摘　　要：以蛭石、赤霉酸(GA3)和聚乙二醇(PEG)为引发方式,研究了不同蛭石含水量、溶液处理浓度和处理时间对葫芦种子萌发的影响。结果表明:与对照相比,在适宜的引发条件下3种引发方式均可提高葫芦种子的发芽率,以蛭石含水量50%处理72 h效果最佳,种子发芽势、发芽率分别比对照提高64.10%和24.76%,发芽时间明显缩短。The effects of vermiculite priming,gibberellic acid（GA3） priming and polyethylene glycol（PEG） priming on the seed germination of bottle gourd seeds（Lagenaria siceraria Standl.） were studied.The results showed that compared with control,the three priming methods could increase germination rate under optimal conditions.But 50% of water content in vermiculite primed 72 hours was the optimal method for the priming of bottle gourd seeds,the germination energy and germination rate were enhanced by 64.10% and 24.76% respectively,and the mean germination time was shortened obviously.
