叶绿素酶

The result also show that:mycorrhiza' s promotion to Populus ussuriensis seedlings ' growth is directly related to the improve ment of inoculated seedlings' chlorophyll content and enzyme activity.

结果还表明，菌根的促生长效应与菌根化苗木的叶绿素含量的增加及过氧化氢酶活性的提高呈正相关。

The contents of chlorophyll and the catalase activity of celery were increased 19.06%, 6.52% in the once top-dressing treatment with 300ml biogas slurry (A1I) than that applied chemical fertilizer (A1I).

其中一次施用300ml沼液的追肥处理(A1I)比化肥处理（B1I）对芹菜的叶绿素含量、过氧化氢酶活性分别提高了19.06%、6.52%；一次施用900ml沼液的追肥处理(A2I)比化肥处理（B2I）对芹菜的VC含量、还原糖含量分别提高了9.07%、51.31%，硝酸盐含量下降了31.65%；且施用沼液时一次施用与分次施用对芹菜的品质、产量无显著影响，化肥的分次施用与化肥的一次施用相比，芹菜的硝酸盐含量显著降低。

4 Mechanisms of the effects on yield and quality With the application of nitrogen, the chlorophyll content, NRase activity, photosynthesis rate, fluorescence parameters in the ear leaves of spring-sown maize and summer-sown maize were affected dramatically, which could affect the yield and quality of maize.

3.4 不同施氮水平产量和品质差异的生理学基础春夏玉米套作时，施氮处理显著影响春、夏玉米穗位叶叶绿素含量、硝酸还原酶活性、光合速率、荧光参数等，从而影响产量和品质。

The results showed that compared with flat planting,the leaf area, flag leaf function duration, chlorophyll content and the activities of protection enzymes of SOD, POD and CAT in leaves in straw mulching were significantly higher, its malondialdehyde content and over oxidation degree of membrane lipids was lower, the speed of flag leaf aging was slower and the metabolizability was vigorous, which are beneficial to the grain-filling and accumulation of photosynthesis products.

结果表明，覆草栽培叶面积、旗叶功能期、叶绿素含量、叶片保护酶活性(SOD、POD、CAT)显著高于常规栽培，膜脂过氧化程度较低，叶片衰老速度缓慢，代谢强度旺盛，有利于籽粒灌浆和光合产物的积累。

After seedling trees of Yunhe Snow Pear were polluted by Pb(superscript 2+), Cd(superscript 2+), synthesis of chlorophyll was restrained, toxic effect of Pb(superscript 2+), Cd(superscript 2+) on seedling trees was intensified, membrane lipid peroxidation damage was increased. And the protective enzymes system start-up of polluted seedling trees enhanced antioxidative enzymes activities of seedling trees.

结论］Pb(上标 2+)、Cd(上标 2+)污染云和雪梨苗，抑制叶绿素的合成，增强超养阴离子自由基O2(上标-对植株的毒害性，使膜脂过氧化损伤程度高，受重金属污染植株启动保护酶系统，以增强植株的抗氧化性。
