【摘要】 [目的]探讨过氧化氢处理对绿把2号茄子种子萌发的影响。[方法]将供试种子经20%、40%、60%和80%浓度的过氧化氢溶液中分别浸泡2、5和10 min后,进行发芽试验,计算发芽率以及达到最高发芽率所需的时间,比较不同浓度过氧化氢溶液浸种不同时间对绿把2号茄子种子萌发的影响。[结果]低浓度(20%)过氧化氢处理短时间(2和5 min)可以使绿把2号茄子种子萌发提前,并缩短达到最大发芽率的时间。高浓度(60%和80%)过氧化氢处理长时间(10 min)会产生明显药害,延迟萌发,降低发芽率。[结论]该研究为茄子农业生产实践提供参考依据。更多还原

【Abstract】 [Objective] This study aimed to investigate the effect of hydrogen peroxide on the seed germination of eggplant(Solanum melongena L.) Luba 2. [Method] The seeds of Luba 2 were separately soaked in 20%, 40%, 60% and 80% hydrogen peroxide solution for 2, 5 and 10 min before seed germination. The germination rate and days to reach the maximum germination rate were calculated. [Result] Treatment with low concentrations(20%) of hydrogen peroxide for 2 and 5 min made eggplant Luba 2 germinate in advance, and shortened the time to reach the maximum germination rate. Treatment with high concentrations(60% and 80%) of hydrogen peroxide solution for longer time(10 min) caused significant damage to the seeds, delayed seed germination, and reduced the germination rate. [Conclusion]This study will provide theoretical references for the production practices of eggplant.更多还原
