Effects of Prohexadione Calcium Applications on Growth and Yield Characteristics of Cucumber (Cucumis sativus L.)

This study was conducted to determine the effects of growth regulator prohexadione calcium (Pro-Ca) and inhibitor gibberellic acid on some parameters (yield, pigment levels leaves, nutrient contents, proline, enzyme activities fruit quality) when applied at different doses (0, 15, 30, 45, 60 mg L-1). Chemicals were after transplanting seedlings. A total 12 plots including 3 plants for each dose used in randomised plot experimental design. Although it has a positive effect leaf proline content activities, L-1 Pro-Ca had negative morphological (excluding stem diameter), yield, chlorophyll a) contents compared control. High generally affected quality properties positively while 15 did not affect other parameters, except decreasing yield. 30 most effective examined parameters. The highest vegetative development, uptake obtained from subjected dose. Moreover, this increased firmness, TSS, EC values Being an important criterion cucumber storage harvest, weight loss rate 29.4% lower fruits plant having that control plants. Therefore, application, beside its growth, yield quality, can be suggested also increase shelf life cultivation greenhouse.
