ABSTRACT Fruit ripening is associated with a number of physiological and biochemical changes including degradation of chlorophyll, carotenoid biosynthesis, synthesis of flavor compounds, conversion of starch to sugars, cell wall solublisation and fruit softening.

果实的发育成熟涉及一系列复杂的生理生化变化，包括叶绿素的降解、类胡萝卜素的合成、淀粉向糖的转化、芳香性化合物的合成、细胞壁溶解和果实软化等。

The result indicated that the phenolic acid and its mixture could defer the remarkable time of wild oat seed germination, reduce seed germination rate, inhibit the physiological parameter and accumulated amount of dry matter to a certain extent, decrease the Root activity and chlorophyll content inordinately, and increase malondialdehyde level in seedling.

结果表明：酚酸类物质及其混合物可以显著延缓野燕麦种子发芽所需要的时间，降低最终的萌发率，对野燕麦幼苗的生理指标及干物质积累有一定的抑制作用，根系活力与叶绿素含量也有不同程度的下降，同时使幼苗体内丙二醛的含量显著增加。

Na2FlBr4Cl4 shows the maximum algaecidal activity, and the MLC value is 40μM with illumination and 90μM without illumination. From the research on the Na2FlBr4Cl4 against the growth of algae and the content of chlorophyll a, we obtains that xanthene derivatives have little effect on the growth of algae at low concentration and can restrain the growth of algae at middle and high concentration.

呫吨类化合物对铜绿微囊藻的测试结果显示：供试样品中对供试藻种活性最强的是Na2FlBr4Cl4，其MLC值为在光照条件下为40μM，在无光条件下为90μM；通过Na2FlBr4Cl4对铜绿微囊藻的生长量以及叶绿素a含量的影响的研究发现，在较低的浓度范围内，呫吨类化合物对铜绿微囊藻的生长没有太大影响，而在中高的浓度范围内，则能产生显著的抑制效应。

Effects of exogenous oxalate on photosynthesis, chlorophyll fluorescence and xanthophyll cycle in cucumber leaves under high temperature stress at 40℃ were studied.

在40℃高温胁迫条件下，研究了外源草酸对黄瓜叶片光合作用、叶绿素荧光参数和叶黄素循环的影响。

The colorant s of green plants consist of chlorophyll,xanthophyll and carotene.

本文应用微型化学实验仪器，对绿色植物中的色素进行提取和色谱分离

Chlorophyll contents and xanthophyll cycle pool calculated from reflectance were closely related with cucumber tolerance to salt stress, and reflectance characteristics could be used as index to evaluate cucumber cultivar tolerance to salt stress.

利用光谱反射指标得出的叶绿素含量、叶黄素循环库的大小与黄瓜的盐害程度及不同品种的耐盐程度有密切关系，反射光谱特性可以用来作为筛选黄瓜耐盐的生理指标。

Chlorophyll fluorescence analysis technique and HPLC system were used to investigate changes of thermal dissipation through xanthophyll cycle under high irradiance and xanthophyll cycle components in streptomycin treated maize leaves.

利用叶绿素荧光分析技术和高效液相色谱研究了链霉素(SM ，叶绿体基因编码蛋白的抑制剂)处理玉米叶片的叶黄素循环及依赖叶黄素循环的热耗散。

Do plants photosynthesize when chlorophyll transforms to xanthophyll?

叶绿素转变为叶黄素后是不是就不会行光合作用了？

Concentration of chlorophyll-a and zooplankton's carbon is farely high in this area.

浮游动物碳的垂向分布较为均匀，垂向浓度梯度较小。

Nutrients and feeding pressure of zooplankton affected the distribution of chlorophyll a and its size-fractionation.

营养盐分布和浮游动物的摄食压力影响了叶绿素a及其粒级结构的分布。
