雌雄

An inflorescence with the pistillate flowers borne above the staminate, as in some Carex species.

雌雄同序的 Gynaecandrous 雌花着生部位高于雄花的花序，如苔草属的某些种。

Even though the change pattern of protein content was similar, its occurrence is much earlier in staminate than in pistillate plants.

杜仲雌雄株树皮中的蛋白质含量变化趋势基本一致，但雄株发生变化的时间比雌株早。

The factors affecting the seed-set rate ofintersubspecific hybrids include embryo sac sterility,pollen sterility,anther dehiscence and non-synchronization of male and female sexual organsdevelopment in the same spikelet.

对水稻亚种间杂种及其稳定的多胚品系SB-1进行了细胞学、胚胎学和遗传学研究，主要结果如下：1、影响杂种低结实率的因素包括胚囊败育、花粉败育、花药不开裂和雌雄性器官发育进程不一致。

In conventional sexual hybridization of citrus, nucellar polyembryony, pollen/ovule sterility, genetic heterozygosity, wild sexual incompatibility of most citrus cultivars make it very time-consuming and low efficiency to improve fruit characters.

但是，由于柑橘类植物中存在的珠心胚现象、一些品种中的雌雄性败育、童期过长、远缘有性杂交不亲和等特点使通过传统的有性杂交方式进行品种改良进程缓慢，效率不高。

Results There was a dose-response relationship between concentration of ponceau 4R and mortality rate of drosophila in acute toxicity test.

结果急性毒性试验中，胭脂红浓度与雌雄果蝇的死亡率呈剂量-反应关系。

The SOD activity decreased and MDA concentration increased significantly （P〈 0.05 ） with prolonged exposure and increased concentration of ponceau 4R, that was fitted with a time-dose-response relationship.

随着胭脂红染毒时间的延长和染毒浓度的增加，雌雄果蝇体内SOD活力明显下降、MDA含量明显升高（P〈0.05），呈剂量-反应关系。

To examine the significance of heat shock protein 70 mRNA in ototoxicity resulted from gentamicin, twenty healthy albino guinea pigs (200~250 g) of either sex with a positive Prier reflex were divided into two groups randomly.

摘 要：为探讨热休克蛋白(heat shock protein， HSP) 70 mRNA在庆大霉素(gentamicin， GM)耳中毒中的意义，本实验选用耳廓反射灵敏的健康白色红目豚鼠(200~250 g) 20只，雌雄不拘，随机分成两组，每组10只。

The female and male pronucleus formed and fused about 45～50 min after insemination.

授精后约45～50 min雌雄原核形成，并相互融合。

And the male pronucleus moved to the female pronucleus during the period of associating of the two pronucleus.

并且在系列的样品中可观察到，在雌雄原核联合的过程中具有雄性原核向雌性原核移动的趋势。

In homosporous plants, there is only one type of prothallus with both male and female sex organs.

在具同形孢子的植物中，只有一种雌雄性器官兼备的原叶体类型。

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。
