查询词典 vegetative leaf

In this study, a clonally propagated FT population (F2CP) including 250 stable lines was obtained by vegetative propagation of F: seeds from a cross between Japonica Balilla and Indica Dular.

以该F_2CP为研究对象，在2000年和2001年共对20个重要农艺性状进行考察和统计分析，在2001年种植F_(2：3)家系群体进行相同研究，以便比较两个群体的表现。

The studies on intraspecific variation of Batrachospermum gelatinosum and B.intortum have been made. The results show that the intraspecific variation is widespread. Most of numerical characters are in great variable range. Compared with the reproductive organs, the vegetative organs are more variable to vary.

对胶串珠藻和绞扭串珠藻的种内形态变异进行了初步研究，结果表明，种内形态变异现象普遍存在，变异范围较大的，多属数量性状，且营养结构较生殖结构特征具有更大的变异性。

The ultrastructure characters of pollen grain in Brassica napus are:1There are vacuoles in cytoplasm but no starch grain in uniceelluar pollengrain.2The veget- ative nucleus of bicellular pollen grain is generally spheroidal;while the generative cell is spinde-shaped,with a big nucleus,thin layer of cytoplasmand few cell orgens,no cell wall.3In three-celled pollen grain the sperm cell is separated from the cytoplasm of vegetative cell by two layers of plasmic membrances.

Brassica napus的花粉粒，在不同发育时期超微结构的特征如下：1单胞花粉粒有一个球形的细胞核和明显的核仁，细胞质内出现液泡，缺少典型的淀粉粒。2双胞花粉粒的营养核多为球形。生殖细胞纺锤形，无细胞壁，细胞核比例大，细胞质呈薄层，细胞器少。3三胞花粉粒有一个裂片状的营养核和两个纺锤形的精细胞，精细胞无壁，以两层质膜与营养细胞的细胞质相隔。

As might be expected, the thermal process associated with blanching is sufficient to reduce the population of vegetative microorganisms, especially those that reside on the surface of the product.

这些酶是由特殊微生物产生的，因此，这个过程的初始目的就是实现储藏稳定性，防止酶在冷藏和冷冻食品条件下或在干燥食品中仍有活性。

The life cycle of flowering plants may now be bridged at the level of free vegetative cells.

现在显花植物的&生活史&可以在游离营养细胞的水平上连结起来。

The GPA1 gene was obtained via PCR amplification and was cloned in the two-hybrid DNA binding domain vector pGBKT7 The combinant plasmid was designated as pGBKT7-Ga.β-galactosidase assay indicatedthat Got did not have the property of self-activation. After pGBKT7-Ga was transformed to yeast pJ69-4A, we transformed Arabidopsis vegetative tissue two-hybrid cDNA library plasmids to yeast pJ69-4A containing pGBKT7-Ga.

通过PCR扩增得到GPA1基因并将其克隆到双杂交DNA结合域载体pGBKT7中，得到的重组质粒命名为pGBKT7-Gα，β—半乳糖苷酶活性鉴定表明Gα不具有自激活特性，将其转化到酵母菌pJ69-4A中，再以此为受体菌转化拟南芥绿色营养组织cDNA文库质粒。

Corylus heterophylla vegetative propagation was relatively difficult, layering method was mainly used at present, but low coefficient of propagation limited mass production of its seedlings.

榛子是一种无性繁殖相对困难的树种，目前主要采用压条法进行繁殖，繁殖系数低，这限制了榛子苗的大量生产。

Stem cell research might yield ways to grow new body parts, but without a parallel curer for Alzheimer's, this wonderful new technology would do no more than allow more people to persist in vegetative states for years longer than is currently possible.

干细胞研究可能会找到新器官的培育途径，但是如果我们没有同时找到医治老年痴呆症的良方，这种奇妙的新技术无非只是让更多的人在植物状态下苟活更长的时间罢了。

Stem cell research might yield ways to grow new body parts, but without a parallel curer for Alzheimer's, this wonderful new technology would do no more than allow more people to persist in vegetative states for years longer than is currently possible.

干细胞研究可能会找到新器官的培育途径，但是如果我们没有同时找到医治老年痴呆症的良方，这种奇妙的新技术无非只是让更多的人在植物状态下茍活更长的时间罢了。

Leaves radical from vegetative stem, solitary from flowering stems, curvinerved.

叶在营养体茎上基生，在开花茎上单生，具曲叶脉。

The receding calculations and experiment analyses in this subject are built on the blood cast of pig tongue.

"Each human infection constitutes an opportunity for genetic modification of the virus through reassortment, mutation, or both...."

&每一次人类的感染都暗藏着一次基因修改的机会，无论是通过病毒的整合、突变或者兼而有之。。。。&
