leaf layer

Studied on leaf layer structure and light distribution in High-yield Corn Population and their effects on Yield

玉米高产群体叶层结构和光分布与产量关系的研究

The results showed that there were significant differences in stomata density, epidermis length, epidermis width, epidermis thickness, cuticle thickness, leaf thickness, layer of the mesophyll thickness and the diameter of the vascular bundle.

结果表明：这些假俭草在气孔密度、表皮细胞长度、表皮细胞宽度与厚度、角质层厚度、叶片厚度、叶肉层厚度、维管束直径的大小等方面有显著的差异。

The information source nodes take the inherent connection among information processing nodes as the leaf nodes of layer structure and connect them.

信息源节点则按其与信息处理节点的固有连接作为层次结构的叶子节点进行连接。

This framework is of layered and distributed structure, including a central control node layer, a convergent node layer and a leaf node layer.

该框架是分层分布式结构，由中央控制节点层、汇聚节点层和叶节点层构成。

The earth surface of the region across it is mostly thicker humus soil or leaf falling covering layer, and has good heat reserving property, it is mostly weathering shingle, soil-aggregate mixture, and clay-gravel 0.5m-4.0m under it, and weathering rock.

所经地区的地表多为较厚的腐殖土或落叶覆盖层，其保温性良好，下层0.5&4.0米多为风化沙砾、碎石土和砾石土，，4.0米以下为风化岩石。

The experiment indicated that, in the blast environment, the leaf layer relative humidity was reduced greatly, and that the air quality, the stoma conduct of leaf, dehydration rate, respiratory rate, products of soaking row tea, free amino acids increased.

结果表明，恒温恒风调控方式能有效降低叶层空气的相对湿度，改善空气质量，增大青叶的气孔导度、失水速率及呼吸速率，提高毛茶的水浸出物和游离氨基酸含量，毛茶品质较优。

Arthropods communities were extremely significant difference among the tree layer, shrub layer, herbaceous layer and leaf litter layer, the individual number, species number, species diversity and evenness index of Arthropods were the maximum in herbaceous layer.

节肢动物群落在林冠层、灌木层、草间层和枯落物层4个垂直层次之间有极显著差异，草间层具有最高的物种数、个体数、多样性指数和均匀度指数。

The density of stoma in the down-epidermis was bigger than the up-epidermis, the two sides of the leaf had corneous layer.

叶为异面叶，表皮毛为多细胞型，下表皮气孔密度多于上表皮，上下表皮均有角质层。

The main indexes which affected leaf yields were root diameters, long branch number, long branch length, the ratio of seedling height to crown diameter, and the ratios of crown diameter to leaf layer depth.

对当年叶产量影响最大的指标分别为地径、长枝数、长枝长、高幅比及冠长比。

Multiple linear regression analyses showed that the coverage and height ( or depth) of canopy layer, herbaceous layer and leaf litter layer were the most important factors in determining the family richness, abundance, diversity;

多元回归分析表明，林冠层、草本层及枯落物的高（厚）度和覆盖率是决定科丰富度、个体数量、多样性和均匀度的决定因素。

Results showed that while there was one axillary bud on every leaf layer in mono corm taro, there were more than three in multi corm taro with one buds bigger than others.

结果表明，魁芋每一叶轮上腋芽数目为1；

The detection of virus in plant leaves with the technique of embedding virus-infected leaf tissue in layer of gel containing antiserum

血清凝胶组织封埋法检测植物叶片内的病毒

The SOD activity of D.involucrata leaves as affected by both biological and non-biological factors, and varied with age class, leaf position and leaf layer.

即珙桐叶SOD活性受生物和非生物因子共同影响，且不同年龄级、叶位、层次均存在差异。

The results showed that, crimpy leaf character decreased drooping degree and projection area of leaf significantly, thus increased percentage of leaf area in upper leaf layer, and optimized canopy light transmission;

结果表明，卷叶性状可显著降低叶片的披垂程度，减少叶片投影面积，增加群体上层叶面积的比例，改善群体内部透光状况。
