您要查找的是不是：
- Foliage dull dark green at tips or margins of leaflets and withering of older leaves. 马铃薯缺磷:植株小叶的尖端和边缘暗绿,老叶干枯;
- Bright yellow interveinal chlorosis of older leaves followed by red mottling, and often purple tinting in many brassicas. 缺镁的椰菜叶片:老叶脉间黄化;随后出现红色斑点;在许多芸苔中常转变成紫色.
- Born toxicity led to early abscission of the older leaves, reducing total photosynthesis leaf area, but did not influence SLA or LWR. 硼中毒导致成熟叶片过早脱落，使光合面积变小；过量供硼对比叶面积和叶重比没有影响。
- Blotchy irregular interveinal fading and orange-yellow chlorosis of older leaves, margins culed and sometimes scorched;younger leaves remaining green. 甜菜锰中毒：带有不规则斑点的叶脉间褪色，老叶变为桔黄色，边缘卷曲，有时枯萎，幼叶保持绿色。
- It also energizes Phosphorus.Deficiency will exhibit a yellowing and interveinal chlorosis beginning in the older leaves. 生态镁不增加土壤中阳离子，可直接被草坪草叶片吸收，能深入土壤草坪根部，吸收效率高。
- Boron toxicity reduced total leaf area by way of abscission of the old leaves, but did not influence SLA or LWR. 硼中毒导致成熟叶片脱落;从而影响叶面积;但对特定叶面积(SLA)和叶片重量比(LWR)没有影响.
- The DPM per unit of young leaf PPO was enhanced 71 percent as compared with that of old leaf. 嫩叶PPO的3H－亮氨酸DPM/活力单位比老叶的高出71%25。
- A plant that retains its old leaves right through the summer is being overwatered, it may not flower and is at risk of rotting and dying. ...... 大意是：如果夏天植物的旧叶还在，是说明水浇多了，后果可能会是不开花，并有腐烂和死亡的风险。
- The leaves can be added to salads, but it is best to marinate the older leaves in vinaigrette for 30 minutes first, as they are much less tender than the young leaves. 叶子能被增加来做为沙拉，但它最好先把较老的叶子用卤汁泡在香醋里30分钟，因为他们比年轻叶子较不嫩。
- Growth dwarfed, leaves small on long slender petioles; foliage pale green, older leaves becoming bright yellow, red or orange tinted, sometimes purple and falling prematurely. 花椰菜缺氮：植株矮小，叶小，叶柄细长，叶片淡绿，老叶黄化或显橙色或红色，有时出现紫色并过早死亡
- The new body actually draws out the water stored in the old leaves to continue growth, so do not remove the shriveled leaves. 不过在下次浇水之前必须确保突然土壤已经干燥，因为长期湿润的突然可能会导致生石花腐烂。
- Older leaves pale with faint diffuse, interveinal chlorosis mainly in marginal areas and along main veins, sometimes absent in spite of development of “marsh spot”. 缺锰的豌豆：老叶叶色变淡并轻微扩散，脉间从叶缘开始失绿，向主脉扩展，有时由于湿斑病的发展而不显现缺素症。
- Younger leaves faded green and lusterless; older leaves marginal scorch, interveinal blotchy chlorosis, necrotic patches bleaching and withering; characteristic of some soil acidity conditions. 甜菜锰和铝合并中毒：幼叶褪绿失去光泽，老叶边缘枯黄，脉间有坏死褐色斑点，接着白化，枯萎。这是酸性土壤特有的。
- Nitrogen deficiency causes stunting of growth and chlorosis of older leaves, as chlorophyll pigments are broken down so their components can be reused in the young growing parts of the plants. 氮的缺乏可以导致生长的迟缓和老叶片的缺绿症，因为分解的叶绿素被新生的叶片重新利用了。
- Type genus of Cycadaceae: genus of widely distributed Old World evergreen tropical trees having pinnate leaves and columnar stems covered with persistent bases of old leaves. 凤尾松科的模式属；广泛分布在旧大陆的一种热带树，具有羽状的叶子和被老叶子持久覆盖的筒形的树干。
- He is a great guy, a chip off the old block. 他是一位好人，就像他父亲一样。
- That old man is a fount of wisdom. 那个老人有无穷的智慧。
- The old farm has been split up into house lots. 这古老的农场已被划分为一块块的宅地。
- The old man stared the uninvited guest up and down. 老人把不速之客上下打量了一番。
- Compared with old leaf, SOD, POD and PPO in the infected leaf of rose were increased 49.83%, 280% and 700% resp ectively. 与老叶相比，感病后病叶的SOD、POD、PPO分别上升49.;83%25，280
