叶片排列

Compass plant A plant with its leaf edges permanently aligned due north and south.

指向植物：一类叶片的边缘始终南北排列的植物。

Leaves decussate, subopposite, or spirally arranged; blade scalelike, subulate, or linear to elliptic, stomatal lines abaxial or present on all surfaces.

叶交互对生，近对生，或者螺旋状排列；叶片鳞片状，钻形，或者线形至椭圆形，背面有气孔线或两面均有气孔线。

The resulsts indicated that:there was a great difference in the pollen shape of male and female Vitis, the pattern of SOD isozyme were the same in male and female dioecism Vitis; some of the results of RAPD were polymorphic between the male and female.

结果表明：葡萄雌雄株的花粉形态存在着较大的差异；在本实验条件下葡萄雌雄株叶片SOD同工酶谱带一致；一些引物的RAPD产物间存在着多态性，在葡萄雌雄株的基因组DNA序列中存在着碱基排列顺序的差异。

Kalanchoe; sunken or protected stomata e.g. marram grass; folding, rolling or repositioning of leaves to reduce sunlight absorption, e.g. marram grass; a dense covering of white reflective spines, e.g. cacti; and the development of a dense hairy leaf covering, e.g. Espeletia.

通过减少水分流失而生存的旱生植物的生存策略包括：落叶，如：墨西哥刺木；分泌蜡质覆盖叶片使气孔器被封闭或堵塞，如：滨草；折叠、卷曲或重新排列叶序而减少对日光的吸收，如：滨草；喜砂草盖白色的可以反射太阳光的刺，如：仙人掌；还可以发展出密毛状叶片铺满全身各处，如： Espeletia 。

The results are as follows:(1) The morphological investigation indicated that the nectaries werelacked on the main nervation, calyx and bract of cotton line 97014 comparedwith TM-1. Alveolate hollow was absent at main nervation of the mature leaf.Results of cytological analysis showed that 97014 lacked nectariferous structure.Where nectary inserted were parenchyma cells, cupped structure and brownnectariferous substance on the lower epidermis were not found.

主要研究结果如下：(1)以棉花无蜜腺品种97014与有蜜腺棉花遗传标准系TM-1为材料，进行形态学比较研究，结果表明棉花无蜜腺品种97014叶片中脉、花萼和苞叶上都缺少蜜腺，成熟叶片叶脉、花萼和苞叶上均无蜂窝状凹陷；组织与细胞切片观察发现，97014缺少蜜腺组织结构，在蜜腺着生处为排列整齐的薄壁细胞，且在下表皮看不到凹陷的组织结构和褐色的蜜腺分泌物。

Results The stomata,rang of palisade tissue in leaves and distribution of xylem fiber in stem had certain identity.

结果叶片气孔轴式、栅栏组织的排列、细胞内容物、茎中木纤维的分布具有一定的鉴别特征。

Leaves in spirals, odd-pinnate or occasionally a single leaflet; leaflets opposite; petiolule bases inflated and jointlike; leaflet blades abaxially pale, margin entire.

叶螺旋状排列，奇数羽状复叶或偶有单个小叶(有时Walsura pinnata有)；小叶对生；小叶柄基部膨大，关节状；小叶叶片背面浅色，边缘全缘。

Comprehensive comparing the thickness of cuticle, the quantity of sclerenchyma and the density of vein-bundles of the leaves of 7 cultivars, a comprehensive index of rub-resistant character of leaf was gained as one of tramp- resistant character indexes.

综合比较7个品种叶片的角质层厚度、机械组织含量、维管束排列密度，得出叶片耐磨性综合指数，可作为耐践踏性的指标之一。

Leaves in spirals, odd-pinnate, trifoliolate, or simple, when compound lateral leaflets opposite; leaf blade or leaflet blades with margin entire or sparsely crenate.

叶螺旋状排列，奇数羽状复叶，具三小叶，或单叶，如为复叶其侧生小叶对生；叶片或小叶叶片边缘全缘或疏生圆齿。

Main conclusions are as follows:(1) changes of leaf morphological and anatomical structures with tree height:25 researched tree species exhibited xeromorphic structures at tree top,that is,toward tree top,leaves were with 1 increased cuticle thickness;2 developed palisade tissue and even double-palisade structure;3 densely arranged tissue cells;4 smaller cells;5 thicker epidermis,smaller and denser stomata;6 smaller and thicker leaf,great LMA value.

本文主要得出以下结论：(1)叶片结构随树高的变化：研究的25种树种表现为越往树顶处：1角质层越厚；2栅栏组织越发达，全栅特征越明显；3叶组织细胞排列越紧密；4叶肉细胞越小；5表皮层越厚，气孔越小而密、单叶的气孔总面积越小；6叶片越小而厚，LMA越大。

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。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
