- Abstract
The results of the experiment revealed that the application of ethrel 200 ppm resulted in earliness to first pistillate flower appearance (34.30), delayed male flower appearance (32.78), highest female flowers per vine (41.40), minimum number of male flowers (253.46). Narrow sex ratio and female flower at lower node (6.12 and 11.99, respectively) were recorded with ethrel 200 ppm (8.75 and 15.30 respectively). Application of growth regulators at 2-4 leaf stage (S1) resulted in earliest first pistillate flower appearance with least number of days (35.42) followed by the application of growth regulators at four-leaf and flower initiation stage (S2). Lowest number of male flowers per vine (268.98) and lowest sex ratio (7.05) was recorded with two to fourleaf stage (S1) application. Highest number of female flowers per vine (38.23) was recorded with sprays at two to four-leaf stage (S1). Spraying of growth regulator at 2-4 leaf stage might have suppressed the male bud initiation and enhanced female flower bud initiation.
