| 摘 要： | 研究了不同氮素施用量对桃树叶的细胞构造和碳水化合物含量的影响，结果表明：叶内氮素含量（干物重％）、叶面积、全叶绿素含量随氮素施用量的增加而增加，淀粉含量随氮素施用量的增加而降低，全糖含量随氮素施肥量的增加而增加，山梨醇（Ｓｏｒｂｉｔｏｌ）含量在Ｎ－０区上最低，其他处理没有差异。

Changes of Starch in Leaves of Peach Trees Grown after\;the Application of Different Amounts of Nitrogen |

| Abstract: | The effects of the application of different amounts of nitrogen on the accumul ation of nonstructural carbohydrate,as well as on some characteristics of leaves,were determined for young peach trees.The influence of nitrogen fertilization on cellular structure and carbohydrate contents were investigated.With increase in fertilization of nitrogen concentration,the contents of nitrogen(Percentage of dry matter weight).total chlorophyll and total sugar in leave inceased,leaf expanded, but starch content decreased.Sorbitol content was lowest without nitrogen (N 0 treatment) and was not different at the other treating concentrations. |
