| 中文摘要: |
| 采用水培方法研究了不同氮素形态对小麦幼苗叶绿体色素、色素蛋白复合体及希尔反应活性的影响。结果表明，50%硝态氮+50%铵态氮处理时，电泳条带中31～43kD范围内的多肽组分及高分量区属于PSⅠ的多肽组分含量最高，两种氮素形态单独施用时最低；叶片的光吸收能力、叶绿素含量及叶绿体蛋白含量均在氮素形态配比相等时达到最大，两种氮素形态单独施用时最低；希尔反应活性则随着铵态氮比例降低而降低。 |

| Different forms of nitrogen were applied on water-cultivated wheat seedling. The results showed that the amounts of 31～43 kD polypeptides of LHCⅡ and the contents of chlorophyll-protein complexes of PSⅠwere increased to a top rate at 50% NH+4-N+50% NO-3-N, while they reached to the lowest point when used any form of nitrogen separate. The absorption spectra of chloroplast thylakoid-membrane (normal temperature) and the contents of chlorophyll and chlorophyll protein reached to the tiptop at 50% NH+4-N+50% NO-3-N and they reached to the lowest point when used any form of nitrogen separate. The Hill reaction activity decreased as the rate of NH+4-N decreased. |
