Effect of IBA concentration and cultivars on number of leaves, leaf area and chlorophyll content of leaf in Pomegranate (Punica granatum L.) cuttings under temperate conditions of Kashmir

Abstract

Studies on the Influence of Indole Butyric Acid on total number of leaves, leaf area and total chlorophyll content per leaf of Pomegranate (Punica granatum L.) cuttings cvs. Chawla, Nabha and Kandhari Kabuli, Ichakdana, Bhagwa, Arakta, Muskat, Mridula, P- 23 and Jodhpur Red was conducted at the Division of Fruit Science, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Shalimar campus, J& K. The experiment was laid out in randomized complete block design (RCBD) comprising of hardwood cuttings and different IBA concentrations (1000, 2000, 3000, 4000 ppm IBA and control), replicated thrice. Among all the cultivars, maximum values in terms of leaves (30.30 and 26.47), leaf area (25.56 and 24.95 cm2) and chlorophyll per cutting (30.16 and 28.32) were recorded in the cvs. Kandhari Kabuli and Nabha, respectively as compared to control. The interaction of cultivar and growth regulator significantly affected the leaf number and leaf area per cutting. The interaction of cultivar and growth regulator significantly affected leaf number and leaf area per cutting. Number of leaves (36.57 and 31.31) and leaf area (34.05 and 29.24 cm2) were recorded significantly maximum values in the cvs. Kandhari Kabuli and Nabha, respectively with IBA @ 5000 ppm as compared to control. For all the parameters IBA@ 5000 ppm performed better followed by 4000 and 3000 ppm and least was reported in control.
