Effect of IBA and PHB on roots and shoots of pomegranate (Punica granatum L.) cuttings cv. Ganesh

Abstract

In order to study the effect of IBA and PHB on rooting and shooting of pomegranate (Punica granatum L.) cuttings an investigation was conducted at the nursery of Department of Horticulture, Khalsa College, and Amritsar during 2015-2016. Seven treatments were used comprising of IBA (500ppm, 1000ppm) and PHB (500 ppm, 750 ppm), their combinations IBA 500 ppm + PHB 500 ppm and IBA 1000 ppm + PHB 750 ppm along with control. The results of the investigation indicated that IBA 1000 ppm + PHB 750 ppm proved to be the best in terms of maximum percentage of sprouted cuttings (86.40%), survival percentage (86.73%), number of shoots (7.71), average shoot diameter (1.29cm), number of leaves (126.00), total leaf area (259.48 cm²), maximum number of roots (24.65), maximum root length (15.40cm) and maximum root weight (2.4 g).
