| 摘 要： | 试验研究重金属Cd、Zn胁迫对水培番茄种子萌发、幼苗生长及相关生理指标的影响结果表明,Cd、Zn明显抑制番茄种子的发芽势和根的伸长、幼苗株高和干物质积累,而对种子发芽率的影响则较小;番茄叶片叶绿素含量和a/b值减小,高浓度处理时茎和叶片中含水量明显降低,可溶性糖、脯氨酸和谷胱甘肽含量增加,且叶片含量均高于根系。

| Abstract: | An experiment was carried out to evaluate the effects of various cadmium and zinc stress on the germination,growth and correlatively physiological indicators of tomato seedlings.The results show that the cadmium and zinc remarkably inhibite the sprouting potential and the root elongation,but sprouting ratio is affected little.The plant height,biomass accumulation,water content of leaves and stem,chlorophyll content and chlorophyll a/b ratio are decreased.The contents of soluble sugar,proline and GSH are increased and those contents in leaves are higher than those in roots. |
