| 摘 要： | 摘要：【研究目的】阐明在污染条件下小麦对重金属胁迫的反应,为农田小麦重金属污染的监测和综合治理提供理论依据。【方法】根据等毒性原理设计，对小麦幼苗施以0.25mM 铬、0.8mM 铅单一及其复合污染胁迫。【结果】引起叶绿素含量减少，气孔阻力增大，叶片渗透势下降，根与叶组织质膜透性变大，叶片可溶性蛋白质含量减少，同时，0.25mM铬或0.8mM 铅胁迫造成根系活力下降。【结论】叶绿素含量和组织电导率对复合污染胁迫更敏感，是复合污染胁迫监测的首选指标。 |

| Abstract: | The coexisting and independent stress effects were studied of two heavy metals of Cr and Pb on the physiological and biochemical characters of wheat seedlings. The results showed that: stresses of 0.25 mmol/L Cr or 0.8 mmol/L Pb resulted in that wheat chlorophyll content and soluble protein content went down, stomatal resistance up, leaf osmotic potential down, root and leaf solute leakage up. However, Cr or Pb caused root vigor to go down. chlorophyll content and conductivity were first index which is more... |
