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 experiment that aPplication of Put shows that Put can inhibit chlorophyll discomposing and lower POD activity; Lower concentration (about 5mmol/L) can decrease respiration rate; ethylene's synthesis result in prolonging the storage time; Higher concentration (about l0,20mmol/L) Put can activate the respiration in some degree and disadvantage to storage.

外源腐胺处理香蕉果实的实验表明，腐胺可以减缓叶绿素的降解，另外，低浓度的（5mmol/L左右）腐胺可以较好的抑制乙烯的生成和呼吸作用，延缓果实衰老，而高浓度（10、20mmol/L）则在一定程度上刺激了呼吸作用，对贮藏不利。

Sulfur can promote the formation of chlorophyll; sulfur involved in the process of nitrogen fixation, to increase the utilization rate of fertilizer; in cruciferous rape, peanuts propylene mustard oil, Liliaceae onions and garlic contained in Suanyou fat, such as sulfur compounds in human nutrition and medicine There are special effects to enhance the quality of these crops.

硫能促进叶绿素的形成；硫参与固氮过程，提高肥料利用率；十字花科中油菜、花生的丙烯芥子油，百合科葱、蒜中所含的蒜油等硫脂化合物在人体营养和医药方面有特殊的功效，提高这类作物的品质。

The result indicated, along with density (5mg/L, 10 mg/L, 15 mg/L, 20 mg/L, 50 mg/L, 80 mg/L) the increase, the chlorophyll content, after the cell membrane lipin peroxidation presents the tendency which rises first drops.

在低浓度的胁迫下，叶绿素的含量和细胞膜脂质过氧化水平均上升，这是植物进行自我保护的表现，也是对外界的一种适应；当浓度达到某一特定值后，随着浓度的增加，均下降，说明植物受到重金属不可逆的损害。

Concentrations of water soluble phenolic substances in the leaves of male and female trees of Acer negundo L.were successively determined within an entire growing season by method of iron tartrate colorimetric analysis.

采用酒石酸铁比色法对复叶槭雌、雄株叶片中水溶性酚类物质的含量进行了一个生长周期的跟踪测定，对不同性别、不同年龄、不同光照条件下的复叶槭植株叶片中水溶性酚类物质的含量做了比较分析，同时研究了叶片中叶绿素的含量与水溶性酚类物质含量之间的关系。

The biomass photosynthesis activity of Ruppia maritima and Potamogeton pectinatus and the proline,malondialdehyde,catalase,and chlorophyll contents in their leaf-tissues in response to salinity were studied by investigating the plants cultured with reclaimed wastewater of different salinities.

通过在不同盐度再生水中培养川蔓藻和蓖齿眼子菜，研究了它们的生物量、光合强度及其组织中的脯氨酸、丙二醛、过氧化氢酶和叶绿素的含量变化对再生水中盐度的响应。

The results showed that the decreasing of the hardness was inhibited, the 1st fracture drop off was maintained, and those such as the production of the ethylene , the degrading of the chlorophyll, the decreasing of the titratable acid were inhibited, as well as the changing of the enzyme activities. And 1-MCP can keep a better condition of the inner structure of the tomato.

结果表明，1-MCP的处理减缓了硬度的下降，在一定程度上可以保持果实的脆度，抑制乙烯生成，阻止叶绿素的降解，降低可滴定酸的减少，对酶活变化起到了一定的抑制作用，同时较好地保持了番茄果肉组织结构的完整性。

Determination of photosynthetic pigments used 80% of acetone extraction method directly and the photosynthetic characteristics of using Li-6400 portable photosynthesis detector. Results showed that Returning the right amount maize straw stem into field was able to significantly restraint this year winter wheat flag leaf Chla degradation, to raise the flag leaf Chla/Chlb in the watery metaphase and late stage, to effectively restraint the photosynthesis rate decrease in the watery stage, to increase the pertinence of photosynthesis rate and pigment compared to others. However returning more maize straw stem into field was able to accelerate the retrogradation of chlorophyll and photosynthesis rate decrease then the yield declined.

结果表明：适量的玉米秸秆还田(9 000 kg/hm^2)可显著抑制接茬冬小麦灌浆中后期旗叶Chla降解，提高小麦灌浆中后期旗叶Chla/Chlb的比值，有效抑制灌浆期旗叶光合速率的下降，与其他处理相比，其光合速率与叶绿素的相关性得到加强；过量的秸秆还田(15 000 kg/hm^2)，加速了光合色素的降解，使得光合速率下降，产量降低；在各处理中，处理Ⅱ(9 000 kg/hm^2)产量最高。

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&。
