At the same time, the concentration of chlorophyl a and b increase significantly in the leaves of Broussonetia papyrifera seedlings.
在混合接种下表现出较单独接种更大的生物量促进效应，而单独接种中又以透光球囊霉接种效果最明显。
The Value of Ci of leaf in Rain cultivation is less than in Open-air cultivation. The content of chlorophyl a and b of Rosario Bianco leaf in Rain cultivation is higher than in Open-air cultivation and the chlorophyl content of the 5th leaf is maximal in Rain cultivation. Stem diameter of Rosario Bianco were increased 8.68%~10.74% during the stage of rain growth in Rain cultivation. The study shows the leaf area of Rosario Bianco in greenhouse is lager than unsheltered and the environment of greenhouse is suit for grape leaf growing.
避雨棚对葡萄叶片的胞间二氧化碳浓度有抑制作用；避雨棚对`白罗莎里奥`叶片叶绿素a和叶绿素b含量的影响显著：避雨栽培条件0000下叶片的叶绿素均高于露天栽培，叶位5的叶片叶绿素含量最高；避雨栽培模式较露天栽培在避雨阶段葡萄茎粗增加了8.68%~10.74%且避雨栽培可显著增加葡萄叶面积。
Effects of simulated acid rain on content of chlorophyl a, B and their ratio in cotton cotyledon
模拟酸雨对棉花子叶叶绿素a、b含量及其比值的影响
Measurement of chlorophyl a and B by Spectrophotometry
分光光度法同时测定叶绿素a和b的含量
The content of chlorophyl in the leaves of 50% and 30% increased, while the ratio of chlorophyl A and B fell significantly.
30%和50%处理的叶片的叶绿素含量均升高；各处理的叶绿素a/b均显著降低。
