萼片的

Its results showed that ratio of length to width of petal and sepal and the degree of flat of achene within population were characterized as the most stable characters and gradually increased with the increase of latitude.

结果表明，居群内，瘦果扁平度、花瓣长宽比、萼片长宽比变异最为稳定，居群间，这3个繁殖器官的相对性状呈现随着纬度的增加逐渐增大的趋势，并且随纬度的增加，核型不对称系数呈现不断增加而染色体总长不断减小的趋势。

We explore these questions in Legume model system, Lotus japonicus. Compared with model plants Antirrhinum and Arabidopsis, floral pattern formation of Lotus japonicus is different in several aspects. Floral organs initiate in an order of sepals, carpel, petals, stamens. Within each whorl, organs initiate unidirectionally from ventral side to dorsal side. Initiation of organs in different whorl overlaps. Stamens exist in both 2nd whorl and 3rd whorl, and 2nd whorl is heterogeneous for the existence of different identity organs .

与模式植物金鱼草和拟南芥相比，豆科模式植物百脉根的花模式建成有其特殊性：一、花器官从腹部向背部单向起始；二、器官起始顺序是萼片—心皮—花瓣—雄蕊；三、不同轮的器官起始时间相互重叠；四、相同属性的器官出现在不同轮中；五、第二轮不均一，出现不同属性的花器官；六、花瓣和雄蕊不单独起始，而是经过了短暂的花瓣—雄蕊共同原基的阶段。

The lack in Galitzkya of simple and forked trichomes and staminal appendages, and the development of thick, branched caudices and saccate, lateral sepals clearly distinguish it from Berteroa .

在单和分叉的毛状体和雄蕊的附属物的Galitzkya里的缺乏，后面属有单和分叉的毛状体，雄蕊的附属物和无气囊的萼片。

Petals golden yellow, not tinged red, oblong-obovate to broadly obovate, 1.2-1.8 × 1-1.4 cm, 1.5-2 × as long as sepals; margin entire or slightly eroded-denticulate with row of intramarginal gland-dots; apiculus rounded to obsolete.

花瓣金黄色，不微染红色，对宽倒卵形长圆状倒卵形， 1.2-1.8 * 1-1.4 厘米，1.5-2 *等长于萼片；边缘全缘或稍具细牙齿腐蚀的的具成排的近边缘内的腺体小圆点；细尖的圆形到废退。

The results indicated that along with the increase of chilling requirement of varieties, each differentiation stage for different varieties was delayed, the sepal differentiation stage was extended, the pistil differentiation stage was shorten. The time difference of petal and stamen differentiation stages was little among different varieties.

结果表明：随着品种需冷量的增加，不同品种花芽分化的各个阶段开始的时间有所推迟，萼片分化期所用的时间逐渐延长，雌蕊分化期所用的时间逐渐缩短，而花瓣和雄蕊分化期所用的时间差异不大。

Sepals distinctly awned at or below apex; corolla salverform with a long narrow tube; stamens and pistil mostly exserted.

等于或低于顶具芒的清楚的萼片；花冠高脚碟状的具一长的狭窄的筒部；雄蕊和雌蕊主要外露。

Sepals dark-gland-fringed or, if entire, then acute or leaflike

花被管12-35毫米；萼片5-25毫米；花瓣5-25(-35)毫米；花药在花期包围的柱头；约的花粉50%的可育；主要的花自花传粉 5

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
