摘　　要： 苗期、花期外源激素处理对西葫芦化瓜影响的研究表明,苗期乙烯利处理有利于雌花形成,但不利于座瓜,品种间化瓜率的高低依次是:早青一代> 南韩极早> 黑美丽,幼瓜的发育更容易受到花期外源激素的影响。在开花期用激素喷施柱头,均能够提高座瓜率,但提高的程度不同,其中40 mg/L2 ,4D+ 100 mg/LGA3 与100 mg/LNAA 是两种最有效的处理。从每一种激素处理的结果看,若发生化瓜,必将在花后4 ～6 天,6 天后开始从外形上可见,而正常生长的幼瓜从花后6 天开始进入迅速生长期。 The effect of exotic hormone treatments during seedling stage and flowering stage on abortive fruit of pumpkin.It is proved that 2 chloroethyl phosphonic treatments are more effective to female flowers' formation but not useful to set of fruits.Among the varieties the rate of abortive fruit from high to low is Zaoqing No.1>Koreajizao>Blackbeauty.Development of young fruits has more sensitive reaction to exotic hormone treatments during flowering than during seedling stage.The rate of set increases when spraying hormone on stigma during flowering,however each kind of hormone acts in different level.The most two efefctive treatments are 40 mg/L 2,4 d+100 mg/L GA\-3 and 100 mg/L NAA.If furit aborts finally it must happen in 4～6 days after flowering and showed in appearance.The normal fruit will grow quicker 6 days flowering.\;
