Effect of Indole-3-Butyric Acid on Growth of V-1 Mulberry Cuttings with Varying Number of Buds in Bangalore

Abstract

The present study was conducted in Bangalore. It aims at studying the effect of different concentrations of indole-3-butyric acid (IBA) (1000, 2000 and 3000 ppm) on V-1 mulberry cuttings with varying number of buds (one, two, three and four) consist of twelve treatments which were replicated thrice in Factorial CRD. The results on interaction effect of various concentration of IBA on mulberry cuttings with varying number of buds recorded best results in three budded cuttings treated with 3000 ppm of IBA regarding number of sprouted cuttings (14.67) and survival percentage (96.66%) of the saplings. Number of leaves (10.60) and length of shoot (26.63 cm) was maximum in two budded cuttings treated with 3000 ppm of IBA and the results of this interaction were on par with three budded cuttings treated with 3000 ppm of IBA. Whereas, one budded cutting without IBA treatment recorded minimum number of sprouted cuttings (9.67), survival percentage (43.33%), number of leaves (5.67) and length of shoot (21.43 cm). From the present experiment, we can recommend to use two budded cuttings treated with 3000 ppm of IBA instead of three budded cuttings treated with 3000 ppm of IBA.
