查询词典 lanceolate leaf

Culm internodes terete; leaf blades 2–4 per ultimate twig; leaf sheath oral setae present

Culm节间圆柱状；每末级的小枝叶片2-4；叶鞘口头的刚毛宿存 63

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有&盾状心皮&的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出&囊状心皮&的特点。

A very variable species: specimens occur with spinescent or obtuse leaf apices and with or without white stomatal bands on the adaxial leaf surface.

一非常易变的种：标本发生具具刺或钝叶尖并且有或没有白色气孔带在叶正面上。

The content of flavanone and lactone in leaf and the leaf output were studied by randomizing block arrangement of 31 gingko female varieties and 4 staminiferous plant type single clone.

采用31个银杏雌性品种和4个雄株类型的单株无性系，随机区组排列，对叶产量性状及其与叶产量的相关性，叶黄酮、内酯含量进行了研究。

Basal leaf blade ovate-cordate; cauline leaf borne near base of stem; staminode lobes oblong.

基生叶卵状心形；忍受的茎生叶干的近基部；退化雄蕊耳垂长方形。

Potato transpiration rate, stomatic diffusive resistance, leaf chamber temperature and leaf temperature were all affected by drip irrigation frequencies to some extent.

马铃薯的蒸腾速率、气孔阻力、叶室温度、叶温均受到了滴灌灌水频率的一定影响。

Secondary leaf veins usually unbranched; leaf blade elliptic, base cuneate to subobtuse

叶次脉通常不分枝；叶片椭圆形，对微钝的基部楔形 8 S。 elliptifolium 椭圆钻地风

The results showed that leaf epidermal characters of the genus revealed a remarkable consistency: the leaf epidermal cells were usually polygonal and subpolygonal bearing with straight or arched anticlinal walls; and the stomatal apparatus was mainly anisocytic type and presented in abaxial epidermis of all studied species.

结果表明秋海棠属植物叶表皮形态在属内组间具有较大的相似性，表皮细胞为多边形或近多边形，垂周壁平直或弓形，大多数种类表皮细胞内具有晶体，气孔器仅分布于下表皮，且以不等型为主。

This study evaluated the physiological effects and biochemical characteristics of functional axial leaf and different position sympodial leaf as affected by applying different levels of nitrogen fertilizer(0 kg/ha Low N;189.50 kg/ha Middle N;395.0kg/ha High N) using Bt-transgenic hybrid cotton variety 33B.

通过3个氮素水平(低氮0 kg/hm2、中氮189.50 kg/hm2、高氮395.0 kg/hm2)处理，研究棉花主茎功能叶和不同部位果枝叶衰老过程中的生理生化变化特征。

The average RMSE between the simulated and observed values for the dry matter partitioning ratio index of unit organs on main stem and sympodial stem with 33B cultivars was 0.028、0.017、0.013、0.035、0.021、0.009、0.011、0.014 for stem,leaf,petiole,branch on main stem,and branch,leaf,petiole and cotton bud and boll on fruit branch,respectively.

结果表明，模型对主茎、主叶、主柄、主茎分枝、果叶、果柄、果枝茎、蕾铃等单位器官在不同GDD时刻的比例指数动态过程均有较好的预测性，模拟值和观测值之间的RMSE平均值分别为0.028、0.017、0.013、0.035、0.021、0.009、0.011、0.014。
