“…Maximum number of bulbs per plant was recorded with 400 ppm GA 3 (1.43) followed by 500 ppm CCC (1.41) over the control (1.07). Similar results were recorded by Kumar et al (2008) in gladiolus with GA 3 and CCC application and Hetman et al (1992) in tulip with CCC application. Bulbs weight per plant was recorded maximum with 400 ppm GA 3 (19.36 g) followed by 500 ppm CCC (17.66 g) in comparison with the control (12.76 g).…”

A study was carried out to evaluate the effect of plant growth regulators on growth, flowering and bulb production of tulip under Karewa conditions of Kashmir Himalaya during 2009 to 2011. The three different growth regulators; gibberellic acid (GA 3) at 100, 200, and 400 ppm, 2-chloroethyl trimethyl ammonium chloride (CCC) and maleic hydrazide (MH) each at 100, 200 and 500 ppm along with control were applied as dip treatment and foliar spray. Plant height was recorded maximum with 400 ppm GA 3 (37.32 cm) followed by 200 ppm GA 3 (34.13 cm). GA 3 at 400 ppm significantly caused earliest flowering (141.30 days) followed by 200 ppm GA 3 (142.43 days) as compared to the control (148.93 days), while delayed flowering were observed by 500 ppm MH (152.96 days) followed by 200 ppm MH (151.93 days). The longest blooming period was recorded in 200 ppm GA 3 (28.46 days) followed by 400 ppm GA 3 (27.76 days) in comparison to the control (21.59 days). The maximum vase life was obtained with 400 ppm GA 3 (11.26 days) followed by 200 ppm GA 3 (10.43 days) over the control (7.30 days). The maximum number of bulbs and daughter bulbs per plant were recorded with 400 ppm GA 3 (1.43 and 3.03) followed by 500 ppm CCC (1.41 and 2.65) over the control (1.07 and 1.72), respectively and thereby enhanced propagation coefficient was obtained in 400 ppm GA 3 (258.66%) followed by 500 ppm CCC (237.73%) as against the control (170.00%).
