华北落叶松铜、钼元素含量及抗坏血酸氧化酶活性

The cycle of nutrient elements of Cuprum and Molybedenum and ascorbic acid Oxidase's activities of Larix Principis-rupprechtil Mary

本文对华北落叶松Ｃｕ、Ｍｏ元素含量及抗坏血酸氧化酶活性进行了研究，结果表明：（１）林木各器官Ｃｕ、Ｍｏ元素含量差异较大，不同季节、不同器官中Ｃｕ、Ｍｏ元素含量差异明显。Ｃｕ、Ｍｏ有提高生长部位活动能力的作用。（２）不同季节、不同器官抗坏血氧化酶含量和活力差异极为显著，不同季节、不同器官抗坏血酶氧化酶活力大小排序规律各不相同。

The aim of this article is studying not only the cycles of nutrient elements of Cuprum(copper)and Molybedenum but also the activity of ascorbic acid oxidase.It shows that Cuorum and molybedenum can regulate the acting of growing porting of Larch, Secondly, different organs of Larch have different Cuprum, Molybedenum contents and ascorbic acid oxidase activities. Thirdly,in different seasons,the quantities of Coprum,Molybedenum and ascorbic acid oxidase exsisted in different organs of Larch chang much. Then the organ's arranging order is not the same according to experimental results.
