Leaf nitrogen content induces remarkable effect on chlorophyll and soluble protein content.
叶片氮含量对叶绿素与可溶性蛋白含量会产生明显的影响。
With the depth of canopy increases, leaf nitrogen content reduces gradually, thus vertical nitrogen gradient develops.
作物冠层中叶片氮素含量沿冠层从上向下逐渐减少，形成了氮素的垂直分布梯度。
And the results suggested: Machurian Ash seedling leaf nitrogen content is linearly relative to the nitrogen supply levels.
