| 中文摘要 |
| 报道钙对酸雨胁迫下甜瓜幼苗质膜透性的影响。实验结果表明,钙可明显降低质膜透性,具有防护质膜酸致损伤的良好作用。在本实验条件下,以30mmol/LCa(NO3)2连续处理2次(24h1次)的防护作用最佳。可能与钙能稳定质膜结构,提高CAT活力等多重生理作用有关。 |
| 英文摘要 |
| The relationship of calcium to cell membrane permeability in acid rain stressed Cucumis melo seedling has been studied. Calcium obviously decreased cell membrane permeability and protected cell membrane from acid rain insult.Optimum protection effect is that Cucumis melo seedling is spraied continuously two times(once every 24 hours)with concentration of 30mmol/L Ca(NO3)2 at the test conditions. The mechanism perhaps is calcium reagent stabilizing the structure of cell membrane of Cucumis melo and raising catalase activity. |
