黄瓜耐热材料筛选

Selection of heat tolerant germplasm in cucumber

为了获得黄瓜耐热性材料,以所收集的生态型不同的黄瓜品种为试材,经田间自然高温幼苗期与成株期耐热性筛选,结合人工高温幼苗耐热性筛选,结果获得耐热黄瓜材料6个,热敏黄瓜材料2个,丰富了黄瓜耐热性与热害研究的材料,有助于解决黄瓜生产中的热害问题。

In order to select heat tolerant cucumber,we had compared heat tolerance of different ecotype cucumbers in the field and at seedling stage under 42℃ for 24 h. The results showed that six cultivars were heat tolerant and two cultivars were heat sensitive. The tests found materials for study heat tolerance and heat injury in cucumber. This discovery will play a role in finding a genetic solution for heat injury problem in cucumber production.
