摘要
将17份黄瓜种质材料的幼苗叶片放入50℃水浴中热处理15 min后,采用电导法测定叶片的伤害度(ID值),并结合夏季田间主要经济性状调查结果进行耐热性比较,结果显示黄瓜幼苗叶片的伤害度与始雌花节位、第一坐果节位及产量显著相关,从中筛选出07-5、614、Y5、07-1等4份黄瓜耐热种质材料。
The electrical conductivities and injury degrees (ID) in 15 min under 50℃ of seventeen cucumber species were determined. Compare ID in 15 min with the field research data of plants in summer, there were significant correlation between ID in 15 min under 50℃ and the nodal position for first female flower bud, the nodal position for first fruit, per mu yield. The results showed that four cuhivars were heat tolerant.
