Effect of Gibberellic acid on vegetative growth and mineral content(N,P,K) of mango seedling Mangifera indica L.

Abstract

This study was conducted in orchard in Abul-khassib province during the growing season 2006 in order to study the effect of Gibberellic acid (GA3) with (0,150,300 ml/L)concentration on some vegetative characters (plant height, stem diameter and the fresh &dry weight of the shoot & root system) and leaf mineral content (N,P,K) of mango (Mangifera indica L.) The seedlings were sprayed at two weeks interval from (6 of September) to(24 of December). Results showed that the spraying with (GA3) caused a significant increase in all vegetative characteristics. The mineral content of leaves increased with (GA3) treatments.
