查询词典 reproductive

The development of Peiai 64S and IR36 did not differ up to microsporocyte formation stage; but since meiosis stage, male reproductive cells of Peiai 64S underwent several structural changes and ultimately terminated by early bicellular stage.

结果表明，小孢子母细胞减数分裂之前，培矮64S与IR36的发育过程基本相似。但从减数分裂开始，培矮64S的雄性性细胞出现一些异常变化，并最终发育至二胞花粉早期败育。

RESULTS: The growth speed, weight, developmental uniformity, bionergy and fecuncity of the Bombyx silkworm descent dramatically as they eat the feed that the concentration of 2,4-DCP over 0.8 mmol L~-1 or NP exceed 0.500 mmol L~-1. But the effect on reproductive capacity vary with gender difference, it's more obvious on the late-stage of development and periods of metamorphosis such as ecolysis, pupation, edosion. There may be cumulative effect inside the Bombyx siliworm.

结果 家蚕幼虫食下含0.8 mmol·L~(-1)以上浓度的2，4-DCP或0.500 mmol·L~(-1)以上浓度的NP饲料，生长速度、生长量、发育整齐度、生命力和生殖能力都明显下降；生殖能力所受影响应性别而不同；家蚕发育后期和蜕皮、化蛹、羽化等变态时期影响更加明显，在蚕体内可能有累积作用。

The asexual reproductive eggs and larvae were obtained when 50 commercial and bivoltine races induced by hot water. But the rate of asexual developed eggs varied markedly among these races, the range was 11. 99～88. 88 percent. About one-third races, their rates of asexual developed eggs attained 70～80 percent. The rate of asexual developed eggs about hybrid was higher than its parent.

对我国50个二化性现行品种资源进行无性繁殖发生率调查，结果表明各品种都可经诱导获得一定比例的无性繁殖发育卵和幼虫，但品种间存在较大差异，其发生率范围在11.99~88.88%之间，有1/3品种的无性繁殖发生率达到70~80%，而杂交种的无性繁殖发生率明显超过原种的水平。

Seveteen fine biovotine female lines also had been bred out after 5～10 generations selecting directly to the bivoltine genetic resources, which included 8 Chinese female lines, 8 Japanese female lines and 2 hybrid female lines. These female lines could be reproduced easily by asexual reproductive way, their rate of asexual developed eggs were high with only female generations and economic characters were also stability.

采取直接利用无性繁殖性状较优良的二化性现行品种资源构建雌蚕无性繁殖系的方法，经5~10代的无性繁殖继代选择，初步育成了17个雌蚕无性繁殖品系，其中中系品种8个，日系品种7个，杂交种2个。

In terms of immunology, uterus is a special reproductive and immune organ. It shows immunological tolerance and immunological rejection respectively at the time of blastocyte implantation and parturition; blastocyte implantation is also concerned with the action of many cytokines and MMPs.

从免疫学角度来讲，母体子宫作为特殊的生殖免疫器官在胚泡着床和分娩时分别表现为免疫耐受和免疫排斥，这两个生理反转过程必然涉及基因的时空差别表达；胚泡植入又涉及大量细胞因子及基质金属蛋白酶的协同参与。

The research work can make us acquire the further recognition of molecular mechanism about blastocyte implantation and parturition and provide the theoretical basis for some leading-edge problems, such as organ transplantation, homeoclone or heteroclone. In the meantime, the result might be used as possible targets of medicine development for the cure of some reproductive diseases, such as sterility, abortion and fetal malformation.

研究这些关键过程将使我们对胚泡植入和分娩的分子机理获得进一步的认识，同时也可为器官移植、同种或异种克隆等研究热点提供基础理论依据，在临床上也为治疗一些妊娠疾病如不孕、流产、胎儿畸形等提供药物可能作用的靶位点。

In this study, real-time PCR technology was used to dectect the expression of PRL mRNA and its receptor in the reproductive tissues,which is hypothalamus-pituitary-ovary-oviduct four important tissues. The aim was to compare the difference of PRL mRNA expression in the different state of ovulatory, broody and after broody, and to analyse the relation between expression and reproduction.

本试验利用real-time PCR技术检测雪山草鸡下丘脑、垂体、卵巢、输卵管四个繁殖轴组织中PRL基因及其受体的表达量，以确定处在生产、抱窝、醒抱三个不同状态母鸡PRL基因表达的差异，并分析基因表达量的差异与生产性能的相关性。

The objective of this study is to elucidate the low reproductive ability in the Bubalus bubalis by analysis FS cDNA sequence.

本研究拟通过分析水牛的FS cDNA序列来分析其繁殖性能低的可能原因。

It was also found that there were two mutants of amino acids in this study, which may impact the normal biological function of FS, and in turn, affects the reproductive abilities in Bubalus bubalis.

研究发现两处氨基酸的突变，这可能影响FS正常的生物学功能发挥，从而影响水牛的繁殖机能。

Objective: Porcine enteric virus is a pathogen, which causing porcine enterovirus infection, such as porcine encephalomyelitis, reproductive failure, pneumonia, diarrhea, cardiopericarditis, myocarditis, dermal lesion, and so on . It is an important infection disease that can damage the pig-raising industries. In this study, porcine enterovirus was isolated and identificated in pocine kidney primary cell.

猪肠道病毒感染是由猪肠道病毒(Porcine enterovirus，PEV)所引起，有多种不同的临床表现，如猪脑脊髓灰质炎、生殖障碍、肺炎、下痢、心包炎和心肌炎、皮肤损伤及无症状等，是一种危害养猪业的重要传染病。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
