A field experiment entitled “Effect of GA3, alar and BA on flowering and vase life of China aster (Callistephus chinensis) was conducted at Horticulture Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during the year 2016-2017. China aster is a very popular winter annual flower crop and is mainly cultivated for production of cut flowers, loose flowers, as pot plant and for bedding plant purposes in landscape. Growth regulators play an important role in morphology and physiology of the plants and their effect varies with plant, species, variety, concentration used, method of application, frequency of applications etc. Treatment consisted of GA3 75 ppm and 150 ppm, alar 300 ppm and 600 ppm, BA (6-Benzyl Adenine) 20 ppm and 40 ppm along with control in a Randomized Block Design. The treatments were imposed as foliar sprays at 30 days after transplanting. Spraying of GA3 150 ppm resulted in early flowering and increased number of flowers per plant, fresh weight and dry weight of flowers. Among growth regulators foliar application of Alar also recorded for better flower quality parameters. Foliar spray of BA at 40 ppm enhanced vase life of China aster flower.
