叶绿素

Effects of different sun-shading treatments plastid pigment on flue-cured tobacco were researched.

研究了不同遮阳处理对不同生育期及不同部位烟叶叶绿素及类胡萝卜素的含量影响。

A chlorophyll-containing plastid found in algal and green plant cells.

含有叶绿素貌似植物的鞭毛虫；通常被认为是单细胞藻类。

A plastid that contains pigments other than chlorophyll, usually yellow or orange carotenoids.

有色体，色素体除了叶绿素外的含色素的质粒，通常为黄色或橙色的类胡萝卜素

The main results were as follows:An appropriate concentration of ethephon sprayed on leaves of peanut made stems and branchs height shorter,but more branches;The fresh weight and dry weight per unit of leaf area and per plant increased;It optimized some physiological and biochemical characteristics in the leaves.It was showed that the ethephon increased obviously the contents of protein and chlorophyll and the activity of SOD and POD in the leaves,and improved the rates of photosynthesis and transpiration of the leaves,and increased the activity of the roots,but decreased the content of MDA in the leaves;It improved the quantity of pods,the percentage of plumy pods and the peanut yield.

结果表明：喷施适宜浓度的乙烯利可使植株相对矮化，抑制花生地上部分的生长，使主茎和分枝长比对照短，但分枝数较多；提高单位叶面积鲜重、干重以及植株鲜重、干重；优化花生植株的生理生化特性，表现为显著提高了花生叶片的蛋白质含量和叶绿素含量及SOD和POD活性，增强了花生叶片的光合速率和蒸腾速率，增强了主根活力，降低了花生叶片的丙二醛和可溶性糖含量；提高植株的单株结荚数、饱果率和产量。

The paper mainly studied the effects of different concentration of Cd single and Cd+Se 0.05 mmolL^(-1 combined pollution on dynamics of chlorophyll, proline, malondialdehyde and SOD, POD, CAT in corn seedling using the solution culture method.

采用溶液培养法，在不同浓度Cd单一及Cd+Se复合污染下，对玉米体内叶绿素、脯氨酸、丙二醛，以及对超氧化物歧化酶、过氧化物酶、过氧化氢酶活性的动态变化进行测定。

This study indicated that the genes which control the whole chlorophyll contents are additive-dominanceepitasis and most are min-effect polygene,so this is affected by environment easily,does not fit to the earlier choice.

研究结果表明，控制黄瓜总叶绿素含量性状基因间为加性-显性-上位性作用，以微效多基因为主，受环境影响较大，不宜进行早代选择。

On Cd-contaminated soil the use of organic fertilizer could stimulate the output, the chlorophyll content and protein content of potherb mustard.

在Cd污染土壤上，施用有机肥可以提高雪里蕻的产量、叶绿素含量和蛋白质含量。

On Pb-contaminated soil, the use of organic fertilizer could stimulate the output, the chlorophyll content, the protein content and activity of enzyme of potherb mustard.

在Pb污染的土壤上，施用有机肥能提高雪里蕻产量、叶绿素含量、蛋白质含量和酶活性。

As material, The changes of the contents of chlorophylls, MDA, praline and the activity of SOD of I. pseudacorus L. leaves were studied with different Pb concentration and different treatment time by sand culture. The results showed that the contents of chlorophylls in the leaves of I.

为材料，采用沙培方法，对不同Pb浓度(0、2、4、6、8、10mmol/L)和处理时间(7、14、21、28d)胁迫下植物的叶片叶绿素、丙二醛和脯氨酸含量以及超氧化物歧化酶活性的变化进行了研究。

Effects of Cr(superscript 3+) with different concentration on content of chlorophyll, root top ratio, content of praline and root activies in radish seedlings were studied by the method of sand-culture.

采用砂培研究了萝卜幼苗受到Cr(上标 3+)胁迫时，根冠比、根系活力、叶绿素含量和植株体内脯氨酸含量的变化。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
