多育的

The new materials(N/BBCC and J/BBCC) and their transmigration parent put up the similar phenotypes in development stage,morphological characters,POD enzyme activity,and so on.But differences in male fertility,proline content and relative conductance rate were existed among them,in which the development of androecium in N/BBCC was abnormal,showing serious male sterility,and the proline content and relative conductance rate in N/BBCC and J/BBCC were much lower than their transmigration parent,C/BBCC.

两个新材料及其轮回亲本C/BBCC在生长发育时期、植株外部形态特征、POD酶活性等方面表现基本一致，但在雄性育性、脯氨酸含量及相对电导率上存在着明显差异，其中N/BBCC雄蕊发育不完善、花药瘦小、药内花粉量很少且多为无生活力的畸形花粉，表现严重败育；J/BBCC和N/BBCC的脯胺酸含量及相对电导率明显低于其轮回亲本C/BBCC。

The factors affecting the seed-set rate ofintersubspecific hybrids include embryo sac sterility,pollen sterility,anther dehiscence and non-synchronization of male and female sexual organsdevelopment in the same spikelet.

对水稻亚种间杂种及其稳定的多胚品系SB-1进行了细胞学、胚胎学和遗传学研究，主要结果如下：1、影响杂种低结实率的因素包括胚囊败育、花粉败育、花药不开裂和雌雄性器官发育进程不一致。

Megaspore development and abortion of"Pingyi Tiancha"Compar-ing with regular developing megaspore of normal M.baccata,the megasporemother cellof"Pingyi Tiancha"could form mono-nucleus embryo sacby perhaps irregular meiosis,then most of sexual MES depauperatedand degenerated,finally aborted,or only a few further developed.Of asexualembryo sac,one or more large cells at the chalazal end of nucellus developed in-to one to more asexual embryo sac initials.After the competition between sexu-al embryo sacand asexual embryosac,most ovules only had one asexual embryo sac matured.

平邑甜茶大孢子的发育和败育与正常发育的山定子大孢子对比，平邑甜茶大孢子母细胞经减数分裂能形成单核胚囊，之后多数有性胚囊萎缩、退化而败育，只有极少数进一步发育；而无性胚囊则从胚珠合点端1个或多个较大的珠心细脆形成并首先发育为一个或多个无性胚囊原始体；经过有性胚囊和无性胚囊以及无性胚囊和无性胚囊之间的竞争，多数胚珠只有一个无性胚囊成熟。

Though carbohydrate metabolism in induced or natural diapaused eggs was the same, the heredity of the induced diapaused eggs experienced no change. The eggs of next generation were still non-diapaused. This is of significance for long-term conservation of polyvoltine silkworm eggs.

本研究还发现诱导滞育卵的碳水化合物代谢虽然与自然滞育卵相同，但其遗传性并未改变，下一代产下的卵仍然是非滞育卵，这对多化性品种的长期保存有重要意义。

Spermatogenesis education isthe seminal vesicle for the same spermatocyst, the size of the nucleus is very similar tochromosomal changes, and the developmental level coincide.

拟黑多刺蚁精子发生是以育精囊为单位进行的，同一育精囊的生精细胞形态、大小以及细胞核内染色体变化极其相似，发育水平比较一致。

Analysis of fertility segregation pattern from F1, F2 and BC1 indicated that the sterility trait of 0A15-1 was controlled by a single recessive gene and belonged to sporophytic male sterile type.

通过与明恢63、优B和广陆矮等多个父本的杂交，其F2和BC1群体的育性分离比都揭示0A15-1的不育性状受一对隐性核基因控制，并且为孢子体型雄性不育。

Yo green jade is right " Persia is princely " make newly take seriously very, brought many manpower material resources into play, development group member reachs 140 people, having a lot of people is to come from the Yu Yobi's other group that make.

The cytoplasmic male sterile line CMS96 was transferred into Chinese cabbage by hybridization and subsequent backcrosses using CMS donor of B.napus.

大白菜CMS96细胞质不育系是由大白菜株系与甘蓝型油菜细胞质不育源杂交、多代回交后获得的。

The results indicated that more Ca〓 in sterile anthers might be related with its abnormality of function.

由此看出不育系花药维管束中有较多的Ca〓与其结构功能的失常及雄性不育性产生有一定关系。

All of the sterile pollens possessed malfunctioned exine.
