| 摘 要： | 以枣树幼苗为试验材料,研究模拟高温胁迫对其叶片电解质渗透率、丙二醛和叶片相对含水量(RWC)的影响。结果表明:高温胁迫对枣树幼苗叶片相对含水量的影响并不显著;高温胁迫下,叶片的电解质渗透率有上升的趋势,且胁迫时间越久,电解质渗透率上升的越高;叶片内丙二醛的变化趋势与电解质渗透率的变化趋势相似,胁迫时间越久,胁迫温度越高,丙二醛的含量越高。

| Abstract: | Experimental material was Jujube seedlings, the impact of heat stress on RWC,Electrolyte leakage and MDA were analyzed. The results showed that heat stress had no significant effect on RWC;electrolyte leakage of heat stress had upward trend, the longer high temperature stress, the higher electrolyte leakage;MDA and electrolyte leakage was similar, the longer and higher temperature stress, the higher content MDA. |

| Keywords: | heat stress RWC MDA electrolyte leakage |
