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。
We use bezier curves to describe the shape of leaf midrib and embed the image of leaf into the space of local frames along the midrib curve 植物叶面的造型采用bezier参数曲线描述叶子中脉的形状，然后将叶子的纹理图象嵌入到叶脉曲线的局部标架中。
Profuse , small yellow - green chlorosis areas between dark green veins of older or mid - stem leaves , followed by numerous small brown necrotic spots 缺锰番茄叶片：老叶或茎中部叶片的深绿色叶脉上有大量的失绿黄化小区，随后转变成大量褐色坏死小斑点。
Above the skeleton of a fallen leaf stalks the dark shape of a spider out hunting for springtail or mite or whatever tiny invertebrate strays its way 在一片落叶的叶脉上，潜伏着一只蜘蛛的黑影，它正准备猎捕弹尾虫、螨虫，或是任何一种迷路的微小的无脊椎动物。
In comparison with ck , obvious morphological variation were observed in the transgenic tobaccos . their leaves became greener and thicker , chief veins turned bolder and thicker than those of ck 与对照相比转基因烟草在形态上发生了明显的改变：叶片颜色变深绿；叶片增厚；主叶脉变粗壮等。
As for the leaves , we use bezier curves to describe shape of leaf midrib . the texture image of leaf is embedded into the space of local frames along the midrib curve 对于叶片的生成,本文采用bezier参数曲线描述叶子中脉的形状,把树叶或草叶构成的星形结构纹理图象嵌入到叶脉参数曲线的局部标架中来实现。
Older leaves ( except sometimes the first leaf and also cotyledons ) show bright yellow or orange blotchy interveinal chlorosis , leaf margins are inrolled . tips of leaflets scorch and leaves wither 番茄缺钼叶片：老叶（除此之外第一片叶和子叶有时也会）出现嫩黄色或橙色斑点的叶脉脉间失绿，叶缘不卷曲，叶尖端枯萎，叶片脱落。
Camellia granthamiana is a type of tree , its leave alternate , elliptical , coriaceous , margin with small blunt teeth . upper leaf surface is shining darkgreen , lower is paler and with veins protruding and clearly marked 大苞山茶是一种常绿乔木，叶互生，椭圆形，具革质，叶面光亮深绿色，叶背色淡，有清晰叶脉琥凸出，而叶缘具细小的纯。
The bell played to ring , have long time no see of bell , sink into the leaf vein from the treetop of december , is thorough toward the root of the winter , my soul greets this intimate warm current , my heart , deeply bless you 钟声奏响了，久违的钟声，从十二月的树梢沉进叶脉，向冬天的根部深入，我的灵魂迎接这至爱的暖流，我的心，深深祝福你！
