Abstract

The present work was studied to modify the floral and yield contributing characters of tuberose by the influence of gibberellic acid. During the experiment four treatments were tested: control, 100 ppm, 200 ppm and 300 ppm with three replications. The experiment was conducted over two growing periods during April 2013 to March 2015 at Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh. Gibberellic acid regulated the development of spike, bulb and bulblet. GA3 @ 200 ppm was more effectiveon floral initiation, floret iflorescence-1, bulb and bulblet production compared to control. Maximum flowering plants about 92.56%, bulb yield about 15.86 t ha-1 and bulblet yield about 13.60 t ha-1 were found from the plants treated with GA3 @ 200 ppm. Therefore, GA3 @ 200 ppm were found to be effective for the tuberose production rather than other treatments.
