Effect of dikegulac on flowering, fruit setting and development of Cucumis sativus l.
Abstract
Foliar application of dikegulac sodium (2,3:4-6-di-O-isopropylidene-α-L-xylo-2-hexalofuranosate) had promotive effect on flowering, fruit setting and fruit development of Cucumis sativus. It suppressed male flowering and promoted female flowers. Dikegulac at 50mgl−1 increased the length and girth of the fruits by 46.3% and 81.5% respectively. With the same concentration, the weight of the fruits was increased by 38.8%. Dikegulac (50mg l−1) also improved the quality of the developing fruits by increasing the contents of insoluble carbohydrate and ascorbic acid in the fruits at 15 days of age.
