摘要:: 以萝卜芽苗菜为试材，探讨了在不同浓度铅（100、300、500 mg?L-1）胁迫下，4种内源植物激素（玉米素（ZR）、脱落酸（ABA）、赤霉素（GA3）、吲哚乙酸（IAA））以及IAA/ABA、GA3/ABA的动态变化。结果表明：ZR含量随铅浓度的升高而下降。ABA随着铅浓度的升高呈现出先下降后上升趋势，GA3含量则呈现出先上升后下降的趋势，在铅浓度为300 mg?L-1时达到最大值。IAA与GA3变化趋势保持一致，在铅浓度升高的条件下，含量先升后降，在铅浓度100 mg?L-1时达到峰值；生长促进类激素与衰老促进型激素的比值如IAA/ABA、GA3/ABA也随着铅浓度的升高，呈现出先上升后下降的趋势。表明铅胁迫能改变萝卜芽苗菜内源植物激素含量，进而调控萝卜植株的生长。

Abstract:: The dynamic changes of endogenous hormones (ZR，ABA，GA3，IAA，IAA/ABA，GA3/ABA) were detected by taking Raphanus L.seedlings as the material under the different concentration of Pb(100,300,500 mg?L-1) stress.The results showed that ZR content decreased with the increased concentration of Pb.With the increased lead concentration，ABA concentration showed a rising trend after the first fall.GA3 content was showing a downward trend after the first rise，getting the maximum at the lead concentration of 300 mg?L-1.IAA and GA3 contents were consistent in lead concentration conditions，increased and then decreased.IAA content obtained maximum value at 100 mg?L-1 pb concentration.The ratio of growth promoted hormones and aging promoted hormone as IAA/ABA，GA3/ABA showed a downward trend after the first rise with increased concentration of lead，which indicated lead stress could alter the endogenous hormones of Raphanus L.seedlings and then regulate the growth of Raphanus L.seedlings.All results showed that the content of the endogenous hormones could be changed and control their growth in Raphanus L.seedlings under the lead stress.
