Inflorescences terminal and axillary, racemes subdigitate or axillary racemes sometimes solitary, spathate; racemes bearing pairs of unisexual awnless spikelets, female and male spikelets separated into different zones, axis fragile, especially in female zone; lateral racemes of digitate cluster entirely staminate, terminal raceme and solitary axillary racemes mixed, usually sterile spikelet pairs at base, then a zone with female sessile and sterile pedicelled spikelets, distally both spikelets of a pair staminate, uppermost spikelet pairs sterile.

花序顶生和腋生，总状花序或腋生总状花序有时单生，；总状花序着生单性awnless小穗，女性和男小穗分成不同区域，脆的轴，特别是女区域；侧总状花序的完全雄蕊花的指状簇生，顶生总状花序和单生总状花序混合，通常不育对在基部，一女的区域具无梗和不育pedicelled小穗，一雄蕊花的对，不育的最上部的小穗对的两小穗的上部的然后。

The results showed that: 1 In male sterility line and its normal variety, the change of the phytohormones contents was obvious during the whole bud development stages in fertile and male sterile lines, and the hormone contents were significant different, indicating that the reduction of the contents of IAA and GA3 and the increase of the Contents of ABA and ZR were associated with the occurrence of male sterility.

结果表明：1在花蕾的整个发育时期，不育系和可育系4种内源激素含量变化趋势差异明显，且含量高低明显不同。IAA和GA3含量的降低及ABA和ZR含量的提高可能与亚麻雄性不育的发生密切相关。2IAA/ABA、IAA/ZR、IAA/GA3和GA3/ABA在两者间的变化趋势不一致，且大小差异很大。

Objective To investigate the importance of semen examination in male infertility, and to provide evidences for the clinical therapy.

Objective To find out the station of the infecund and the can not bear patients were infected by UU and CT and discuss the meaning of diagnose infecund and can not bear using FQ-PCR.

目的 了解不孕不育患者解脲支原体和沙眼衣原体感染情况，探讨荧光定量PCR应用于诊治不孕不育的意义。

For UU' s and CT' s gene copy femate more than mate. Conclusion Infected by UU and CT is the reason causing infecund and the can not bear. UU's infections rate is more than CT's. FQ-PCR is a mean use to diagnose infecund and the can not bear for Genital infection by UU or CT.

UU和CT是引起男女不孕不育的重要原因，UU感染率明显高于CT；FQ—PCR技术应用于诊治UU或CT泌尿生殖道感染引起的不孕不育简便、快捷、安全、可靠。

The Vg-negative reaction of the triploid female rainbow trout could not provide full evidence for the impossibility of liver to synthesize Vg. That Vg was not synthesized resulted from insufficient estradiol due to the retardation of ovaries development, the un-differentiation of follicular cells and the lost interaction of germ cell and somatic cells. It could be concluded from yolk genesis that the shortage of female triploid rainbow trout's Vg resulted from the abortive ooecium, but did not result in sterility.

由于三倍体雌性虹鳟卵巢发育受阻，无滤泡细胞分化，生殖细胞与体细胞的互作缺失，不能分泌足量的17β-E2以诱导Vg的合成，因而肝脏的Vg阴性并不能说明肝脏不具备合成Vg的能力，从卵黄发生的角度分析，卵黄蛋白原的缺乏不是导致三倍体虹鳟雌性不育的原因，而是其卵泡败育的结果。

In the anthers of China CMS lines,there is normaldifferentiation of anther walls,male sterility is characterizedby the abortion of sporogenous cells and microsporemother cells.
