类叶绿素

Sulfur can promote the formation of chlorophyll; sulfur involved in the process of nitrogen fixation, to increase the utilization rate of fertilizer; in cruciferous rape, peanuts propylene mustard oil, Liliaceae onions and garlic contained in Suanyou fat, such as sulfur compounds in human nutrition and medicine There are special effects to enhance the quality of these crops.

硫能促进叶绿素的形成；硫参与固氮过程，提高肥料利用率；十字花科中油菜、花生的丙烯芥子油，百合科葱、蒜中所含的蒜油等硫脂化合物在人体营养和医药方面有特殊的功效，提高这类作物的品质。

Influences of two temperatures (4 and 20℃) on weight loss, carotenoids andGS contents in pakchoi shoots were investigated during storage.

5研究了不同贮藏温度(20℃，常温；4℃，低温)对小白菜失重率、叶绿素、类胡萝卜素和硫代葡萄糖苷含量的影响。

The seasonal variation of the content of chlorophyll and carbohydrate in Photinia×frasery"Red Robin"leaves was consistent,showed decrease-increase-decrease curve,the max presented on July and August respectively.

叶片中叶绿素和类胡萝卜素含量的季节变化趋势基本一致，呈下降-上升-下降的趋势，分别在7月和8月份达到最大值。

SPAD values of relative chlorophyll in CK were significantly lower than in Mo application in 34 winter wheat cultivars.

缺钼时类胡萝卜素含量同叶绿素含量一样显著下降，并与之在不同时期呈现一致的变化趋势。

The yellow colour seen in some autumn trees results from the loss of chlorophyll simply unmasking the yellow carotinoids that were there all along.

部分树木的叶子在秋天里变成黄色，这是因为叶绿素的分解让黄色的类胡萝卜素暴露出来。

In this study, an oilseed rape mutant type Cr3529 was chosen to be the material to study the developmental characters of chloroplasts in etiolated mutant type.

本论文以油菜黄化突变体Cr3529为材料，研究了不同生长时期不同器官的基因表达、色素蛋白含量、叶绿素光谱吸收、LHCII的蛋白含量及组成、类囊体膜的室温荧光光谱、CD谱、DCIP活性和多聚核糖体等。

So it is significant by providing government with evidence to establish the policy and law.At the aspect of maize morphology, enhanced UV-B radiation reduces plant height and leaf area, slenderizes leaves, and reduces the weight proportion of seeds to leaves, seeds to cornstalks and roots to canopy.

UV-B增加对玉米形态学上的影响包括株高降低、叶面积下降、叶片变狭长、玉米粒叶比、粒秆比、根冠比均减小；对生理生化的影响包括叶片中的类黄酮及可溶性蛋白含量增加、叶绿素含量降低。

Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是：藻体为单细胞或连成各式群体；细胞壁由硅质和果胶质组成，而且在结构上都是由上壳和下壳套合而成，纵断面观呈&肥皂盒&形；在上下壳的壳面上有花纹，花纹排列的方式主要分为两侧对称和辐射对称两大类，为分类上的最重要依据；能运动的种类在壳面都有壳缝，不能动的种类均无壳缝；色素体片状或带状，1个或2个，或为多个小盘状，黄绿色或黄褐色，含叶绿素a、c，还含有墨角藻黄素和硅甲黄素等光合色素；贮藏物质主要为油滴；繁殖方式主要为细胞分裂，硅藻的细胞分裂的明显特点是：每次细胞分裂所产生的2个子细胞中，仅有1个和母细胞等大，另1个则稍小。

When oxygen is present in cells, polyphenol oxidase enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.

当氧存在于苹果组织的细胞中时，叶绿体（含有叶绿素和进行光合作用的地方）中的多酚氧化酶，会迅速地将天然存在于苹果组织中的酚类化合物氧化为邻醌。

Protoporphyrinogen oxidase inhibiting herbicide is becoming a hot point of novel herbicide development because it inhibits the enzyme catalysing the synthesis of chlorophyl in plant cell, insures the different activity between plants and animals, and has the virtues of high effectivity, low toxicity and mezzo residue.

而原卟啉原氧化酶抑制剂类除草剂以植物细胞中催化叶绿素合成的酶为作用点，确保了动植物之间的选择毒性，具有高效、低毒、残效适中的特点，成为新型除草剂开发的热点。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
