不育

CMS as sterile cytoplasm of-ferer and Chinese cabbage as its accepter,the alloplasmic male sterility line CMS3411-7 in Chinese cabbage have been obtained by interspecies cross and continuedbackcross with Chinese cabbage 3411-7,so 3411-7 was its maintainer line.

The many hybrid wheat combinations were bred by 4 male sterile types of alloplasmic wheat with Ae.kotschyi,Ae.variabilis,Ae.ventricosa and Ae.bicornis cytoplasms and some restoring lines,and their seed qualities were analysed.

利用具有粘果山羊草(Ae.kotschyi)、易变山羊草(Ae.variabilis)、偏凸山羊草(Ae.ventricosa)和二角山羊草(Ae.bicornis)异源细胞质小麦雄性不育系(以下简称粘、易、偏和二角型)组配成不同组合的杂种小麦，研究这4种不育系对杂种小麦籽粒品质的影响。

When seedling of corn inbreds were inoculated with isolates 76-527,76-528, 76-529 of Helminthosporium maydis in the greenhouse, the seed-lings of inbred lines with T male sterile cytoplasm were more susceptiblethan those with normal (non-sterile) cytoplasm.

从我国不同地区采集的玉米小斑病菌，通过温室苗期接种鉴定，及其产生的毒素对玉米种子根的抑制作用，发现76-527、76-528和76-529三个分离菌系在T型细胞质雄性不育系幼苗上产生萎蔫型大病斑，而在相对应的正常系以及M、C、CA、EK、D、PS型细胞质雄性不育系幼苗上则产生坏死型小病斑。

Compare to K type no.1B/1R male sterile line KTSP3314A,homotypic maintainer line TSP3314B and 1B/1R male sterile line K3314A,homotypic maintainer line 3314B at different developmental stages of superoxide dismutase,catalase,peroxidase activity and variety of malondialdehyde content.

利用K型非1B/1R类型小麦雄性不育系KTSP3314A，其同型保持系TSP3314B，以K型1B/1R类型小麦雄性不育系K3314A、其同型保持系3314B为对照，分别对其叶片和穗子在不同发育时期的超氧化物歧化酶、过氧化氢酶、过氧化物酶的活性和丙二醛含量的变化进行测定。

Objective To find out the station of the infecund and the can not bear patients were infected by UU and CT and discuss the meaning of diagnose infecund and can not bear using FQ-PCR.

目的 了解不孕不育患者解脲支原体和沙眼衣原体感染情况，探讨荧光定量PCR应用于诊治不孕不育的意义。

For UU' s and CT' s gene copy femate more than mate. Conclusion Infected by UU and CT is the reason causing infecund and the can not bear. UU's infections rate is more than CT's. FQ-PCR is a mean use to diagnose infecund and the can not bear for Genital infection by UU or CT.

UU和CT是引起男女不孕不育的重要原因，UU感染率明显高于CT；FQ—PCR技术应用于诊治UU或CT泌尿生殖道感染引起的不孕不育简便、快捷、安全、可靠。

The aroma gene between Luxianghui 1 and 2 aromatic CMS lines were mutual isogenic genes, but was not isogenic to that of four aromatic CMS lines.

泸香恢1号与2个不育系的香味基因相互等位，但与4份不育系确的香味基因不等位。

To understand the CMS mechanism caused by unedited form of atp9 deeper,atp9 gene was cloned from three sterile tobacco lines and their isogenic fertile lines.

植物雄性不育最常见的是细胞质雄性不育，它在雌花两性花异株种类的进化中起到积极作用(Budar等，2001)。

There are many factors resulted in male infertility. Majority is associated with sperm count, morphology and motility. Men with oligospermia, asthenospermia, teratozoospermia and azoospermia account for 20~25% of the cases.

引起男性不育的因素有很多，大部分与精子的数目、形态及运动功能有关，其中由于精子生成过程的停滞或障碍所导致的少精子、弱精子、畸形精子和无精子症占男性不育的20～25％。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
