Impact of plant growth regulators and pruning on flowering in Jasmine (Jasminum sambac L.)
Abstract
An investigation was carried out at Department of Floriculture and Landscape An investigation was carried out at Department of Floriculture and Landscape Architecture, College of Agriculture Vellanikkara to evaluate the effects of growth regulators and pruning on induction of off-season flowering in jasmine (Jasminum sambac L.). The experiment was laid out in randomized block design (with two factors) viz. time of pruning (factor 1) - last week of September, last week of October and last week of November, and application of growth regulators (factor 2) such as cycocel (1000 ppm, 1500 ppm), paclobutrazol (200 ppm, 300 ppm), mepiquat chloride (150 ppm, 300 ppm) GA3 (100 ppm, 150 ppm), with two replications. In the present study, P x G interaction had a significant effect on the days to bud initiation, number of cymes per plant and number of buds per plant. The treatment combination P1 x G1 (pruning during last week of September along with application of cycocel 1000 ppm) was found to give better flower yield during offseason.Downloads
