类叶绿素

And value of cha b/ carotinoid and cha b/ flower pigment is increased, thecolor of the leaf is went to green.

而遮荫与干旱胁迫相反，遮荫使长李15号和紫叶李叶绿素a、叶绿素b、类胡萝卜素和总叶绿素含量增加，这是使植株更好的适应弱光的一种反应。

Of ch a, and value of cha b/ carotinoid and cha b/flower pigment are both reduced in ChangLi 15 and Purple leaf plum, the color of the leaf is moreobvious; Under shade environment, ch a/b is reduced.

Content of Chla,β-carotene and zeaxanthin of S. platensis grown in Se decreased, violaxathin, fucoxanthin, 19'-hexanoyloxyfucoxanthin and peridinin increased, Chla and Chlb of D. salina also decreased, but carotene increased, all pigments of D. zhanjiangensis increased except violaxanthin and 19'-hexanoyloxyfucoxanthin decreased. Effect of Ge on pigments of microalgaes were different in different algaes: Chla,β-carotene and zeaxanthin of S. platensis decreased, three other carotene increased, in D. salina, violaxanthin and lutein decreased, violaxathin, fucoxanthin and 19'-hexanoyloxyfucoxanthin increased, all pigments of D. zhanjiangensis increased except fucoxanthin and peridinin decreased; Chla,β-carotene and violaxanthin of Chlorella sp increased, but fucoxanthin and peridinin decreased.

暴露于硒中的钝顶螺旋藻（S.platensis）的叶绿素A、β-胡萝卜素和玉米黄素的含量都减少，岩藻黄素、19'-乙酰氧化岩藻黄素、多甲藻素和紫黄素的含量明显增加，盐生杜氏藻的叶绿素类也减少，但类胡萝卜素的含量则增加，湛江叉鞭金藻（D.zhanjiangensis）中除紫黄素和19'-乙酰氧化岩藻黄素有减少外，其它色素都增加；锗对四种微藻光合色素的影响也不尽相同，钝顶螺旋藻（S.platensis）的叶绿素A、β-胡萝卜素及玉米黄素含量减少，岩藻黄素、19'-乙酰氧化岩藻黄素和紫黄素的含量增加，盐生杜氏藻中除紫黄素和叶黄素有增加外，其它色素都减少，湛江又鞭金藻（D.zhanjiangensis）正相反，除岩藻黄素和多甲藻素有减少外，其它色素都增加，小球藻的叶绿素A、β-胡萝卜素和紫黄素增加较大，但岩藻黄素和多甲藻素则减少。

The results show that the ratios of chlorophyll to carotenoid, purpurin and red pigment for four maize genotypes decrease under low P dose. Those of "7922" and "Ye107" are 0.4~0.8 times those under high P dose, with much higher decrease than in "178" and "(superscript *)082".

结果表明，低磷条件下，玉米叶片叶绿素／类胡萝卜素、叶绿素／紫色素和叶绿素／红色素均减少，其中基因型"7922"和"掖107"的叶绿素／类胡萝卜素、叶绿素／紫色素和叶绿素／红色素减少幅度较大，为高磷条件下的0.4~0.8倍，且减少幅度高于"178"和"082"。

However, the ratios of chl a/ch b and carotenoids/chls were dropped due to drought, independently of sampling unit.

然而，不管是用单位叶面积的色素含量或是单位叶鲜重的色素含量计算而来的叶绿素a和叶绿素b的比率以及类胡萝卜素和总叶绿素的比率对土壤干旱引起的变化趋势是一致的，都表现为降低。

We selected two different scale parameters, leaf chlorophyll content and leaf area index, on the basis of the radiative transfer models PROSPECT and SAIL, respectively, for sensitivity study of a set of indices. We aimed to improve the linearity between the indices for chlorophyll content and leaf area index on the basis of combinations of different wave bands.

为了寻找合适的波段位置以改善植被指数与叶绿素浓度和叶面积指数的线性关系，去除饱和区域，进而提高这2个参数的实际估算精度，该文选取了叶绿素浓度和叶面积指数，以辐射传输模型PROSPECT和SAIL为基础，模拟了这2个参数变化对3类高光谱植被指数（归一化植被指数、优化的简单比值指数和优化的叶绿素吸收率指数）的影响。

However, a number of vegetation indices are not linearly related to biochemical components, so these indices may not be appropriate for other vegetative areas. We selected two different scale parameters, leaf chlorophyll content and leaf area index, on the basis of the radiative transfer models PROSPECT and SAIL, respectively, for sensitivity study of a set of indices.

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。

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。
