Effect of Benzyladenine Plus Gibberellins and Gibberellic Acid on Yield and Yield Components of Cucumber (Cucumis sativus L. cv. ‘tempo’)

Abstract

Two greenhouse trials were carried out to evaluate the effect of benzyladenine plus gibberellins (GA4+7) and gibberellic acid (GA3) on yield and yield components of cucumber. Gibberellic acid significantly increased leaf number per plant compared to control plants. Benzyladenine plus GA4+7 at 25, 50, or 75 mg L-1 significantly increased cucumber leaf size, flower number, fruit number, fruit yield and mean fruit weight compared to fruit from control cucumber plants. Gibberellic acid and benzyladenine (BA) plus GA4+7 at 25, 50, or 75 mg L-1 significantly increased fresh fruit yield of cucumber plants. The increase in yield was linear with increasing GA3 concentration and quadratic with increasing BA plus GA4+7 concentration. The results of this study suggest that GA3 and BA plus GA4+7 have the potential to be used to in the culture of cucumber under greenhouse conditions.
