Abstract

The experiment entitled, “Effect of bulb size and growth regulators on flowering and flower yield of tuberose (Polyanthes tuberosa L.) cv. Double” was carried out at Horticulture Instructional Farm, College of Agriculture, Junagadh Agriculture University, Junagadh during 2006-07. Treatment of small daughter bulbs S4 found superior and in case of number of leaves per plant at 100 DAP (69.38) mother bulbs (S1) was found better. Maximum plant height (46.78 cm) was recorded in large daughter bulbs (S2). With respect to flower characters, earlier spike emergence (111.7 days), maximum number of spikes per plant (2.5), per net plot (87.5), per hector (276666), highest number of florets per spike (30.52), maximum floret diameter (31.7mm), longest spike (66.77cm), as well as with vase life (10.63 days) was recorded in large daughter bulbs (S2). Thiourea at 1000 ppm (G1) resulted in outstanding superiority for most of the vegetative and flowering parameters under trial. Maximum plant height (46.28 cm) and number of leaves (65.63) at 100 DAP was resulted in thiourea 1000 ppm. The flowering parameters like number of spikes per plant (2.1), per net plot (73.5), and per hector (229630), number of florets per spike (29.89), diameter of floret (31.4 mm), length of spike (64.30 cm) and vase life (10.55 days) were found to be significantly best with same treatment.
