| 摘 要： | 对豫楸1号扦插生根过程中营养物质（总糖、全氮、总糖/全氮）含量变化进行了研究．结果表明：豫楸1号催芽抽生嫩枝插穗中的可溶性蛋白含量在扦插阶段前期急剧下降．之后趋于平缓，总糖含量一直处于缓慢上升趋势，全氮在扦插期间变化不大，总糖／全氮值变化趋势与总糖有相同的变化趋势。

| Abstract: | The article studied the changes of nutrients(total sugar,total nitrogen,total sugar/total N) of Catalpa bungei cl.‘Yu-1’ in the root-cuttings process.The results showed that: The soluble protein of the forcedsprouting cuttings decreased dramatically in prophase,and then the decrease tended to slow.The total sugar content always raised slowly.The total nitrogen had a little change.The total sugar/total nitrogen had same trends with total sugar. |
