锌铬复合胁迫对水稻植株碳氮代谢的影响
- Title:
- Effects of Compound Stresses of Zn and Cr on Carbon and Nitrogen Metabolisms of Rice Plant

- 摘要:
- 通过盆栽试验，研究了锌铬复合胁迫对水稻植株碳氮代谢的影响。结果表明，在锌铬复合胁迫下，随着土壤中锌、铬浓度的增加，水稻干物质积累量降低，根冠比及根系可溶性糖含量呈增加的趋势，而茎鞘及叶中可溶性糖含量呈降低的趋势；根系、茎鞘及叶中可溶性蛋白含量和全氮含量则呈高低起伏的变化。偏相关分析表明，土壤中锌、铬浓度与水稻根系、茎鞘及叶中可溶性糖含量，水稻根系可溶性蛋白含量均产生了Zn-Cr协同效应，而与全氮含量未产生复合效应。这说明在重金属胁迫下，水稻通过协调自身源流库的关系，提高其对逆境的生态适应能力。
- Abstract:
- The effects of compound stresses of Zn and Cr on carbon and nitrogen metabolisms of rice plant were investigated in a soil pot experiment at tillering stage. The results showed as follows:with increasing of concentrations of Zn and Cr, the biomass of rice plant had a trend to reduce, and the ratio of root/shoot and soluble carbohydrate content of rice roots had an increasing trend, but soluble carbohydrate content of stem and sheath and leave reduced, and soluble protein and total nitrogen contents of roots, stem and sheath and leave changed wavely. Partial correlation analysis showed that concentrations of Zn and Cr in the soil had synergy effect on soluble carbohydrate content of roots, stem and sheath and leave, and soluble nitrogen content of roots. There was no compound effect on total nitrogen of rice plant. Those explained that rice plant adjusted the relationship between source and library to enhance its ability of ecological adaptation under the heavy metals stresses.
