Effect of Different Growth Regulators on Root Induction of Light Weight Date Palm Suckers

Abstract

The present investigation was carried out at Horticultural Research Institute, Ayub Agricultural Research Institute, Faisalabad during 2017-2019 to evaluate the effect of different growth regulators on root induction of Date palm suckers. There were six treatments i.e., T0 (Control), T1 (Indol butyric Acid (IBA) @2000 ppm), T2 (IBA@4000 ppm), T3 (Naphthalene Acetic Acid (NAA) @2000 ppm), T4 (NAA@3000), T5 (IBA@2000 ppm + NAA@2000 ppm). Growth regulators significantly affected the survival percentage, number of leaves, leaf length and number of roots plant-1. Results showed that IBA@4000 ppm gave maximum success percentage (76.3%), highest survival percentage after 90 days (43.8%), maximum number of leaves (4.5), highest leaf length (20.6cm) and highest number of roots plant-1 (24.8). In view of these results, it is concluded that IBA can be used @ 4000 ppm for better root induction of Date palm suckers.
