The golden earth dried flowers craft processing factory is established October, 2007, mainly manages the product is the lignin handicraft, the example: The leaf vein flower/dragon willow tree/three fork willow tree/three fork wooden/purple willows and so on diverse natural green product, the factory uses the division of labor and cooperation flow, pure artificial careful processing guarantee product quality.

金大地干花工艺加工厂成立于2007年10月，主要经营产品为木质工艺品和绿化苗木，例：叶脉花/龙柳/三叉柳/三叉木/曲柳等多样天然绿色产品，工厂采用分工合作流程，纯人工细致加工保证产品的质量。

Expression of CAD1-A could be induced by fungal elicitor.

以前的实验结果表明CAD1-A启动子能驱动GUS基因在转基因烟草的叶脉和根部表达。

Papaya leaf curl China virus occurred widely and caused severe disease in papaya in the suburb of Nanning,Guangxi Province.In 2002—2004,the incidence rate reached 47.23%—100% in severely infected papaya fields,and the symptoms in infected papaya included stunt,downward leaf curling,dark green vein and enation,and petiole twist.

番木瓜曲叶病毒病在广西南宁市郊区发生严重并造成很大经济损失，经2002-2004年调查，重病果园发病率高达47.23%-100%，染病番木瓜矮缩，叶片向下卷曲，叶背部叶脉增生，叶柄扭曲，早期染病植株无法开花结果。

Mericarps 9-15; epicalyx lobes not leaflike, 3-6 × 1-2 mm

A Mediterranean plant (Eruca vesicaria subsp. sativa) having flowers with purple-veined, yellowish-white petals and leaves that are sometimes used in salads. Also called arugula , rocket salad , roquette

芝麻菜，紫花南芥：一种生长于地中海的植物（芝麻菜属芝麻菜亚种绵果芝麻菜），它的花有紫色的叶脉和黄白色的花萼，叶子有时用在沙拉里也作 arugula ， rocket salad ， roquette

The abnormal forms and the variations of other characters were observed or examined, such as plant short, leaf variations(contain leaf etiolation, leaf notch, leaf roll, and main leaf vein partial nondisjunction, etc.), growing period, cold hardiness, scourge-like caudex differentiation, corm weight increase, and so on.

这些可观察或可检测的变异有形态异常，主要表现为植株矮小及叶片畸形（包括叶片黄化、缺刻、叶卷曲及主叶脉粘连不分离等）；还有其它的性状变化，如生长期、根系、鞭状茎分化、耐寒性，球茎增重和产量等。

In addition, the edges, veins, skeleton and fissility of plant leaf are also primary features for plant morphology. So we also studied the method of the automatic extraction of these structural features from leaf images, which is a necessary step to design an automatic plant species system.

另外，叶片的叶缘、叶脉、骨架、裂深等叶片结构特征是植物数值分类学的主要分类性状，也是植物形态学分类的依据，通过数字图像处理技术实现这些性状的自动提取，是计算机辅助植物物种识别的重要内容和必然环节，所以对这些叶片结构特征的自动提取方法也进行了研究。

They stretch out, the matte green of their leaves conveying what it would be like to touch them, to run your finger down the blade and feel the rough resistance of these durable plants' skin: the gama grass, rough hair grass and broom beard grass.

一串红的叶子是心形的，叶子两边有锯齿，叶脉也非常清晰。

The size and localization of oil cells in the leaves, combined with the thickness of leaves, the number of layer of palisade tissue, the ratio of the thickness of palisade tissue to that of spongy tissue, the hypoderm, and the type of hairs, may be used as the identification characteristics of the generas, and even species.

木兰科植物油细胞的分布及其大小与叶厚、栅栏组织层数、栅栏组织与海绵组织厚度间的比值以及下皮层的有无、表皮毛的类型、叶脉的结构等特征相结合，可作为该科中属、甚至种的鉴别特征。
