An experiment was conducted at the nursery of Department of Horticulture, Khalsa College, Amritsar during 2019-2020 to study the role of growth regulators and sucrose in sprouting and establishment of pomegranate cuttings. A trial was undertaken comprised of thirteen treatments of semihard wood cuttings of pomegranate cv. Kandhari viz. IBA (1000, 2000 and 3000 ppm), Sucrose (10, 20 and 30g/l), PHB (500, 750 and 1000 ppm) and NAA (1000, 2000 and 3000 ppm) by quick dip method along with control and the experiment was replicated thrice. The experimental results indicated that Sucrose 20g/l proved to be the best in terms of minimum days to first sprouting (9.00), maximum sprouting percentage (85.72%), maximum shoot length ( 18.50 cm), maximum shoot formation ( 9.00), maximum shoot diameter ( 2.61 mm), maximum fresh weight of shoot (1.38 g), maximum dry weight of shoot (0.92g), maximum number of leaves ( 65.00) and maximum total leaf area (357.42 cm2).
