用乙烯利、赤霉素和吲哚丁酸浸种研究了外源激素对老化西葫芦种子活力及幼苗生长的影响。试验表明,不同浓度的乙烯利、赤霉素和吲哚丁酸,在不同的浸种时间下,对老化西葫芦种子活力的影响有明显差异。其中乙烯利200ppm,浸种24hr、赤霉素50ppm,浸种12hr和吲哚丁酸100ppm,浸种6hr,在提高老化西葫芦种子活力上效果更为明显。供试的三种外源激素对西葫芦幼苗生长的影响也有一定差异。 The effects of exogenous hormones on seed vigor and seedling growth of aged zucchini were studied by soaking the ethephon, gibberellin and indole butyric acid. The results showed that the effects of different concentrations of ethephon, gibberellin and indole butyric acid on seed vigor of aged zucchini under different soaking time were significantly different. The content of ethephon was 200ppm, soaking for 24hr, gibberellin 50ppm, soaking for 12hr and indole butyric acid 100ppm, soaking for 6hr, the effect was more obvious in improving the seed vigor of aged zucchini. The effects of the three exogenous hormones tested on the growth of zucchini seedlings were also different.
