Abstract : Twelve nursery trials were conducted during 1995-96 in Egypt, where 1-year-old Hindi Bisinara mango seedlings were subjected to one or more of the following cultural practices: (a) control (sprayed with tap water); (b) root shortening to 20 cm below the crown; (c) stem pinching by removing 5 cm of stem tip; (d) root shortening + stem pinching; and/or (e) shoots and roots of the seedlings were treated either with paclobutrazol (PP333; 2000 ppm) or TIBA (100 ppm). Root shortening + stem pinching + spraying seedling shoots with paclobutrazol or TIBA were the most effective treatments in enhancing root and shoot branching and improving growth parameters as well as increasing leaf contents of N, Ca, Mg, Fe and Zn.
