Cucumber fruit size and seed yield affected by growth regulators

摘要

Gibherellic acid (GA3) was used to induce male flowers on a parthenocarpic, gynoecious hybrid cucumber (Cucumis sativus) 'Polonez F,'. GA3 treatment resulted in increased fruit volume and weight. This was accompanied by a considerable increase in fruit seed yield which was attributable to a statistically non-significant increase in the number of seeds per fruit combined with a similar increase in seed size. During blooming and pollination, plants were treated with 2,4-dichlorophenoxyacetic acid (2,4D) in concentrations of 0.005% and 0.01%. This treatment did not reduce fertility. No bi-embryonic seeds were found.
