The present investigation entitled “Effect of pinching and growth regulators on vegetative and physiological parameters of chrysanthemum (Dendranthema morifolium) cv. Pusa Kesari” was carried out at College of Horticulture, Venkataramannagudem, Dr. Horticultural University, during Kharif 2017. The experiment was conducted in Randomized Block Design with Fifteen treatment combinations comprising of 3 levels of pinching . No pinching, Single pinching and Double pinching and 5 levels of growth regulators ., GA3 @ 100 ppm, GA3 @ 200 ppm, Triacontanol @ 50 ppm, Triacontanol @ 100 ppm and Water spray) replicated thrice and the observations were recorded for vegetative and physiological parameters of chrysanthemum among all treatment combinations the maximum plant spread, number of leaves plant-1 , leaf area plant-1 , leaf area index, leaf area duration,, number of suckers plant-1 , crop growth rate, relative growth rate, net assimilation rate, total chlorophyll content, fresh weight plant-1 and dry weight plant-1 were recorded in double pinched plants sprayed with triacontanol @ 50 ppm. The maximum plant height and absolute growth rate was recorded in plants without pinching and sprayed with GA3 @ 200 ppm. Hence on the basis of results obtained from the present investigation it can be concluded that the double pinched plants sprayed with triacontanol @ 50 ppm was found effective with respect to vegetative and physiological parameters. | Effect of pinching and growth regulators on vegetative and physiological parameters
