| 摘 要： | 以"贝达"和"赤霞珠"葡萄品种1 a生开花枝条功能叶片为材料,研究其开花后叶片碳氮代谢特性。结果表明:"贝达"与"赤霞珠"1 a生开花枝条功能叶片的硝态氮含量均呈先升高后降低的趋势,氨基酸氮含量则呈现先降低后升高的趋势,硝态氮含量与氨基酸氮含量呈显著负相关;贝达NR活性与氨基酸氮积累量变化较一致,而GS活性较平稳;赤霞珠NR活性最低值出现在花后45 d左右,而氨基酸氮含量在花后75 d时降至最低值;2个葡萄品种总碳含量和总氮含量均在中期最高,其硝态氮在中期积累,而氨基酸氮中期下降。

| Abstract: | Taking functional leaves from one-year-old twigs of two grape cultivars Beta and Cabernet Sauvignon as materials,the carbon and nitrogen metabolism of leaves from these two grape cultivars were studied.The results showed that the nitrate nitrogen content of functional leaves from one-year-old twigs of Beta and Cabernet Sauvignon increased firstly,then decreased,on the contrary,the amino acid nitrogen content decreased firstly then increased,nitrate nitrogen content were negatively correlated to amino acid n... |
