Generally, cucumber plants have more male flowers than female flowers. The fewer
number of female flowers is one of the problems of cucumber production. Flowering
regulation can be performed by applying growth regulators and water management.
The study aims to determine the effects of paclobutrazol concentrations and watering
frequencies on the flowering ratio of cucumber plants. The experiment was arranged
in a factorial Randomized Completely Block Design at the Agricultural, Food, and
Fishery Extension Center, Seyegan, Yogyakarta. The first factor was the paclobutrazol
concentrations consisting of four levels (a control, 0.187 mL.L 1 , 0.375 mL.L 1 , and
0.562 mL.L 1). Meanwhile, the second factor was the watering frequency consisting
of three levels (once a day, once every two days, and once every three days). The ob
served data were performed using the analysis of variance (ANOVA) and followed
with Duncan’s Multiple Range Test at α= 5 %. The paclobutrazol concentrations
resulted in a significant effect on all of the observed variables. Meanwhile, watering
frequencies showed no significant effect on the male flowers, female flowers and
ratio of male to female flowers in cucumber. There was an interaction effect of
paclobutrazol concentration and watering frequency on the plant height and
flowering age of cucumber plants. The treatment of paclobutrazol at a concentration
of 0.375 mL.L 1, decreased of male flowers and increased of female flowers, reducing
the ratio of male and female flowers of cucumber plants at various watering
frequencies. |
