查询词典 pollination

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.

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.

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
