Results show stigmatic pollen load of pollinated flower is significantly higher than ovule number/ovary for all the studied plants; pollen grains deposited on stigma are enough to fertilize all of the ovules. Results also seed abortion is common.

虽然花部隔离是不完全和不彻底的，但在维持马先蒿属植物间的生殖隔离和种间特征，尤其是避免普通传粉者所造成的花粉干扰是十分重要的。

In addition, they have relatively longer flower tubes, higher stigmatic pollen loads, bigger pollen size and a shorter blooming period for individual flowers. Finally, the author discusses the evolutionary significance of floral design in genus Pedicularis.

如我们发现，由柱头特征不同导致传粉效率的差异，这种传粉效率与马先蒿属植物的花冠管成正比，与单花开放时间成反比，与花粉大小成正比，本文还着重讨论了这些相关性的适应性意义。

There are 23 species and 3 varieties Orobanche plants in China,most of which are distributed over north,northwest and northeast.The compounds of Orobanche were reported at phenylethanoid glycosides such as acteoside and isoacteoside,and acteoside has significantly protective againstα-galactose induced hepatic injury,which is better than Biphenyl dicarboxylate.

第一部分紫花列当化学成分及生物活性研究紫花列当Orobanche coerulescens Steph为列当科列当属二年生或多年生寄生草本植物，性温、味甘，生长于沙丘、干草原、砾石沙地和戈壁之中，寄生在菊科蒿属植物的根上，具有补肾、强筋之功效，用于肾虚、腰膝冷痛、阳痿遗精和神经官能症等疾病的治疗。

马先蒿属植物以其丰富的花部变异为研究植物的花部进化与传粉适应，传粉生物学以及植物的物种形成提供了理想的材料。

ABSTRACT Pedicularis species provide ideal materials to study flower evolution, pollination biology, and plant speciation for their substantial variation in floral design.

马先蒿属植物以其丰富的花部变异为研究植物的花部进化与传粉适应，传粉生物学以及植物的物种形成提供了理想的材料。

In the composite family, having green or grayish foliage and usually numerous small discoid flower heads and including the mugwort, sagebrush, tarragon, and wormweed.

蒿属植物一种菊科蒿属的带香味的植物，有绿或浅灰色叶子，常有许多盘状花，包括艾蒿，三齿蒿，龙蒿和除虫草

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。
