| 摘 要： | 利用高温(40～50 ℃) 预先对黄瓜幼苗处理1～2 h , 可以不同程度地诱导黄瓜苗对黑星病(Cladosporium cucumerinum Ell. and Arth. ) 的抗性, 40 ℃2 h、45 ℃1 h 高温诱导抗病性表达明显。高温热击后4 h 即开始表现出诱导抗病性, 24 h 诱导抗病性表现最明显。通过对18 个黄瓜品种的高温热击试验发现, 不同黄瓜品种经高温热击处理后表现出的诱导抗病效果不同, 有些品种在40 ℃2 h、45 ℃1 h 处理下诱导效果均较明显, 有些品种在40 ℃2 h 处理下诱导效果明显, 而有些品种则在45 ℃1 h 处理下诱导效果较好, 还有些品种高温处理后无效果。

| Abstract: | High temperature(40-50℃)for 1-2 hours induced resist ance to the scab pathogen，Cladosporium cucumerinum in cucumber plants.The h igh temperatures of 40℃ 2 hours or 45℃ 1 hour was found to be the optimal trea tment for the induction of resistance.Plants inoculated with C. cucumerinum just at the time of 4 hours after heat shock of high tempe rature exhibited increased resistance to the fungus.A 24 hours interval f rom heat shock of high temperature to inoculation allowed for development of max imum resistance.Eighteen cultivars were tested by heat shock of high temperature ，and it was found that different cultivars expressed distinct induction resista nce to C.cucumerinum.Some cultivars exhibited induced resistance in the trea tments of 40℃ 2 hours and 45℃ 1 hour.Some cultivars exhibited induced resistan ce in only one of the two treatments，while others had no expression of induced resistance. |
