2023年4月18日,南京农业大学杨守萍教授团队在《Plant Biotechnology Journal》上在线发表了题为“The miR156b-GmSPL2b module mediates male fertility regulation of cytoplasmic male sterility-based restorer line under high-temperature st...
Growth factors play an important role during early ovarian development and folliculogenesis, since they regulate the migration of germ cells to the gonadal ridge. They also act on follicle recruitment...
Behaviors, morphologies, and genetic loci directly involved in reproduction have been increasingly shown to be polymorphic within populations. Explaining how such variants are maintained by selecti...
A synthetic strain of ducks (Anas platyrhynchos) was developed by introducing genes for long duration of fertility to be used as mother of mule ducklings and a seven-generation selection experiment wa...
A non-traditional forage-based protocol was employed to evaluate replacement heifer growth, fertility, and economics between small frame (SF, 3.50; n = 50) and large frame (LF, 5.56; n = 50) heifers u...
A Review on Possible Influence of Clays and Soil Clay Minerals on Soil Fertility.
Mineralogical Considerations in Soil Fertility Management n Selected Farmlands in Limpopo and Northwest Provinces,South Africa.
The Institute for Reproductive Sciences – a new centre for cutting-edge research into causes of infertility and assisted reproduction techniques such as IVF – has opened on the Oxford Business Park in...
This paper generalizes the model introduced by Cai in [5], where the Cass-Koopmans optimal growth model has been extended to allow for endogenous fertility choice. A sufficient condition for the exi...

In the present investigation, the effect of maleic hydrazide (MH) has been studied on seed germination, mitosis, and pollen fertility of Trigonella foenum-graecum L. to test its cytotoxicity. Six diff...
摘要通过2n=50和2n=49两种核型三品种杂交水牛繁殖记录分析和其中2n=49三品种杂交水牛联会复合体及其精子染色体研究,结果表明,后者虽然公母都是可育的,由于它产生两种正常配子(n=24,n=25)和两种异常配子(n=24+1,n=25-1),自群繁殖导致其子代染色体多态性(2n=50,2n=49和2n=48);其异常配子,与正常配子结合,则产生非整倍性,致其繁殖力降低,表现为情期配种受胎率降...
专著信息 书名 A synthetic gonadotropin-releasing hormone (GnRH) vaccine for control of fertility and hormone dependent diseases without any adjuvant. 语种 英文 撰写或编译 作者 Jinshu X,Jingjing L,Duan P,Zheng Z,Ding M...
The study was conducted on 30 true acyclic Sahiwal cows (15 cows, ??0 days postpartum; 15 postpubertal heifers, ??0 months of age) and a similar 20 untreated controls (10 cows, 10 heifers). An ??Eazi?...
Seven yak bulls were placed in pastures with the cows for natural mating. Estrus rate in the CPP group (28/28) was higher (p<0.01) than in the PP group (6/21) and in the CG group (0/26) within 96 h af...
