When cultivated in medium with a certain level of antibiotic, the percentage of callus inducing of cotyledon burl is always the same, while the percentage of callus inducing of leafsteak is different.

在一定浓度抗生素的培养基中，子叶节的愈伤组织出愈率均为100%，而叶柄的出愈率在不同的浓度下会有明显的不同。

For instance, the percentage of cotyledon embryos is 92. 1% after 5weeks of culture in Nitsch medium.

经过筛处理的细胞团，在Nitsch培养基中培养5周后子叶型胚的比率可以高达92.1%，而且再生苗的畸形苗的百分率下降至38.5%。

Other courses like dendrology for gardening, taxonomy of seed plants, plant classification or plant systematics may be similar or overlap in some degrees. However, dendrology focuses on woody plants, especially on trees from gymnosperms and dicotylerdons of angiosperms. Dendrology for gardening is more suitable for students from specialties relating to gardening.

类似并可以在一定程度上起替代的课程为园林树木学、种子植物分类学、植物分类学或植物系统学，但树木学主要侧重于木本植物的分类，而且主要集中在裸子植物和被子植物的双子叶植物纲上中；园林树木学则主要适用于园林相关专业的学生。

At present, most genes were isolated by screening the cDNA or DNA library with theprobes homologous to sequences of dicot plants, and their functions were identified by themorphology of floral organs in transgenic plant.

目前研究手段主要是利用双子叶植物的同源序列来筛选水稻的cDNA文库，获取相关基因，然后根据转基因植物花器官的表型来验证该基因的功能。

The cotyledons and hypocotyls from the NW-174 had the highest transformation efficiency.

对NW-174新型栽培种实生苗的子叶、下胚轴进行的侵染实验表明，这两种组织的转化率较高。

Herbs aquatic; at least female flowers lacking petals or inconspicuous; fruit splitting at maturity into (2-)4 1-seeded mericarps; leaves whorled, at least the lower ones pinnately divided.

肾形，卵形的叶，或正三角形；四棱形的果圆柱状或，裂爿先端容易与分离在开裂的假隔膜；子叶现任。 2 Myriophyllum 狐尾藻属

The frequency and amplitude of wake force were deduced theoretically, while the influence of stator sector distribution and stator vane quantity on the wake force of vane was also discussed. Transient analysis was conducted for the forcing response of rotor blades under the same stator sector distribution and different quantities of stator vane, so an optimum asymmetry stator mistuned design was developed.

对不对称静子叶片非谐情况下激振力频率幅值进行推导，讨论了静子扇区分布和静叶数目选取对尾流激振力的影响，并对相同扇区分布不同静叶数目情况下转子叶片的强迫响应进行瞬态分析，给出不对称静子非谐设计的最优方案。

The functionof seed specific promoter Napin cloned by our lab was confirmed in Arabidopsis, it can drivegene expression in the seed derived cotyledons and hypocotyl in seedling stage, and in theskins of siliques in the mature stage.

在拟南芥中检验了本实验室克隆的油菜种子特异表达的启动子 Napin，表明 Napin 驱动基因在幼苗的子叶和下胚轴表达，在成熟期驱动基因在角果皮中表达。

RT-PCR analysis revealed higher expression levels of GmRLCK in soybean cotyledons,roots,flowers and young pods;whereas lower expression levels were detected in radicles,stems and mature leaves at vegetative stage.

RT-PCR的结果表明，GmRLCK在大豆子叶、根、花以及豆荚中都有较高的表达，而在胚根、茎和成熟叶片中的表达相对较弱。

Seeds pyriform or rarely irregular in shape; seed coat membranous or thin and brittle; endosperm copious or ± scant, fleshy; embryo relatively large, bent double or rarely broadly horseshoe-shaped; cotyledons plano-convex and linear or ± flattened and elliptic-oblong; hypocotyl superior.

种子梨形或很少外形不规则；种皮膜质或者薄而脆；丰富的胚乳或者不够，肉的±；胚较大，弯曲或者很少宽马蹄形；子叶平凸和线形的或多少扁平和椭圆状长圆形；下胚轴上位。

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。
