Abstract:

The effect of different levels of GA3 (40, 80, 120 and 160 ppm) and IBA (20, 40, 60 and 80 ppm) on the regulation of growth and flowering in Tuberose cv. Phule Rajani was studied. The bioregulators were applied as dip treatment of tuberose bulbs for 24 hrs before planting and as a spray 30 day after planting. The application of bioregulators; soaking as well as spraying, was found to be effective in manipulating the growth and flowering traits as compared to control. Soaking of the tuberose bulbs in 160ppm GA3 solution for 24 hours before planting significantly increased plant height (53.73cm) with highest number of leaves per plant (33.17) and width of leaf (23.97mm). It also registered minimum number of days for spike emergence (59.67). Significant increase in length of spike (63.77cm) and rachis (28.19cm), maximum number of spikes per plant (3.57), florets per spike (24.54), number of bulbs per plant (10.07), bulblets per plant (19.32), weight of bulbs per plant (194.62 gm) and highest vase life (9.87 days) was recorded in dipping treatment of tuberose bulbs in 160ppm GA3 for 24 hours before planting which was followed by the treatments; spraying with 160 ppm GA3, soaking in 80 ppm IBA and spraying of 80ppm IBA 30 days after planting.
