Example Sentences:

	1.	Effect of nitrogen application on flag leaf senescence and yield of spring wheat 氮素施用方式对春小麦花后叶片衰老与产量的影响
	2.	Effect of n application rates on leaf senescence and its mechanism in maize was studied by methods of field experiment , plant analysis and electron microscopy examination 采用田间试验、植株分析及电镜检测方法研究了氮肥用量对玉米叶片衰老的影响及其机制。
	3.	The results showed that both inadequate and excessive nitrogen application accelerated the decreasing process of leaf area index ( lai ) and chlorophyll content at later growth stage , which led to earlier leaf senescence 结果表明，氮肥用量不足或过量均加速了生长后期叶面积系数及穗叶叶绿素含量的下降进程，使叶片提早衰老，但二者作用机制不同。
	4.	This paper reviewed the application of transgenic technique to tomatoes , introduced transgenic tomatoes with characters of delayed fruit and leaf senescence , disease and insect resistance , herbicide resistance , adversity resistan ce and good fruit quality 综述了转基因技术在培育延熟番茄、抗病虫番茄、抗除草剂番茄、抗逆番茄、改进番茄品质和延缓叶衰老番茄等方面的研究进展。
	5.	Large - scale hydrolysis of proteins occurs early in leaf senescence and is likely to dependent on the integrated action of groups of enzymes . the substrate for proteases in senescing leaves includes mainly enzymes and membrane proteins that function in photo synthesis 类囊体膜上结合的蛋白酶主要分为需能蛋白酶和不需能蛋白酶，参与类囊体膜蛋白和类囊体腔蛋白成熟时的加工以及外因导致蛋白质功能丧失时的降解。
	6.	When inadequate n was added , the chloroplast structure in mesophyll cell was damaged in ear leaf , the amount of carbohydrate decreased in mestome sheath , and excessive n - redistribution and n - transportation to grain from vegetative mass appeared , which resulted in earlier leaf senescence . excessive n application led to too high activity of nitrate reductase , excessive vigorous nitrogen metabolism and too much exhaustion of carbohydrate in ear leaf , which resulted in the lack of enough carbohydrate in the lower leaf , meanwhile , the expansive chloroplast grana lamellae in leaf mesophyll cell and starch grain without nuclear in mestome sheath cell was observed , which led to the decrease of chlorophyll content and photosythetic capacity in maize leaf , then the early senescence occured 氮肥用量不足导致穗叶叶肉细胞叶绿体结构性差，维管束鞘细胞碳水化合物累积减少,营养体氮素再分配率大而引起叶片早衰；而过量供氮则导致生长后期硝酸还原酶活性过高，氮素代谢过旺，消耗了大量碳水化合物，以致下位叶不能得到充足的碳水化合物供应而提早脱落，同时叶肉细胞叶绿体片层结构膨胀，呈“肉汁化”特征，维管束鞘细胞淀粉粒大量消耗，无核淀粉粒出现，从而叶片叶绿素含量下降，光合能力降低而出现早衰。
