查询词典 sepals

Sepals acute, acuminate, or obtuse apically, mucronulate or not, not long attenuate, herbaceous, membranous, or leathery; corolla reddish, purplish, lilac to pink, or white.

锐尖，渐尖的萼片，或钝顶部，与否具小短尖，渐狭，草质的长的不，膜质，或革质；花冠带红色，略带紫色，淡紫色的到粉红色，或白色。

Sepals rounded to acuminate, emarginate, or mucronulate but never awned at or near apex; corolla mostly funnelform, or campanulate, sometimes salverform; stamens and pistil mostly included, sometimes exserted.

萼片圆形的到渐尖，微缺，或具小短尖但是从未具芒的在先端或近先端；多数漏斗状的花冠，或钟状，有时高脚碟状；雄蕊和雌蕊多数内藏，有时。

Stems simple or multibranched; leaf blade lanceolate or elliptic-lanceolate to ovate, 5-10 mm wide; racemes opposite to leaves or axillary; bracts ovate-lanceolate, caducous; inner sepals obovate-oblong.

茎单生或多分枝；叶片披针形的或椭圆形披针形到卵形，5-10毫米宽；总状花序与叶对生或腋生；苞片卵状披针形，早落；内部萼片倒卵状长圆形。

Sepals glabrous, sometimes muricate or dentate on veins.

萼片无毛，有时或具牙齿在脉上。

My thesis is to examine the correlation between the formations of petaloid sepals in Mussaenda and the petal identity genes, i.e. ABE class genes.

本论文即以玉叶金花属植物为材料，观察此一类花瓣构造的形成是否与花瓣决定同源基因的异位表现相关，进而探讨其背后的遗传控制机制。

Though there might be other factors involved, results suggest the formation of petaloid sepals in Mussaenda still required A, E, and some B class genes, but further survey for addition factors and functional assay for identified genes are needed.

以上结果显示玉叶金花类花瓣花萼的发育过程可能有A群、E群及部分的B群基因参与调控，虽不排除有其他因子参与的可能性，但其调控机制是否能以现有的模式解释尚待更进一步的研究。

The enlarged showy calyx-lobes in Mussaenda are good examples. The calyx-lobes, so called calycophylls, are mostly leaf-shaped, but have bright color, papillate epidermis, and loose mesophylls, features generally only found in petals. In higher eudicots, floral organs are typically arranged in four different whorls, namely sepals, petals, stamens and carpels.

自然界中有钗h植物以一整个花序替代一朵花作为传粉的单位，而在这样的花序中常常会有某些构造花瓣化来替代原来花瓣的弁遄C玉叶金花是一个非常有趣的例子，这一属的植物常具有膨大的花萼裂片，其形状类似叶子但多具有鲜艳色彩，且细胞形态及细胞排列均相当类似於花瓣，在弁鄐W一般均认为与花瓣无异。

Petals 6, nectariferous, much smaller than sepals or absent.

花瓣6，分泌蜜汁，比萼片小得多或者无。

Leaves all basal, simple, 3-sect, or ternate; petals ca. 1/3 as long as sepals, not petaloid (instead specialized nectariferous organs); style ca. 2 × as long as ovary; follicles cubic-globose

叶全部基生，单，3裂，或三出；花瓣约1/3倍于萼片，不瓣状(代替为特化的分泌蜜汁器官)；花柱长约2 *倍于子房；蓇葖果立方球状 18 Urophysa 尾囊草属

Petals purple, lavender, or white; blade obovate or narrowly obcordate, apex rounded or emarginate; claw obscurely to strongly differentiated from blade, shorter than to as long as sepals.

花瓣紫色，淡紫色，或白色；叶片倒卵形或者狭倒心形，先端圆形或微缺；瓣爪不明显到强烈与区别的叶片，对倍于萼片的短于。

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。
