不育

Glumes (1–)3(–5), transitional with basal, sterile lemmas; lemma 7- to many veined, abaxially commonly puberulent and with distinct tessellation, adaxially slightly scabrous with minute setulae, apex acuminate with an awnlike point; palea conspicuously smaller than lemma or equaling in length but much narrower in upper florets, abaxially minutely setulate, 2-keeled, 2–4-veined between and beside keels, apex obtuse or emarginate; lodicules 3, membranous with thickened lower portion, 5–7-veined, margins ciliate, anterior pair of lodicules usually asymmetrical.

颖片(1-)3(-5)，基部，不育的过渡具；外稃7-在很多脉，背面通常被微柔毛并且有清楚棋盘花纹，有微小setulae，芒状点的先端渐尖正面有点粗糙；内稃显著但是非常在上面小花内狭窄的小于外稃或者等长，鳞被3，膜质具加厚更低的份，5-7脉，边缘具缘毛，前面的对鳞被通常不对称。

The pollen is malformed, unstained, and small in the KI-I2 solution. The anther dehiscence is in advance at the bicellular pollen stage.

结果表明： 1、不育花药白色，花药在二孢花粉期提前开裂；最后形成的花粉小而畸形，碘液不染色。

Chicken and quail intergeneric hybridization is a classic distant hybridization in fowl. In fowl science, chicken and quail belong to Aves, Galliformes, Phasiamidae, Gallus and Coturnix, and this hybridization combination has become the example of researching the incompatibility of different germ cell and sterile of distant hybridization.

鸡与鹌鹑杂交是属间杂交，其杂交种胚胎早期出现大量的死亡，并且杂交种出壳以前雌性胚胎全部死亡，这使鸡与鹌鹑杂交成为研究异种生殖细胞不亲和性和杂交种不育的典型。

Leaf blades on sterile branches not flabellate, longer than wide, apex acute or obtuse.

在不扇形不育枝上的叶片，长于宽，先端锐尖的或钝。

The all samples were extracted with 80% methanol and determined for contents of IAA^ ABA GA, and iPA by indirected ELISA.

结果表明：(1)在花器官中，IAA、ABA、GA_3、ZR、iPA在不育系和保持系间的变化趋势不一致，含量也有很大差异。

The heart is like shut-off of water: Can amend article of department of gynaecology, male division, infecund barren only at present, plant to the disease of other, if liver is ill,wait for me to won't make these stations.

心如止水：目前只会修改妇科、男科、不孕不育的文章，对其它的病种，如肝病等我不会去做这些站。

Style usually 2-cleft, rarely entire; stigmas 2, capitate or elongated, rarely subpeltate, or 1, 2-cleft, lower part not inflated, without sterile portion.

通常的花柱2半裂，很少全缘；柱头2，头状或拉长，很少近盾形，或1，2半裂，不膨大的下半部分，没有不育的部分。

The analysis of parents using AFLP markers showed that there were more than 3.96% background differences in heredity between parents, which were much more than theoretical value. It indicated that there was a large conservative region near male sterile genes within Tagetes erecta genome, in whichgenes are closely linked to each other.

通过AFLP标记技术对亲本的分析，发现亲本间存在不低于3.96%的遗传背景差异，远较理论值高，说明万寿菊基因组中在雄性不育基因附近存在比较大的保守区域，该区域基因间存在着比较紧密的连锁关系。

According to anther abortion characteristics and hormone functions, it was suggested that IAA, GA3 and ZR deficiency might be associated respectively with the inhibition of starch grain accumulation, pollen mother cell and tapetal cell expansion and tetrad formtion, and that abortion and even death of pollen mother cells and tapetal cells in sterile anther might be accelerated by high ABA accumulation.

根据内源激素的功能推测，不育花药IAA含量过低使花药淀粉积累受阻，GA_3含量不足影响花粉母细胞和绒毡层细胞的膨大，过低的ZR含量使花粉母细胞不能分裂形成四分体，过高的ABA含量促进花粉母细胞退化和死亡。

Paraffin slides observation found that the microspore of the RNMS line failed to vacuolate after its morphogenesis, disassembled and disappeared at last. After microspore morphogenesis, the breaking down of tapetum cells was delayed until microspore breading down.

石蜡切片细胞学观察，发现该隐性核不育能形成正常的四分体孢子，四分体释放出小孢子后，在单核花粉进入液泡化时小孢子的发育异常，不进行正常的液泡化，逐渐开始解体和消失；相应的绒毡层在小孢子形成后的降解延迟，绒毡层细胞的体积略有增大，在小孢子降解快结束时也很快解体。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
