| 摘 要： | 研究了桃和袖离休叶片在高温胁迫下细胞膜透性（电解质渗漏和Pi渗漏）和光合色素的变化及其与抗热性的关系。结果表明。①高温处理下，无论是黑暗条件下浸水24h，还是光照条件下浸水24h，两种果树的电解质和Pi渗漏都显著增加，光照有利于膜的修复；②高温引起Chl含量下降，Chla／b比值上升；③上述这些生理反应与果树的抗热性有关，可用于果树的抗热性鉴定。

| Abstract: | The effect of high temperature stress on cell membrane permeability (electrolyte leakages and Pi leakages) and photosynthetic pigment in leaf discs of peach andpomelo and their relations to heat-resistance were studied. The results showed that: OHigh temperature stress induced an increase in the leakage of electrolyte and Pi of theleaf discs dipped in distilled water for 24 h,exposed to light or dark at room temperature, and lightness was advantage to membrane repair. @High temperature stress induced a decrease in Chl content and an increase in Chl a/b ratio in leaf discs of peach andpomelo. @The physiological responses above mentioned correlated well with speciesheat-resistance and may be used as screening indexes. |
