Effect of Ethephon, Gibberellic Acid, and Maleic Hydrazide on Vegetative Growth, Flowering, and Fruiting of Cucurbitaceous Crops

Year: 1985

Type: article

Abstract: A study on the effect of ethephon, GA 3 , MH, and NAA on vegetative growth, flowering, and yield of bottle gourd [ Lagenaria siceraria (Mol.) Standi.], round melon ( Citrullus vulgaris ‘Fistulosus’), sponge gourd ( Luffa cylindrica Roem.), summer squash ( Cucurbita pepo L.), and watermelon ( Citrullus lanatus Thunb. Matsum & Nakai) was conducted from 1979–1982. Maleic hydrazide applied at 150 mg/liter to bottle gourd and at 50 mg/liter to round melon, ethephon at 100 mg/liter to sponge gourd and at 250 mg/liter to summer squash, and GA 3 at 25 mg/liter to watermelon were most effective in stimulating the elongation of main stem (except in summer squash), increasing branches per plant, lowering the male : female flower ratio, setting additional fruit, and producing highest fruit yield as compared to the untreated control. Chemical names used. (2-chloroethyl)phosphonic acid (ethephon); gibberellic acid (GA 3 ); 1, 2-dihydro-3, 6-pyridazinedione (MH); 1-naphthaleneacetic acid (NAA).
