叶片排列

For the BM-rice,the sclerenchyma of leaves was shrunken,vascular bundle of leaves was reduced,the strumae of outer epidermis of stem was sparse and the link of phloem of root was loosed and dispersed.

2通过扫描电镜观察，脆性突变水稻的组织结构发生了较大变化：叶片薄壁组织扩张，厚壁组织收缩，维管束数目减少；茎杆外表皮硅质瘤状结构分布稀疏；根中柱韧皮部组织排列稀疏，连接松散。

Leaves crowded near apex of the trunk, spirally arranged; stipes dark brown, with sharp spines; lamina large, oblong, tripinnate; pinnae 17-20 pairs, alternate, longest one to 60 cm long, the basal one reduced; rachis short-spiny; pinnules 18-20 pairs, sessile or nearly so, lanceolate, to 10 cm long and 2.5 cm wide, divided almost to the costa; segments more or less falcate, toothed.

叶螺旋状排列，聚生於茎端；叶柄棕色，具锐刺；叶片大，长矩圆形，三回羽状深裂；羽片17-20对，互生，最大的长达60厘米，基部一对缩短，羽轴有短刺；小羽片18-20对，无柄或近於无柄，披针形，长达10厘米，宽2.5厘米，深裂几达中脉；末回裂片多少镰状，有齿。

Leaves in spirals, usually odd-pinnate; leaflets opposite to subopposite; leaflet blades with margin entire or ± serrate.

叶螺旋状排列，通常奇数羽状复叶；小叶对生到近对生；小叶叶片边缘全缘或多少有锯齿。

Leaves alternate, spirally arranged, or subopposite at apex of branches; stipules small, caducous; petiole long, glandular at apex; leaf blade palmately compound, usually 3-foliolate; leaflets entire, petiolulate.

叶互生，螺旋状排列，或在枝的先端近对生的；托叶小，早落；叶柄长，在顶具腺的；叶片掌状复叶，通常具3小叶；小叶全缘，具小叶柄。

Leaves opposite, subopposite, or rarely spirally arranged; stipules small and early deciduous with conspicuous scars on petiole, sometimes subpersistent; leaf blade almost leathery.

常绿乔木；叶对生，近对生，或很少螺旋状排列；托叶在叶柄，有时近宿存上由于显眼的伤痕小和早脱落；叶片几乎革质。

Leaves usually alternate, sometimes subopposite; stipules early caducous; petiole long, without glands at apex nor along length; leaf blade pinnate-veined, lateral veins closely set, mostly 1(-2) cm apart, margin glandular-serrate or glandular-crenate, sometimes minutely so.

叶通常交替，有时近对生；托叶早落；叶柄长，没有腺体在先端也非沿着长度；叶片羽状脉，侧脉紧密排列，多数相隔（1-2厘米，边缘具腺锯齿或具腺圆齿，有时稍如此。

Leaves in spirals or rarely opposite, pinnate; leaflets alternate, subopposite, or alternate, petiolulate, not always an equal number on each side of rachis; leaflet blade base usually oblique, margin usually entire, very rarely serrulate.

叶螺旋状排列或很少对生，羽状；小叶互生，近对生，或互生，具小叶柄，轴两边小叶数量不总相等；小叶叶片基部通常偏斜，边缘通常全缘，极少有细锯齿。

And when they arise in pairs the arrangement is termed opposite, e.g. lilac (Syringa spp.).

当叶片成对的排列称为对生，如紫丁香。

Venation is the distribution of veins in a leaf.

脉序是叶片中各叶脉的排列分布状态。

Excessive O(superscript – subscript 2) could lead to the damage of cytomembrane, and as a result, the cytomembrane permeability was increase finally. On the other hand, the two kinds of weedicide could damage cell construct, expand cell interspaces, and shrink the guard cell.

灭狼毒"和"灭棘豆都可以使狼毒和棘豆叶片栅栏组织排列呈疏松变化趋势，细胞间隙增大，叶肉细胞结构破坏，形成大的空腔；保卫细胞萎缩，气孔下腔增大。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
