In cylindrical organs, such as stems and roots, the term radial is often used instead of anticlinal
在圓柱狀的器官如莖、根中，通常用「放射狀的」這個詞來代替「垂周的」 。In mammals cvos include subfomical organ ( sfo ), organum vesolum lamina terminalis ( ovtt ), median eminence ( mr ), subcommissural organ ( sco ), recess of pineal gland ( rpg ), paraventricular organ ( pvo ), and area postrema ( ap ). also neurohypophysis, choroids plexes, and pineal gland are recognized as cvos by some researchers
但有人把神經垂體，松果體，脈絡叢等也列為室周器官。在魚類還有血管囊（位於神經垂體的緊後方，漏斗莖的後端。Stems pendulous, terete, many - noded
莖下垂，圓柱形，多節。At the surface of the pollen grains there are three types of aperturates, including three porates type, three colpates type and three porate - colpates type ; and four types of sculpture, namely, reticulate, striate, striate - reticulate and verrucate. the upper epidermal cells of the leaves of 12 species plants are detected with hpias - 1000 image analytic system through the treatment of binarization, and the experimental methods are proved stable. the results indicated that the waviness of the anticlinal walls ( sfc ) and the ratio of the feret ' s diameter ( slf ) of the epidermal cells of the middle lamina in the third node of leaves starting from the lowerest part of the stem have a relative constant range and could distinguish from each other. oieanolic acid, l, 5, 8 - trihydroxy - 3 - methoxyxanthone and swertiamarin are separately detected on the tlc, and the different chromatogram of various plants can be considered as characters of identification. the contents of oleanolic acid in 12 species of plants are determinated by hplc, but among the different plants and botanical organs their contents are different, and the highest content in flowers
本文對川鄂產獐牙菜屬藥用植物資源進行了野外調查、標本採集和鑒定，對12種乾燥藥材的性狀進行了描述，提供了可以鑒別的特徵。通過掃描電子顯微鏡觀察的12種本屬藥用植物的花粉粒均為單粒花粉，萌發孔有3孔型， 3溝型和3孔溝型三種類型；表面紋飾包括網狀紋，條狀?網狀紋，條狀紋和瘤狀紋四種類型。用hpias ? 1000高清晰度彩色病理圖文分析系統對葉片上表皮細胞作圖像分析，並進行方法學研究，結果表明，同種植物莖上第3節葉片中段主脈和第1側脈之間葉上表皮細胞垂周壁彎曲程度sfc值和細胞縱、橫向直徑的比值slf值，種間有顯著差異，每種都有相對恆定范圍值。( 3 ) firstly detectes the waviness of the anticlinal walls ( sfc ) and the ratio of the feret ' s diameter ( slc ) of the epidermal cells in the leaves of 11 species, and studies the methodology, then give out two conclusion : a. epidermal cells in the place between middle and first side vein of the lamina on the third kont starting from ground have the most stable microscopic characters
（ 3 ）首次採用計算機圖像分析「 hpias ? 1000高清晰度彩色病理圖文分析系統」測定了獐牙菜屬11種藥用植物葉上表皮細胞垂周壁彎曲程度（ sfc ）和細胞縱橫直徑比（ slf ） ，並進行了方法學研究，得到以下結論：莖上第3節葉片中段主脈與第一側脈之間上表皮細胞形態最穩定。For example, the basic angiosperm stem is vertical and elongated, but some cacti have swollen water - storing stems, while other xerophytic plants that have lost their leaves during the course of evolution have evolved flattened leaflike stems for photosynthesis, e. g. butcher ' s broom ( ruscus aculeatus )
例如被子植物的莖是垂直的，伸長的，但一些仙人掌具有膨大的能夠儲水的莖，另一些旱生植物在進化的過程中失去了葉子，但又發展為利用扁平葉狀的莖來進行光合作用（假葉樹） 。1. root : air roots are pending from the stem and branches
1 .根：氣根自莖枝高處下垂。Meanwhile, morphological characteristics of d. glomerata have significant relationships : those with upright and constrictive inflorescences have longer and narrower leaves, stronger stems, longer flag leaves, well - developed stamens and stronger seed reproductive capacity, whereas those with pendulous inflorescence have the opposite characteristics
2 ）鴨茅植物形態學特徵間存在明顯相關性，花序直立、緊縮的鴨茅，葉片窄長，莖稈粗壯，旗葉較長，雄性生殖器官發育良好，結種性能強；而花序下垂、開展的鴨茅則與之相反。A shallow - rooted, high - tillering variety has a very high root density around the plant base but the roots grow vertically as well as laterally
淺根、高分蘗品種在植物根莖周圍根密度很大，但根系同時向垂直和水平方向生長。分享友人
