| 摘 要： | 对2个耐热性不同的水稻品系进行高温处理（8:00~17:00, 37℃; 17:00~8:00, 30℃）, 测定了高温胁迫对水稻剑叶中保护酶类活性和膜透性的影响。结果表明，水稻剑叶中超氧化物歧化酶（SOD）、过氧化氢酶（CAT）、过氧化物酶（POX）和抗坏血酸过氧化物酶（AsA-POX）活性在高温胁迫初期均有明显增加，尔后快速下降, 耐热品系996这

| Abstract: | High temperature is a key factor during rice heading and flowering period affecting seed set rate and grain yield in main production areas of China, but the physiological mechanism was related to high temperature stress remains unclear. The experiments were carried out in growth chambers to investig |
