Sodium chromium chlorophyllin is soluble in water, stable in the neutral solution, and resistant to oxidizing agent and reducing agent. Its thermostabillity is good, but photostability weak.

叶绿素铬钠盐能溶于水，在中性溶液中稳定，有一定的抗氧化还构原性，热稳定性好，光稳定性较差。

This study clearly showed that mosaic variation was caused by chlorophyll deficiency mutation of shoot tip histogen layer-Ⅱ;tissue and organs originated from the layer-Ⅱ couldn't synthetize chlorophyll,thus induced albino; the albino variation appeared yellow green mosaic because layer-Ⅱ was displaced by layer-Ⅲ partly.

研究表明，其变异原因是由于茎尖分生组织的L -Ⅱ组织原层发生失绿突变，致使其衍生的组织和器官不能合成叶绿素，从而形成白化现象；又由于L -Ⅱ与L -Ⅲ组织原层层间发生部分代换，致使白化突变呈黄绿镶嵌的花斑。

The results indicated that with the increasing of storage time, the leaves etiolated, contents of crude-fiber increased, while vitamin C, chlorogenic acid decreased, nitrate contents up to the maximum at the 3th day after storage , then decreased gradually. Stored at 2℃, the contents of chlorophyll, vitamin C, chlorogenic acid were higher, nitrate and crude-fiber contents were lower. The lower of membrane permeability and MDA content, the higher activity of SOD significantly delayed senescence process and prolonged storage life of Taraxacum mongolicum.

结果表明：采后蒲公英随着贮藏天数的增加，叶片逐渐黄化，粗纤维的含量升高，维生素C和绿原酸含量下降，硝酸盐含量先升高后降低；2℃下贮藏能够使采后蒲公英具有较高的叶绿素、维生素C、绿原酸，较低的硝酸盐和粗纤维含量，较低的细胞膜渗透率、MDA含量和较高的SOD活性，显著地延缓其衰老进程，延长贮藏寿命。

Spraying with chitosan of different concentration significantly increased the content of chlorophyll ,anthoxanthin ,chlorogentic acid, polyphenal ,soluble protein and total soluble sugar of Broccoli flowers. 40 mg L-l chitosan showed the most remarkable effet,compared to control, the content of chlorophyll ,anthoxanthin ,chlorogentic acid, total soluble sugar and soluble protein of treated Broccoli flowers increased by 64.4%,282.5%,35.6%,16.2% 22.7% respectively.PAL and PPO are key enzymes in synthesize of phenolics.No relation was found between phenolics synthesize and PAL activity in Broccoli flowers,but it showed positive relation between phenolics synthesize and PPO activity.

研究表明，本研究中，不同浓度几丁聚糖喷施对青花菜花球的叶绿素、类黄酮、绿原酸、多酚总量、可溶性蛋白及可溶性总糖的含浙江大学硕卜学位论文(2004)量有显著增加，其中以浓度为40mgL一'影响最为显著，花球中的叶绿素、类黄酮、绿原酸、可溶性总糖、可溶性蛋白分别较对照提高64.4%、282.5%、35.6%、 16.2%、22.7%，苯丙氨酸解氨酶、多酚氧化酶是酚类物质合成中关键酶，花球内酚类物质合成与苯丙氨酸解氨酶的活性没有一定的相关性，而与多酚氧化酶的活性呈正相关。

The results showed that Celtis julianae 'Aurea' belongs to chl-deficient type. The main cause of turning yellow was the blockage of chlorophyll biosynthesis which could be somewhere in the formation of Pchlide.

导致金叶珊瑚朴叶色金黄的原因是叶绿素的合成受阻，受阻部位可能在Mg插入卟啉环后合成原叶绿素酯时。

The content of intermediates such as protochlorophyll,Mg protoporphyrinand protoporphyrin IXwere reduced and δ aminolevulinc acid and porphohilinogenwere markedly accumulated in albino seedlings of W1,which proved that there was a blockage in the formation of uroporphyrinogen or coproporphyrinogen during Chl biosynthesis under lower temperature.

白化苗中Chl生物合成的中间产物原叶绿素、镁原卟啉、原卟啉IX含量减少，而δ氨基酮戊酸和胆色素原大量积累，证明突变体W1低温下Chl生物合成卟啉原形成部位受阻

The effects of dioxide germanium on soluble protein and chlorophyll contents, activities of protective enzymes of the protocorm of Dendrobium officinale are studied in this article.

研究了不同浓度的锗(GeO2)对组培铁皮石斛原球茎的鲜重、可溶性蛋自质、叶绿素含量以及保护酶系统(SOD， CAT， POD)活性的影响。

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。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
