摘　　要：用25～65℃恒温水浴对黄瓜种子进行热击处理10～40min，结果表明，25℃处理30min到55℃处理30min，随着温度升高种子萌发率增大．黄瓜种子在55℃处理20min后，种子萌芽率显著升高，萌芽指数和活力指数增大，平均萌芽天数缩短，促进幼苗生长．The cucumber seeds were treated with heat shock under the water temperature from 25 to 65℃ for 10--40 minutes. The experimental results during 30 minutes＇ treatment with the temperature increase from 25℃ to 55℃, the germination rate of cucumber seeds also increased. If the seeds were treated for 20 minutes under a water temperature of 55℃, the germination rate would increase considerably, the indexes of germination and vigor would increase as well, with a decrease in the average period of germination and enhancement in the seedling growth.
