| 摘 要： | 本试验探讨了不同浓度多效唑(PP333)对琯溪蜜抽枝梢生长和越冬期叶片淀粉、可溶性糖含量、束缚水/自由水比值的影响.结果表明,多效唑处理能提高越冬期叶片可溶性糖含量,增大束缚水/自由水比值,降低淀粉含量;多效唑处理使新梢长度、节间长度明显受抑制,新梢粗度增加,且随着使用浓度的增大作用增强.

| Abstract: | The effects of PP333 solution at different concentrations on the shoot growth, contents of starch and soluble sugar and ratio of bound water to free water in leaves of Guanxi honey pomelo trees during wintering season were studied. The results showed that the treatment of PP333 improved the content of soluble sugar, increased the bound water/free water ratio and decreased the content of starch in leaves of pomelo trees during wintering season; the treatment. significantly inhabited the length of shoots and internodes and increased the diameter of shoots with the concentrations of PP333. |
