Abstract
Promotion of development of cucumber fruit (Cucumis sativus L. cv. Chojitsuochiai No. 2) was achieved by the application of gibberellin A3 (GA3) and gibberellin A4+7 (GA4+7) to its flower. The promotive activity of GA4+7 was much greater than that of GA3. Their activities increased in parallel with higher concentrations. The promotive activities of gibberellin A4 (GA4) and gibberellin A7 (GA7) were also higher than GA3.The level of endogenous gibberellins in the placental tissue and the sarcocarp of parthenocarpic fruits was examined in relation to their development by using thin layer chromatography (TLC) followed by the rice seedling test. Three zones of gibberellin activity were found in the acidic and the nonacidic fraction from each of the fruit tissues. These zones were co-chromatographed on TLC with GA3, GA4/GA7 and gibberellin A9 (GA9). Total amounts of three gibberellins in both placental tissue and sarcocarp increased with development of the fruit which fitted with a role for gibberellins in promoting development of cucumber fruit. Existence of larger amounts of the gibberellins in the placental tissue suggests a potential for production of parthenocarpic fruit in this variety of cucumber.
