| 摘 要： | 以豌豆(Pisum sativum L.)为材料,研究了铬对水培豌豆的胁迫作用及壳聚糖(chitosan,CTS)对铬胁迫的缓解效应。结果表明:0～200 mg.L-1铬胁迫浓度范围内,随铬胁迫浓度的增加,豌豆种子的发芽率、发芽指数和活力指数等下降,下胚轴丙二醛含量和相对电导率增加;显著抑制豌豆种子萌发的铬胁迫浓度为100mg.L-1,极显著抑制豌豆种子萌发的铬胁迫浓度为200 mg.L-1。0.5%壳聚糖可缓解铬对豌豆种子萌发的毒性。

| Abstract: | The role of Chromium stress on hydroponic peas(Pisum sativum L.) and effects of Chitosan(CTS) on peas under the chromium stress were studied.The results showed that germination rate,germination index and vigor index of pea seed decreased,MDA content and relative electrical conductivity of hypocotyls increased with the increase of the concentration of chromium stress in range of 0-200mg·L-1.The germination of pea was significantly inhibited when the concentration of Chromium was 100mg·L-1.The germination of pea was very significantly inhibited when he concentration of chromium was 200mg·L-1.0.5% Chitosan could alleviate the toxicity of the chromium stress. |
