Influence of benzyl adenine and gibberellic acid on morphological behaviour of Asiatic lily

Abstract

An experiment on “Influence of benzyl adenine and gibberellic acid on morphological behaviour of Asiatic lily” was conducted at experimental block (protected condition) in the Department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere (under University of Agricultural and Horticultural Sciences, Shivamogga), during 2019-2020. The experiment comprises of 16 treatments alone and in combinations of benzyl adenine (50, 100 and 150 ppm), gibberellic acid (100,150 and 200 ppm) and control (water soaking) replicated thrice in Randomized Complete Block Design (RCBD). The GA3 @ 200 ppm exhibited earlier sprouting (6.00 days), maximum sprouting per cent (99.03), plant height (83.13 cm), number of leaves (67.25), leaf length (10.27 cm), leaf breadth (2.51 cm), leaf area (1139.00 cm2) and leaf area index (3.80). The Basal stem diameter (18.06 mm), chlorophyll-a (1.31 mg/g), chlorophyll-b (0.36 mg/g) and total chlorophyll (1.94 mg/g) recorded maximum in BA @ 150 ppm. While maximum days taken for bulb sprouting (12.12), minimum plant height (36.72 cm), number of leaves (29.33), leaf length (7.11 cm), leaf area (518.33 cm2) and leaf area index (1.71) recorded in the BA @ 150 ppm.
