Morphological peculiarities productive shoots and pollinators of Astilbe chinensis

The evolution could occur at the agreed upon in plants and their pollinators. Therefore, the structure of the inflorescence and flowers, often tailored to a specific pollinator species. The structure of flowers usually is constant for species of plants, but it varies in Astilbe chinensis. This may be due to the preferences of their pollinators. However, pollinators have not been the study in A. chinensis hitherto. The present study showed that A. chinensis has a wide range of a visitor, who have different preferences over time visiting flowers, different goals and behaviors. Coleoptera and Hymenoptera dominated among the pollinators of A. chinensis. Environmental conditions have a significant impact on the mode of pollinators visiting the flowers. Temperature and the humidity are important for pollinating of A. chinensis. Temperature and humidity limit the frequency visits of Coleoptera more than Himenoptera, they prefer higher temperatures and lower humidity for visits into flowers of A. chinensis. Coleoptera were not specifies as pollinators Astilbe earlier. Research results are cause for revision characteristics of plants, which is pollinating by beetles. A. chinensis produces small flowers with varying structure, collected in thyrsus, forming a significant amount of pollen over a long flowering period. Therefore, a plurality of pollen must be critical after pollination beetles and flower size, apparently irrelevant.
