| 摘 要： | 用石至石进行番红花盆栽试验,观察到低钾水平(1mg/L)下,膜脂过氧化作用明显加强,MDA增加349%,导致膜伤害,膜相对透性增加648%.其原因是低钾条件下,SOD,CAT,POX等膜保护酶活性分别降低639%,588%,696%,活性氧代谢平衡失调所致

| Abstract: | The pot experimant of Crocus Sativus L.was carried on with vermiculite.It was observed that the level of peroxidation of mombrane\|lipids energized significantly urder low k level.And MDA increased 34\^9% which caused the membrane injury.The relative membrane permeability increased 64\^8%.The cause was that the activities of ceifensive enzymes SOD,CAT,POX decreased separately 63\^9%,58\^8%,69\^6% under low K condition,which was cause by avidity peroxide of metabolism unbalance. |
