| 摘 要： | 以2个葡萄品种"贝达"和"赤霞珠"为材料,研究了开花期过后1年生枝条功能叶片光合指标;以及葡萄糖、果糖、淀粉等碳水化合物含量与转化酶和淀粉酶活性的变化与联系。结果表明:开花期过后,"贝达"和"赤霞珠"功能叶片的净光合速率和Rubisco羧化效率呈下降趋势;果糖含量基本不变,葡萄糖、蔗糖及总可溶性糖含量波动上升;中性转化酶活性变化较小,α-淀粉酶和β-淀粉酶活性分别在前期和后期较高。"贝达"和"赤霞珠"功能叶片的Rubisco羧化效率与净光合速率呈极显著正相关;与葡萄糖/(果糖+蔗糖)呈显著负相关。在"贝达"和"赤霞珠"功能叶片中葡萄糖含量与β-淀粉酶活性分别表现出极显著和显著的正相关性。推断,开花期后"贝达"和"赤霞珠"功能叶片中葡萄糖的积累可能主要是通过β-淀粉酶代谢途径产生,并对其光合作用产生了反馈抑制的效应。

| Abstract: | Photosynthesis parameters,contents of carbohydrate such as glucose,fructose,and starch,activities of invertase and amylase,along with their relationships were studied in the functional leaves of one-year-old twigs of two grape cultivarsBetaandCabernet Sauvignonafter the flower stage.Results showed that the apparent photosynthesis rate and the Rubisco carboxylation efficiency decreased after the flower period. Meanwhile,the fructose content kept constant but the contents of glucose and sucrose increased with... |
