叶绿素的

Light response curve of photosynthesis and some parameters of chlorophyll fluorescence in these species were determined.

分别将马尾松、黧蒴、荷木、黄果厚壳桂的幼苗置于100％自然光和32％自然光下生长6个月，测定它们的光强-光合反应曲线和叶绿素荧光的某些参数。

The chlorophylls are modified tetraphyrroles containing magnesium that occur as light –harvesting and reaction center pigments of photosynthesis in plants ,algae and photosynthetic.

叶绿素是修饰过的含镁四吡咯，它是植物藻类和光合作用中的捕光色素和反应中心的色素。

Zn~(2+) had a relative lower toxic effect on the conchocelis among the five heavy metal ions in this experiment, when the concentration was up to 60μmol/L and time was after 48 hours, its slightly negative effect on the conchocelis came into effect, chlorophyll a content, soluble protein content, mannite content, POD activity started to decrease and MDA content began to increase.

Zn~(2+)在实验所采用的五种重金属离子中毒性较弱，对藻体造成的抑制影响较小，当浓度升至3.9mg/L、时间加长到48h时出现极微的抑制作用，叶绿素a含量、可溶性蛋白含量、甘露醇含量、POD活性下降，丙二醛含量升高。

But the total chloroplast plan area per mesophyll cell was conserved in sense, antisense and wild type tobaccos.

同时还证明NtFtsZ2-1基因表达的变化对叶绿素含量和叶绿体的光合作用能力没有直接的影响。

C〓 alkylthiophene from aromatic fraction of pyrolysates at 200℃ probably originated from the combination of phytol group of chlorophyll and organic surphur of algal cells.

盘星藻200℃热解产物芳烃组分中的C〓烷基噻吩可能是来源于叶绿素类的植醇基与来源于藻类体内的有机硫结合而形成。

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 contents of chlorophyll and soluble protein decreased continuously in both CMS and their maintainer; while the contents of soluble sugar, praline and the activities of three protective enzymes at first increased, then decreased under cold-stress.

随着低温处理时间的延长，不育系和保持系叶绿素和可溶性蛋白质含量一直下降，可溶性糖和脯氨酸含量呈现先上升后下降的趋势；SOD、POD和CAT活性呈现先上升后下降的趋势。

It is favorable on the increase of leaf chlorophyll content,accumulation of day matter and WUE of cucumber under the proper irrigation frequency under drip irrigation manner and irrigation frequency six day.

适宜的灌溉频率也即是在滴灌条件下灌溉频率为6天对于增加叶片的叶绿素含量、干物质积累和水分利用率是有利的。

The experimental results indicated that, after chilling treatments, chlorophyll a fluorescence induction kinetic curves of tomato leaves were changed obviously,the Fv/Fo and Rfd values were decreased,and the primary light energy conversion of photosystem II and the potential photosynthetic activity had been inhibited.

实验结果指出，在低温处理(8℃，5℃，2℃下，暗中24小时)后，番茄叶片的体内叶绿素a荧光诱导动力学曲线有了明显的改变，Fv／Fo值、Rfd值降低了，光系统II原初光能转换效率和潜在的光合活力均受到抑制。

The effect of treatment content of MDA with rhizobium alone is always higher than that of CK at different growth stages in tobacco root ,stem and leaf cells, and rhizobium could induce activity of SOD and content of soluble protein to increase in the first and the second week.

在实验中，我们测定了以上四种处理对不同发育周期烟草不同组织来源的超氧化物歧化酶的活性，丙二醛，可溶性蛋白和叶绿素含量以及根尖细胞染色体的影响。

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。
