子叶

Seeds solitary, exalbuminous; testa membranous; cotyledons usually membranous, contortuplicate, rarely fleshy and planoconvex; radicle superior.

种子单生，无胚乳；种皮膜质；子叶通常膜质，卷折，很少肉质和平凸；胚根上位。

The preliminary bioassay showed that some title compounds exhibited certain fungicidal activities and cucumber cotyledon root-formation promoting activities.

初步的生物活性测试结果表明，部分化合物具有一定的杀菌活性和促进黄瓜子叶生根活性。

A dicotyledonous family of marsh plants of order Gentianales.

龙胆属沼泽植物中双子叶植物科。

The cotyledon explants excised from 5-day-old germfree seedlings were cultured on the MS medium containing 1.0 mg/L 6-BA in darkness for 3 days, and then further cultured under light condition for induction of adventitious buds.

结果显示：将从5 d龄甜瓜无菌苗上切取的子叶外植体接种在MS+6-BA1 mg/L的不定芽诱导培养基上，黑暗条件培养3 d，再转至光下继续培养，诱导出高效不定芽丛。

Nonethesless, this study indicated that European Gesneriaceae species is isocotylous because of no differential cell division, cell expansion, trichome distribution and lateral vein formation between both cotyledons.

未来针对上述基因进行表现及功能性研究相信能更加了解KNOX基因在子叶不等大现象扮演的角色。

Result The ordinary broad sense heritability rates of various traits were at extremely significant level, specially, that of bell weight, lint percentage, top stem thickness were more than 50% and that of the ginned cotton output per plant, bells per plant, plant height, stem thickness of cotyledon node were lower. The ordinary narrow sense heritability of the ginned cotton output per plant and bells per plant were 24% and 25% resp. and that of bell weight and lint percentage etc. were lower or zero.

结果］各性状的普通广义遗传率均达极显著水平，特别是铃重、衣分、顶部茎粗的普通广义遗传率达50%以上，单株皮棉产量、单株铃数、株高、子叶节茎粗普通广义遗传率较低，单株皮棉产量和单株铃数的普通狭义遗传力分别为24%和25%，铃重、衣分等性状的普通狭义遗传力较低或为0。

It is normally formed from the secondary xylem and thus found in plants that show secondary thickening, namely the conifers, Gnetum and dicotyledons.

木材丛次生木质部中形成，因此只有在进行次生加厚的植物中才具有，如：松类、 Gnetum 和双子叶植物。

可育的药壁发育正常同于单子叶型，直到2细胞花粉粒时期绒毡层才全部退化。

A unisexual reproductive structure of gymnospermous plants such as conifers and cycads, typically consisting of a central axis around which there are scaly, overlapping, spirally arranged sporophylls that develop pollen-bearing sacs or naked ovules or seeds.

球果单性裸子植物的生殖器，例如针叶树和铁树目植物，一般由覆满鳞片和褶皱的中心轴构成，长螺旋状排列的孢子叶，孢子叶最终成为花粉囊或裸露的孢子或种子

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
