摘要：

为优化解除菜豆种子硬实的条件,本试验以盛冠硬实种子为材料,通过比较不同温度的温水浸种、热水浸种和低温贮藏处理不同时间对解除种子硬实的影响,筛选出最佳的硬实破除条件。结果表明,盛冠菜豆种子含水量为14.28%时,种子硬实率为38%;未处理的硬实种子发芽率、发芽势和活力指数分别为26.5%,17%和23.17;经温水浸种、热水浸种和低温贮藏处理后的硬实种子均能一定程度解除种子硬实进而促进种子萌发,其中,各自处理的最佳条件分别是：60℃恒温浸种30 min,80℃恒温浸种 2 min以及-20℃贮藏7天。最后,比较3个处理间最佳的硬实破除条件,同时,考虑到菜豆种植的实际情况和硬实破除的最佳效果,对硬实率较高的盛冠菜豆种子用60℃恒温浸种30 min较适宜。

Abstract:

To optimize the conditions for removing hard seeds from snap bean seeds, the study screens out the best condition by comparing the effects of different temperatures of warm water immersion, hot water immersion and low temperature storage on the removal of hard seeds. The results showed that when the seed water content was 14.28%, the seed hard rate was 38%. The germination rate, germination potential and vigor index of untreated hard seeds were 26.5%, 17% and 23.17, respectively. The hard seeds soaked in warm water, hot water and stored at low temperature could relieve the hard seeds to a certain extent and promote the germination of seeds. The optimal conditions for each treatment were as follows: soaking seeds at 60℃ for 30 min, soaking seeds at 80℃ for 2 min and storing seeds at -20℃ for 7 days. Finally, the best conditions for hard seed breaking were compared among the three treatments, considering the actual planting situation and the best effect of hard seed breaking, it is more appropriate to soak seeds with high hard seed rate at 60℃ for 30 min.

Key words: snap bean seed, hard seed, hard seed breaking, seed soaked in warm water, seed soaked in hot water, low temperature storage
