雌雄生殖

Apomixis provides a unique opportunity to fix and utilize hybrid vigor. A number of research programs around the world have tried to use apomixis as an important plant-breeding tool.

无融合生殖是指不经过雌雄配子融合而产生种子的一种特殊生殖方式，能使基因型的杂合性得以保持，从而可以固定杂种优势，对作物育种具有极其重要的意义。

The result of ISH indicate that the FIE gene has specialspatio-temporal expression in apomixis E.binata during the reproduction growth andcontrols the development of embryo and endosperm.

原位杂交的结果表明FIE在龙须草生殖发育的过程中特异的时空表达，与雌雄配子体发育有关，并参与调节胚和胚乳的发育。

On the basis of reviewing the resource status of Cycas guizhouensis in Guizhou province,the reproductive biology of this species including female/male ratio,pollination mechanism,characteristics and germination of seed,seed dispersal and natural regeneration ability were described.

在对贵州苏铁的分布及资源现状作出评述的前提下，从其植株的雌雄比及其传粉机制，种子的特征及其萌发与生长，种子的传播与其自然更新能力等方面，论述了贵州苏铁的生殖生物学特性。

A variety of factors can distort normal sexual development thereby giving rise to various forms of abnormal genitalia or intersexuality.

种种因素干扰正常的性别发育，产生范围广泛的生殖畸形或雌雄间性。

We herein report two cases of goats with sexual deformity.They had two systems of reproductive organs and the karyotype analysis showed mosaicism for their sex chromosomes,i.e.,60,XX / XY.The proportion of XX cell line was 42% and 54%,while XY cell line was 58% and 46%,respectively,in the two abnormal goats.

本文报道2例两性畸形的山羊，它们均具雌雄两套生殖器官，染色体组型分析显示它们均为性染色体嵌合体，核型为60，XX/XY，两头畸形山羊的XX细胞系的比例分别为42%和54%，XY细胞系的比例分别为58%和46%。

Both female and male conceptacles open to the exterior via a pore, the ostiole.

雌雄性生殖窝均通过小孔与外界相联系。

Having male and female reproductive structures on the same thallus,as in some fungi and algae .

同宗配合的在同一菌体上有雌雄两种生殖结构的，如某些真菌和藻类

But through has the actor\'s wig to the cover and does not cover two kind of processing Dactylopius confusus\'s bosom egg quantity dissection result analysis which the actor\'s wig grows naturally to be possible to know,grain\'s reproduction way is the sexual reproduction,and is through spawns the hatching,but is not the viviparity.

而通过对罩有网纱进行单雌饲(来源：AdfBCd7论文网www.abclunwen.com)养和不罩网纱雌雄自然种群混合饲养的两种处理的胭脂虫的怀卵量的解剖结果分析可知，胭脂虫的生殖方式是两性生殖，并且是通过产卵繁殖的，而不是卵胎生。

The results showed that there was no remarkable difference of reproductive hormone between the idiophase and non-idiophase, which established the theory foundation for the reproductive endocrinology and the artifical breeding of Andrias davidianus, was made.

实验结果表明，雌雄性中国大鲵在繁殖期间与非繁殖期间的6项生殖激素检测结果没有明显的差异，对中国大鲵血清中的生殖激素与繁殖期的相关性进行了初步探讨，为中国大鲵生殖内分泌学的研究和人工繁殖积累了资料。

ERAF17 gene expresses differently between male and female reproductive organs. Its expression is induced by ethylene or ethylene released compounds that can promote femaleness. No evidence directly shows the relationship between ERAF17 gene and femaleness, however. So this work focus on proving the positive correlation between the expression of ERAF17 gene induced by ethylene and development of female flowers,then search for the signal pathway of cucumber female reproductive organ development.

ERAF17基因在黄瓜的雌雄生殖器官的表达不同，可以由乙烯诱导表达，从而推动雌性化，但是它的作用机制却不清楚，并没有明确的证据表明ERAF17基因与雌花的发育有直接关系，所以本论文研究重点在于证明乙烯诱导ERAF17基因的表达对黄瓜雌花的分化有确定的正相关，从而可以探索黄瓜雌性器官发育存在的可能的信号通路，并对应用前景进行评估。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
