1995 at the Agricultural Experimental Station, Paria, Gujarat, India are presented. Shoots (1.5- to- 2.0-year-old) were taken from 25-year-old trees and treated in July with IBA or NAA (each at 2500, 5000 or 10?000 ppm). The percentage of rooted layers was highest in Neeleshwari, Neelum and Kalapad rootstocks (71, 63 and 58%, respectively). The percentage of rooted layers was 36% in all other rootstocks. Percentage survival was low (30, 34 and 16% in Neeleshwari, Neelum and Kalapad, respectively, and 10% in all other rootstocks). Growth regulator application had no effect on rooting or survival and interactions between growth regulators and rootstocks were non-significant.
