摘要: 通过研究不同浓度铅胁迫对糯玉米叶片叶绿素含量和抗氧化酶活性的影响,结果表明:糯玉米幼苗叶片中叶绿素a、叶绿素b及叶绿素(a+b)含量随铅胁迫浓度升高而逐渐降低;超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)活性随铅胁迫浓度的升高呈现先升高后降低的趋势;低浓度铅处理对糯玉米幼苗生长具有一定的刺激作用,而高浓度铅处理对糯玉米幼苗生长则表现为抑制作用。

关键词: 糯玉米, 铅胁迫, 抗氧化酶

Abstract: We studied the effects of lead stress on chlorophyll content and the activity of antioxidant enzymes in waxy corn seedling leaves. The experiment results showed that with the increase of lead concentration the contents of chlorophyll a,chlorophyll b,and total chlorophyll decreased in waxy corn leaves; and the activities of SOD,POD,CAT first increased then decreased; The treatment of low concentrtion lead stimulated the growth of waxy corn,however the treatment of high concentration lead hold it.

Key words: Waxy corn, Lead stress, Antioxidant enzyme
