Keyword:  乙烯利 黄瓜 种子期 雌性化效应;
Abstract: 用不同浓度的乙烯利,在黄瓜种子期进行不同时间的浸种处理,结果表明:在黄瓜的种子期用4000 ̄9000mg/L的乙烯利处理能降低黄瓜第一雌花节位、增加雌花数、减少雄花数、增加雌雄花比值,提高早期产量。浸种处理12h者,浓度以8000mg/L促雌效果最佳,其第一雌花节位比ck降低了1.45个节位,1 ̄30节内对1 ̄15节位雌性化作用效果明显,此节位段雌花数分别比ck增加了47.02%,48.13%,59.48%,且1 ̄30节单株总雌花数比ck增加了48.32%。浸种处理16h者,浓度以7000mg/L促雌效果为佳,其第一雌花节位比ck降低了1.38个节位,1 ̄30节内对1 ̄20节位雌性化作用效果最明显,此节位段雌花数分别比ck增加了41.24%,32.16%,40.26%,26.07%,且1 ̄30节单株总雌花数比ck增加32.83%。1 ̄30节单株总雄花数呈现递减趋势,7000mg/L处理12h的、8000mg/L处理16h的雄花数减少最少,分别比ck降低了29.77%,24.82%。两个处理时间以12h作用效果较为明显。
