Abstract

Maianthemum F.H. Wigg. is a genus of perennial plants inhabiting temperate and subtropical regions of Eurasia and North America. Maianthemum sensu stricto includes just a few species that have a wide geographic distribution, are morphologically close, and possess open flowers adapted for a wide range of flower visitors. The present study is aimed at investigating the pollination biology of Maianthemum s.s. A comparison of the pollination biology of these species growing in the same area allows us to clarify ecological differences between the species. Investigation of the pollination biology of the same species in different parts of its range allows for the specification of variation in range of pollinators due to the environmental conditions. We studied pollination of M. bifolium in two far-apart locations (Moscow Region and Primorye Territory); also, in parallel, we studied three species M. bifolium, M. dilatatum, and M. intermedium in the same location in Primorye Territory. Proterandry is typical of all Maianthemum ssp. populations studied here. The studied species have a wide range of flower visitors. All of them can contribute to pollination, but the most stable and effective pollinators of Maianthemum s.s. are bees (Anthophila) and hoverflies (Syrphidae). Geographical position of population is the most important factor defining the range of pollinators of Maianthemum bifolium. The range of pollinators is weakly specific to the three species of Maianthemum s.s.

不同产地菊花(天门冬科)的传粉生物学

菊花。是一个多年生植物属，生长在欧亚大陆和北美洲的温带和亚热带地区。狭义菊(Maianthemum sensu stricto)包括地理分布广泛、形态相近、开放花朵适合多种赏花者的少数种。本研究旨在探讨菊花传粉生物学的研究，通过对生长在同一地区的两种菊传粉生物学的比较，可以澄清两种菊传粉生物学的差异。对同一物种在其分布范围不同地区的传粉生物学进行调查，可以说明传粉媒介的分布范围因环境条件而发生的变化。我们在两个相距遥远的地区(莫斯科地区和滨海地区)研究了双歧杆菌的授粉;同时，我们在滨海边疆区同一地点研究了双歧分枝杆菌、扩张分枝杆菌和中间分枝杆菌3种。菊花是所有菊花的典型品种。这里研究了人口。所研究的物种有各种各样的花访客。它们都有传粉的作用，但最稳定有效的传粉者是蜜蜂和食蚜蝇。种群地理位置是决定两叶菊传粉者分布范围的最重要因素。传粉者的分布范围对三种菊的特异性较弱。

期刊介绍： Botanica Pacifica (BP) publishes peer-reviewed, significant research of interest to a wide audience of plant scientists in all areas of plant biology (structure, function, development, diversity, genetics, evolution, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, fungi, and lichens). BP requires authors to frame their research questions and discuss their results in terms of contemporary problems of plant biology. While the geographic focus of the journal is the Pacific region, research submissions that demonstrate clear linkages with other regions are welcome. BP aims to foster the exchange of research ideas between countries with diverse cultures and languages.
