不败

The sterile line of Zhenshan 97A, Baoyuan A, g37A and Peiai64S had more Ca〓 precipitatesthan those in the fertile anthers since the pollen mother cell stage (which were mainly deposited in the epidermis, endothecium and vascular bundle).

野败不育系珍汕97A、包台型不育系包源A及温敏核不育水稻培矮64S和无花粉型不育系g37A的花药均从花粉母细胞时期开始出现较多的Ca〓沉淀，主要分布在药壁外层、药室内壁和药隔中。

But they were partial sterile, had 1～4 pollen sacs in each anther and had relative bigger petals and stamens at lower temperature situation. The RGCMS plants were complete sterile at the both temperature situations, and there was no pollen sac differentiation and had smaller peta...

表现核质不育的植株，在高温条件下，花瓣小，表现彻底的polCMS不育，无花粉囊的分化；在低温条件下，花瓣变大，也表现彻底雄性不育，具有核、质不育的共同特点，每个花药可分化出 1～ 4个花粉囊，但无可育花粉，其雄性败育时期和特点与S45A和 117A相同。

The DGCMS plants were complete sterile at the both temperature situations, and there was no pollen sac differentiation and had smaller petals and stamens at the higher temperature situation, but there were 1～4 pollen sacs in each anther and had bigger petals and stamens at the lower temperature situation. The cytological characteristics of the anther development were the same as that of GMS plants in Yi-3AB.

表现质核不育的植株，在高温条件下，花瓣小，表现彻底的pol CMS不育，无花粉囊的分化，在低温条件下，花瓣变大，也表现彻底雄性不育，具有核、质不育的共同特点，每个花药可分化出1～4个花粉囊，但无可育花粉，其雄性败育时期和特点与宜3A相同。

This paper summarized the experiments which support or negate the existence of female sterility,analyzed the experimental ideas and inference methods of these experiments,especially Sano' s;and concluded that the conclusion that the hybrid sterility is only caused by male or female sterility is a one - sided view,therefore attention should be paid to the genetics of both female and male sterility.

本文对证明水稻亚种间杂种存在和不存在雌性不育的研究进行了综述与分析，从中可以看出无论是认为水稻亚种间杂种不育性表现为雄性不育还是雌性不育的结论都有一定的片面性；尤其是Sano证明基因座S-5不存在的研究存在较大的缺陷。因此，水稻亚种间杂种雌雄配子败育对小穗育性影响的大小有待进一步研究。

is that Tai Yu-D2 male sterile lines abortion occurs in monokaryon stage, the tapetal expanding abnormally occurs in dyadphase stage, pollen aborts completely, is a type of no pollen.

泰玉D2不育系花药绒粘层在二分体时期成辐射状膨大，小孢子在单核期败育，花粉败育完全，属无花粉类型。

Microscopic observation of microsporogenesis of the male sterile lines revealed that abortion occurred mononuclear stage. The tapetal cells became higly vaculate, pressing the microsporocyte seriously, interfering the normal microsporpgenesis development and finally leading to pollen grain abortion.

进一步对其细胞形态学进行观察结果表明，ogura和改良型不育系败育时期发生在单核花粉期，绒毡层异常膨大，挤压小孢子正常发育，小孢子液泡化而导致败育，并且在花药发育过程中有一些异常现象发生。

Experimental results show that there are existing some indifferent mechanisms to the pollen sterilization of the Ms types: during the period of single nucleic to three nucleic pollen cell,we observed that the cell of xylem and phloem in anther septum abnormally developed,also the cell in the sheath of vascular bundle,smaller and arranged irregularly; the metabolic block developed too,es...

结果表明，不育类型的花粉败育有着一些共同的机理：在花粉单核期至三核期可见到花药隔维管束的木质部及韧皮部细胞发育较差，维管束鞘细胞发育不良，体积较小，排列紊乱；在单核花粉期至三核花粉期均发生物质代谢障碍，特别在花药部位尤为明显；由于维管束发育不良和花药物质代谢障碍，导致了花粉缺乏营养而败育。

These results indicated that the 1600 bp band derives from CMS mtDNA and can be used as a RAPD marker to distinguish A and B plants at seedling stage,and the bands other than the 1600 bp can be used to distinguish WA and DA cytoplasms.

这些结果表明1600bp带源于线粒体DNA，可用作苗期鉴别不育系和保持系的RAPD标记；1600bp以外的带可用于鉴别野败细胞质和矮败细胞质。

The sterile pollens were very concerned with non-equality of homologouschromosomes at two polars,and the difference of pollen yields among individuals werelikely related with disintegration of Tapetum in Prophase I.

其中败育花粉的产生与同源染色体的不均衡分配关系最为密切，而花粉产量的差异则可能是在减数分裂前期I时即发生绒毡层解体而造成的，其根源仍在于毛白杨染色体的异源性，此外易位、倒位等染色体结构变异和天然三倍体的存在也常常会加剧人们对毛白杨配子败育严重的印象。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
