叶绿素

Other chemicals,3-PGA,3-GAP,HPMS,DCMU,DBMm, Ant A and gramicidin D all showed an inhibitory efect on PSII photochemical activity (expressed by chlorophyll fluorescence parameters)and electron transport rate of PSII+PSI.

And with decrease in light intensity,the shape of palisade mesophyllchanged from column into invert pyramid.The higher proportion of granum thylakoid,more granum in one ganum thylakoid and lower ratio of chlorophyll a to chlorophyll bwere also the responses of leaves to shading.

在庇荫环境中，栅栏组织薄壁细胞由全光的柱状变成倒锥形、叶绿素a/b率显著降低、叶绿体中基粒类囊体所占的比例提高、每个基粒类囊体垛的片层数量增加等，也是幼树提高叶片对弱光利用能力的主要标志。

It may be coloured with chlorophyll or not more than0.015% of a suitable green soap dye.

它可能由叶绿素或不多于0.015%合的绿皂染料染色。

One of the tanks held a protein-dextrose-chlorophyll gel, and the other tank held an epoxy-cellulose hardener.

那对容器中的一个装有蛋白质-葡萄糖-叶绿素胶体，另一个装有环氧-纤维素硬化剂。

With American head lettuce as tested material, the rectangular hydroponic mode with gas-charged static nutrient solution was adopted, 6 different formula treatments including NO3(superscript -):NH4(superscript +)=80:20, 70:30, 60:40, 50:50; NO3(superscript -) replaced by CO (NH2) 2 as well as CK were set up and each formula was prepared by using groundwater directly to study the effects of different substitution amounts of nitrate nitrogen on growth status, root activity and chlorophyll content of lettuce.

方法］以美国结球生菜为试材，采用充气式静止营养液矩形水培方式，设定NO3：NH4=80：20，70：30，60：40，50：50；CO(NH2)2代替NO3以及对照共计6种不同的配方处理，各配方直接利用地下水进行配制，研究硝态氮不同替代量对生菜生长状况、根系活力和叶绿素含量的影响。

Methods Pot experiments were carried out to study the effects of the seawater on photosynthesis and chlorophyll Ⅱ fluorescence of Helianthus tuberosus seedlings from three different regions, Yancheng, Wuwei, and Yantai.

该研究以不同产地菊芋为试验材料研究了海水处理对菊芋幼苗生长、光合作用和叶绿素荧光特性的影响。

Porphyrins and metalloporphyrins are important life-substance, existing in vivoextensively, which are key structures of chlorophylls, hemachrome, vitamin 〓,hemoglobin, etc.

卟啉及其金属络合物是一种具有多种功能的生命物质，广泛存在于生物体内，是重要生命物质如叶绿素、血红素、维生素〓、血红蛋白等化合物的关键结构。

This is the web page of Heme, Chlorophyll, and Bilins.

这是亚铁血红素，叶绿素，与三烯胆色素核的网页。

It implied that the moderate shading could improve contents of chlorophyll, and delay mature stage and florescence. This was important for the growth and garden applications of Hemerocallis fulva var. florepleno.

适度的遮荫可以提高重瓣大花萱草的叶绿素含量，对延缓叶片的成熟期和花期有重要的影响，同时对重瓣大花萱草的生长及园林应用有重要意义。

The photosynthetic pigment contents, chlorophyll a/b rate, free proline, soluble sugar and malondialdehyde contents in the leaves of Hemerocallis fulva var. florepleno which was under different light intensities during their growth were studied.

对重瓣大花萱草进行不同程度遮荫处理，研究了其生长过程中叶片中的光合色素含量、叶绿素a/b值、游离脯氨酸、可溶性糖及丙二醛含量的变化及其生理特性。

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。
