| 1. | Studies on specific proteins during early stage of cucumber in vitro gynogenesis 黄瓜离体雌核发育早期的特异蛋白研究 |
| 2. | Thus , so called " allogynogenetic crucian carp " was thought as the progeny of gynogenesis 因而认为异育淇鲫是雌核发育的产物,父本遗传物质对子代无影响。 |
| 3. | This result mean that the fish obtained by the above technique treatments is real diploid mito - gynogenetic grass carp 说明这些草鱼是经过染色体加倍所得的、完全真实的雌核发育二倍体草鱼。 |
| 4. | Thirty percent of the gynogens were fertile which possessed the normal ovary and produced normal mature eggs 在第二年检测发现3070的雌核发育鱼是可育的,具有正常的卵巢,能产生成熟的卵子。 |
| 5. | Indeed , groups of homozygous diploid mitogynogenetic fry of grass carp , which is very important for both the theoretical and practical research of genetic breeding , have been produced with this techniques based on the parameters 并得到了在遗传育种理论研究和生产应用上均有重要价值的基因纯合型的雌核发育草鱼。 |
| 6. | Cytological genetic analysis revealed that the chromosome number of gynogenetic grass carp is 48 and the karyotype is 18m + 24sm + 6st , fundamental arm number ( nf ) is 90 , just as those of the common grass carp 此外,对雌核发育草鱼细胞遗传学分析证实所得雌核发育草鱼的染色体数目为48条,其核型公式为18m + 24sln + 6st ;臂数为哪习o 。 |
| 7. | The developmental procedure of first cleavage of grass carp eggs activated by uv - irradiated common carp sperm were systematically observed by method of histological section 本文用组织切片方法系统地观察了用被紫外线照射的湘江野鲤( cyprinuscarpioxiangjiang )的精子作激活源启动草鱼( ctenopharyngodonidellus )卵子雌核发育的细胞学变化过程。 |
| 8. | The mature females were only found among the two - year old gynogens , not being found among the one - year old gynogens , indicating that the ovary in the gynogens developed slowlier than that in the normal diploids such as the red crucian carp 二倍体雌核发育鱼的性成熟比普通的二倍体鲤、鱼即鱼的性成熟得晚,在一龄的雌核发育鱼没有发现达到性成熟的个体,只有到二龄时,才发行性成熟鱼。 |
| 9. | The hatching rate of the gynogens with the cold shock was higher than that of the untreated gynogens . all the gyngens with and without cold shock were examined to be diploid females with 100 chromosomes , providing the evidence that the females of the tetraploid population are homogamety ( xxx ) 冷休克处理和未冷休克处理的雌核发育鱼均是二倍体( 2n = 100 )的雌鱼,这证明了异源四倍体螂鲤是雌性的性别决定类型属于xxxx类型。 |
| 10. | It was found recently that in the gynogenetic haploid and diploid embryos of goldfish , which have exactly the same genome , the haploid condition results in obstruction of gene expression and abnormal development while the diploid embryos have normal gene expression and development 在具有相同基因组的金鱼雌核发育单倍体和二倍体胚胎发育过程中,单倍体本身的条件导致了它在基因表达上有缺陷,发育不正常,而二倍体发育正常。 |
