叶绿素的

Magnesium is a component of the chlorophyll molecule, photosynthesis and serves as a cofactor in most enzymes.

镁是合成叶绿素和光合作用的必需元素，也是活化多种草坪酶的必要元素。

Turf color is a key index for apparent quality and the chlorophyll content is the main affecting facor.

草坪色泽是草坪外观质量重要的评价指标之一，叶绿素含量的高低反映了草坪色泽状况。

The result also indicated that plant height,stem thickness,leaf area index and relative content of chlorophyll in the leaves increased congruously,providing the nutritional basis for high yield and quality of forage maize production.

试验结果还看出，随钾肥用量的增加，饲用玉米株高、茎粗、叶面积指数和叶绿素相对含量均有提高，为饲用玉米的高产优质奠定了基础。

The result also indicated that plant height, stem thickness, leaf area index and relative content of chlorophyll in the leaves increased congruously, providing the nutritional basis for high yield and quality of forage maize production.

试验结果还看出，随钾肥用量的增加，饲用玉米株高、茎粗、叶面积指数和叶片中叶绿素相对含量均有提高，为饲用玉米的高产优质奠定了基础。

Strain 153 could improve the content of chlorophyll in leaves and enhance the deoxidize intensity of root so as to promoting growth.

放线菌153可通过定殖提高植株体内的叶绿素含量以及根系还原强度而促进番茄和茄子的生长。

The spectral reflectance of dichondra turf was studies by measuring the leaf relative water content, chlorophyll content and soil water content under different drought levels.

通过在不同灌水处理下马蹄金草坪干旱胁迫试验，对草坪反射光谱的变化及所对应的叶片相对含水量、叶绿素含量以及草坪外观变化进行测定。

All showed strong chlorophyll a fluorescence signals originating from the dinoflagellate endosymbionts.

均具有很强的叶绿素a荧光信号，这些信号来源于体内共生的甲藻。

After 48h of exposure, the color of leaf of Egeria najas became greenish badly and the leaf was conglutinated, and the chlorophyll content of leaf declined significantly when the Hg concentration were above 2.00mg/L.By the changes of chlorophyll content, the lethal concentration of Hg to Egeria najas was 0.10-2.00mg/L.

处理48h以后，Hg~(2 )浓度人于1.00mg/L实验组中的叶片褪绿严重而且叶片相互粘连，叶片叶绿素含量明显低于对照组，从中可以粗略看出Hg(2-)对细叶蜈蚣草的致死浓度为0.10-2.00mg/L。

The calculated IC times of chl-a in ethyl acetate, tetrahydrofuran and dimethyl formamide are 141, 147, and 241 fs, respectively.

计算得到的叶绿素a分子在乙酸乙酯、四氢呋喃和二甲基甲酰胺溶剂中的内转换时间分别是141、147和241 fs。

At the same time, etiolation rate of broccoli flower head with GA treatment is reduced significantly, and the decrease rate of chlorophyll and vitamin C content are slowed down.

同时发现，用赤霉素处理过的青花菜花球，其黄化率显著降低，叶绿素和维生素C含量的降低速度减缓。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
