叶绿素

The effects of GA3 and IAA with different concentrations and combinations on the dynamic accumulation of holocellulose and chlorophyl content in Neosinocalamus affinis were studied.

以慈竹为材料，研究不同浓度和配比的GA3和IAA对综纤维和叶绿素含量动态积累的调控效应，为纸浆用竹的遗传改良研究提供理论依据。

Under drought stress, the chlorophyl content of strawberry present drop trend,but 5—20mmol/L Ca~(2 ) test stay it. So it has significance to keep strawberrysphotosynthesis ability and normal physiological function.

在干旱胁迫下，草莓叶绿素含量呈现下降趋势，而5—20mmol／L钙处理则延缓了这一趋势，这对维持干旱胁迫下草莓的光合能力和正常的生理功能意义重大。

The chloroplasts use the chlorophyl to convert sunlight into energy, just as plants do, eliminating the need to eat food to gain energy.

叶绿体用这些叶绿素把太阳光转化成能量。就像植物一样不用吃食物也可以获取能量。

In order to force the leaf color to change, we need to understand how leaves change color in the fall. In short, the temp drops and blockage in the veins is formed inside the leaves and it stops water from reaching every corner of the leaves. Then the chlorophyl disappears and they are replaced by those red and yellow pigments.

为了迫使叶子变色，我们就必需要了解它在秋天是如何变色的，简言之，温度下降阻碍叶片中的叶脉形成，因而停止了水份到达它的每一个角落，叶绿素跟著消失，而被红色和黄色的色素所取而代之。

The results showed that the leaf chlorophyl content increased as the phosphorus application increased from jointing to flowering stage under different water conditions, but decreased in the filling stage.

试验结果表明：不同水分条件下，随着施磷量的增加，小麦叶片叶绿素含量表现为拔节—扬花期迅速上升，灌浆期后迅速下降。

And the Content of chlorophyl, soluable sugar, root system vigor of T3,T4 treatment is the relative fine in all treatments, it has no distinct difference with CK.

而且T4，T3处理番茄幼苗的叶绿素含量、可溶性糖、根系活力在所有处理中表现较好，和CK无显著差异。

According to the changing of color as the qualitative index; the changing of weight and chlorophyl as the ration index.Make the optimum design for the fresh-keeping package of broccoli in normal condition.

本课题选用不同种类、不同厚度的薄膜包装西兰花，以颜色变化为定性指标、重量变化和叶绿素变化为定量指标，对常态状态下的西兰花保鲜包装进行了优化设计。

Using fresh chlorophyll distilled from fresh leaves of yulan as experimental material,this research analyses the change of the absorption spectra of chlorophyl under light of different wave length,different illuminating time,different temperature by means of using the WGS-9 chroma analysing instrument.

引言光谱分析在各个领域内有广泛的应用，对许多物质，光的吸收性是一个重要的本质特性，通过对物质的光谱分析可以得知它的元素组成成分[1]。在自然界中，叶绿素是广泛存在于植物的叶和茎中的绿色色素，它也有其特定的吸收光谱。

The results showed that exogenous salicylic acid at appropriate concentrations reduced cell relative permeability and lipid peroxidation, increased the content of chlorophyl and activities of antioxidative enzymes, thus reduced the injury caused by NaCl and enhanced the growth of strawberry.

结果表明：适当浓度的水杨酸能够降低盐胁迫下草莓叶片质膜相对透性和过氧化程度，提高叶绿素含量和抗氧化酶活性，从而缓解NaCl对草莓的伤害，改善草莓的生长状况。

ResultUnder low Nstress,the biomass,Nabsorption in plant,the activity of NR,the content of chlorophyl and soluble protein were decreased obviously and the activity of CAT and SOD were increased significantly.

结果低氮胁迫下，各糯玉米品种的生物量、植株吸氮量、硝酸还原酶活性、叶绿素和可溶性蛋白质含量和明显下降，而过氧化氢酶活性和过氧化物歧化酶活性明显提高。

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。
