Abstract :

An investigation was carried out during 2014–15 to study the beneficial effects of plant growth regulators on induction of flowering in pomegranate cv. Bhagwa. Nine treatments with three growth regulators, viz., Ethrel at 150, 200 and 250 ppm, GA3 at 30, 40 and 50 ppm, NAA at 50,100 ppm and control (water spray) were sprayed at the time of initiation of new sprouts. Results revealed that application of ethrel at 250 ppm gave significantly maximum number of hermaphrodite flowers (25.22), minimum days taken for 50 (12.67) and 100 per cent (30.44) flowering and NAA at 100 ppm resulted in maximum length and diameter of the flowers as against control.
