花药的

All characters that have been used to delimit more narrowly defined species in other treatments of Chinese Clethra exhibit a strongly continuous pattern of variation from west to east across the range of the species in China (i.e., leaf size and shape, the number of secondary veins on each side of the midvein, anther size and shape); they also exhibit geographically correlated or seemingly random patterns, but without correlated gaps in character states among any two or more characters (i.e., style pubescence, corolla abaxial surface, stamen exsertion).

用来界定更狭窄定义的中国的Clethra的其它种的全部特征，从中国种的分布区的西部到东部，展示了一种强烈的连续变异的样式（如，叶大小和形状，中脉每边次脉的数目，花药的大小和形状）；他们还展示出地理分布的相关或好像随机的样式，但是在任何2或更多特征状态间没有相关的特征间隔（如，花柱被短柔毛，花冠背面、雄蕊伸出）。叶大小与形状，在中脉，花药大小与形状的每边次脉的数量；也的他们展览好象地理上有相互关联或随机模式，但是没有有相互关联特征差距在任何2 特征或更多中说明即，花柱短柔毛，花冠背面，雄蕊exsertion。

Three group male sterile and maintenance lines of monogerm sugar beet as materials were used, we observed the biological characters of their buds, anthers and anther structure, and the development process of pollens by the methods of conventional Paraffin Slicer, Safranine Ai-Shi Haematine Crystal and Fast Green.

方法］以3对单胚型甜菜雄性不育系和保持系为试验材料，采用常规的石蜡切片方法，对花蕾和花药的生物学特性以及花药结构、花粉发育过程进行比较。

Connective of anthers not subulate, not spirally twisted.

花药的药隔不钻形，不螺旋扭曲。

Stamens 8 or 10(or 12), equal; filaments short; anthers oblong or 3-sided, small, longitudinally dehiscent; connective decurrent and inflated, usually conic, 2-3 × as large as anthers or not appendaged.

雄蕊8或10(或12)，等长；花丝短；花药长圆形或者3边，小，纵向开裂；药隔下延和膨大，通常圆锥形，附属物为花药的2-3 倍或无。

Dorsifixed A stamen in which the filament is fused to the back of the anther.

背着的：是一种雄蕊花药的着生方式，指花丝与花药在背部联合。

Stamens inserted on corolla, included to exserted, equal in number to corolla lobes and alternating with them or sometimes fewer; filaments free, much shorter to much longer than anthers; anthers basifixed, 2--4-locular, dehiscing introrsely or extrorsely by longitudinal slits, base slightly to deeply parted.

雄蕊在花冠上着生，内藏或外露，与花冠裂片同数，与其互生和有时较少；花丝离生，对远长于花药的非常短；花药基着，2-4室，开裂内向或向外地以纵裂缝，基部稍在深裂。

The results showed that all contents were lower in male sterilie anthers than in fertilisable ones.With anther developing,the contents of soluble starch,protein and free proline increased obviously in male fertilizable anthers,but not in sterile ones.

结果表明：太空诱变处理玉米核不育材料的可育株花药中的可溶性糖、淀粉、蛋白质以及游离脯氨酸含量均高于不育株花药的，且可育株花药中的可溶性淀粉、蛋白质和脯氨酸含量都随着花药的发育逐渐累积，在不育株花药中这些指标的变化不明显。

The contents of soluble sugar , starch , protein and free praline in anthers were analyzed and compared between male fertilizable and male sterilie induced by space flight at different developmental stages .

为探讨太空诱变处理玉米核不育材料的可育株，不育株花药的生理生化特性差异，对可育，不育材料不同发育时期花药的可溶性糖，可溶性淀粉，蛋白质含量以及游离脯氨酸含量进行了测定。

Under low temperature condition, fertility restoring, anther developing normally, the tetrads formed after archesporical cell, sporogenous cells and microspore mother cell. Subsequently, microspores were free from the tetrad of fertile anther and formed mature pollen grains, tapetumof the fertile anthers began to disintegrate and disappear at last.

在低温处理条件下，育性恢复，花药发育正常，经过孢原细胞期、造孢细胞期、花粉母细胞期后，可以顺利形成四分体，可育花药的四分体可以释放出小孢子并发育为成熟的花粉粒，同时绒毡层细胞开始解体，最后消失。

The result is consistent with previous studies. Whereas, tapetal cells of sterile anthers were disintegrated since tetrad cells were disjoined, indicating that disintegration of tapetal cells is earlier occurred in sterile anther than that in fertile anther. DNA ladder revealed that the cleavage of nuclear DNA into oligonucleosome-sized fragments to

结果表明，在花粉母细胞减数分裂后的四分体解离时期，不育花药的绒粘层细胞较可育花药提前开始裂解；在不育系S-Mo17rf3rf3花药和花粉S-(rf3)中均明显出现PCD过程的DNA片段化以及线粒体细胞色素C外渗的现象，证明了玉米CMS-S的花粉败育与花药绒粘层细胞的提前凋亡和小孢子细胞的细胞程序性死亡有关。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
