ABSTRACT
The present study on the effect of plant growth regulators on growth and flowering of chrysanthemum was carried out during 2014-15 at K.N.K. College of Horticulture, Mandsaur, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M.P.). The experiment was laid out in CRD with three replications. Chrysanthemum cultivar Hybrid- 2 was used for the experiment. Six PGR treatments consisting of three concentrations each of GA3 and NAA i.e., GA3 (100 ppm, 150 ppm and 200 ppm) and NAA (75 ppm, 125 ppm and 200 ppm) were applied. GA3 (200 ppm) recorded the maximum values for plant height, plant spread, number of leaves per plant, number of suckers per plant, number of flowers per plant, flower diameter and flowering duration as well as the earliest first flower bud appearance and first flower opening. This treatment also recorded the longest vase life of cut flowers (days), the maximum total water uptake in vase and the maximum diameter of fully opened flower in vase.
Key words :
Chrysanthemum, GA3, Growth attributes, Flower quality, NAA, PGR, Vase life.
