The best estimator selection was also discussed. The results show that the correlation obtained by the equation established from FD is the best, and the lg (1/R) spectra can improve the retrieval of chlorophyll contents with remote sensing.

结果表明，叶绿素含量与反射率一阶微分光谱方程的相关性最强，而采用lg(1/R)的光谱形式能够提高遥感反演叶绿素含量的效果。

Taking the seedlings of Quercus glauca, a dominant evergreen broadleaf tree species in subtropical area, as test materials, this paper studied their photosynthesis, chlorophyll fluorescence, and chlorophyll content under effects of simulated acid rain with pH 25, 40, and 56. After 2-year acid rain stress, the net photosynthetic rate of Q.

选择亚热带常绿阔叶林优势树种青冈幼苗为研究对象，设置3个酸雨处理：pH 2.5、pH 4.0、pH 5.6，研究不同强度的模拟酸雨对青冈幼苗光合特性、叶绿素荧光参数和叶绿素含量的影响。

The changes of chlorophyll-a were detected in the zoology system of shellfish,fish and bulrush.

通过检测系统内叶绿素a含量的变化，以监测系统中各池贝类规格、数量与叶绿素a的变化关系。

3Photosynthetic efficiency was sensitive to the increase of plant density, which mainly caused by the decrease of content of chlorophyll, photosynthetic rate, and carboxylation efficiency which were positive correlation to yield per plant, and the decline of quanta efficiency was subordinate

3叶片光合效率对密度增加的反应较敏感，叶绿素含量、光合速率和羧化效率的降低是主要原因，它们与单株产量呈显著的正相关，叶绿素、光合速率和羧化效率之间也呈显著的正相关，量子效率的降低是次要的

The effect of aqueous infusion of pepper leaf on plant height, stem diameter, leaf number per plant, leaf area and the content of chlorophyll a, chlorophyll b and total chlorophyll, the activity of SOD and POD of pepper seedling all showed promotion with low concn. and inhibition with high concn. The conductivity and MDA content increased with the increment of aqueous infusion concn.

辣椒叶水浸液对辣椒幼苗的株高、茎粗、单株叶片数和叶面积、叶绿素a、叶绿素b和总叶绿素含量S、OD活性及POD活性的影响均表现为&低浓度促进、高浓度抑制&；而相对电导率和MDA含量则随着水浸液浓度的增加而增大。

Low chlorophyll b rice mutant and the wild type rice (Zhenhui 249) were used to study the effects of low chlorophyll b on themiostability of photosystem Ⅱ in mutant by measuring their changes in chlorophyⅡ fluorescence parameters and polyphasic chlorophyⅡ fluorescence transients under different temperature treatments.

通过测定不同温度处理后水稻低叶绿素b突变体及其野生型（镇恢249）叶绿素荧光参数和快速荧光诱导动力学曲线的变化，研究了低叶绿素b对突变体光系统Ⅱ热稳定性的影响。

When the plant N level was below 2%, the leaf starch accumulation kept stable, but the sugar content in leaf and starch content in lower layer leaf increased. When the plant N level was between 2. 0% and 2. 8%, the activity of SPS and leaf soluble sugar content were the greatest, which was favorable to the transportation of the accumulated matter from the leaf to the grain.

随植株氮水平提高，叶绿素总含量提高，但叶绿素b的提高速度快于叶绿素a；当植株叶片含氮率在2％以下时，随植株氮水平提高，水稻叶片淀粉积累不仅没有减少，相反叶片中的糖含量和下层叶的淀粉含量还有显著提高；当植株叶片含氮率在2.0％到2.8％的适宜水平时，叶片SPS酶活力和可溶性糖含量最高，有利于叶片中积累物质向籽粒转运。

Since chlorophyll plays such a vital role in photosynthesis, it has been studied extensively by plant physiologists in an effort to determine how it accomplishes its transformation of carbon dioxide and water into food.

由于叶绿素在光合作用中的重要地位，植物生理学家已经对叶绿素作了广泛的研究，旨在确定二氧化碳和水是怎样通过叶绿素合成有机物的。

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。
