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。

The current pattern of flower variation in Pedicularis does not correspond with their single and exclusive bumblebee pollinator. New insight is needed to understand the relationship between flower evolution and pollination adaptation.

这种花部分异的现状与其几乎专一性的由熊蜂传粉极不相称，因此一直驱使人们去理解该属植物花部变异的动力和选择压力以及独特的传粉适应模式。

Pedicularis plants and their pollinators are interdependent in terms of corolla structure, pollinator behavior and caste, and blooming phenology. Species with different floral design have different pollination syndrome.

不同花部特征的马先蒿具有不同的传粉综合特征，马先蒿植物的花部特征与传粉昆虫的行为，与开花物候和传粉者阶层之间存在复杂的相关性。

Results indicate that the stigmatic surface morphology of Pedicularis species is related to the type of corolla structure occurring in the species. Pollination studies in 8 Pedicularis species demonstrated adaptation between stigmatic surface morphology and other aspects of floral biology.

拥有更膨大，更粗糙的柱头表面特征的植物种类通常都是具喙或长管种类，而短管无齿种类的柱头平滑且无膨大，相反，对于长管具喙种类而言，柱头在膨大的同时，更形成了发达的&沟回&结构，这种柱头结构式样的不同直观、显著的改变了不同种类的传粉效率。

Pollen grains germinated soon after pollination. Pollen tubes grew first into the intercellular space of branched penniform stigma and then through the intercellular space of transmitting tissue into the top of the ovary, further penetrating the ovary wall and primine to the micropyle. Green fluorescence was found in both pollen and pollen tubes.

结果表明：授粉后，花粉随即萌发，花粉管进入羽毛状柱头分支结构的细胞间隙，继续生长于花柱至子房顶部的引导组织的细胞间隙中，而后进入子房，在子房壁与外珠被之间的缝隙中向珠孔方向生长，花粉与花粉管均具有明显的绿色荧光。

Farm. In the past (until app. 25 years ago) pistachiodiversity was maintained high in the field through a number of cultivation practices, s.a. use of male varieties derived from seed, use of wild Pistacia species to boost pollination and hence the fruit setting, use of natural populations of wild Pistacia (P. atlantica) as rootstock due to their well known resistance to stony and calcareous soils.

最近在农场栽培无花果技术的改变更加导致作物的多样性减少。25年前，无花果多样性通过多种栽培保持在很高的水平（源于种子的雄性物种采用，野生开心果物种改善授粉的采用，自然野生开心果作为根茎的采用——因为他们已知很好的抵抗多石和石灰性土壤的能力，等等

Study on the seed setting and kernel characters of F1 derived from the crosses between Triticum aestivum and its related species such as Triticum durum, Triticale and Secale cereale was carried out by the means of artificial emasculation and pollination.

采用人工去雄和授粉的方法研究了普通小麦、硬粒小麦、小黑麦、黑麦间不同杂交组合的结实率及其F1籽粒的形态差异。

About a year after pollination, the generative cell of the four-celled male gametophyte undergoes division, giving rise to two kinds of cells—a sterile cell and a spermatogenous cell.

在授粉后大约一年，四个中生殖细胞-细胞男性的配偶体接受区分，引起细胞的二个类型-一个不毛的细胞和一个 spermatogenous 细胞。

They damage female strobili during the interval between pollination and fertilization .

在传粉与受精的间隔期间，他们毁坏了雌球花。

The receding calculations and experiment analyses in this subject are built on the blood cast of pig tongue.

本研究课题的前期工作是采用猪舌血管铸型模拟人舌而进行的数值计算与实验分析。

"Each human infection constitutes an opportunity for genetic modification of the virus through reassortment, mutation, or both...."

&每一次人类的感染都暗藏着一次基因修改的机会，无论是通过病毒的整合、突变或者兼而有之。。。。&
