Abstract

Abstract Population-based studies of endangered plant species are key methods for assessment of the status for these plants at any territory. Plant species of the Orchidaceae family are sensitive components in natural ecosystems. That is why determination of the status for their populations can be considered as indicators for the status of natural ecosystem position as a whole. Investigations of three Orchidaceae species populations (Orchis militaris L., Epipactis palustris (L.) Crantz, Malaxis monophyllos (L.) Swartz) were carried out in Central Russia (Republic of Mordovia). Abundance, density, structure and dynamics of populations of these species were studied. Species composition of accompanying flora was established for each rare species. Some morphometrical parameters of individuals for the studied species were measured. Features of ontogenetic spectrum for Orchis militaris and Epipactis palustris populations were shown.

Mordovia共和国(俄罗斯中部)军兰科植物、palustris Epipactis和Malaxis monophyllos种群
基于种群的濒危植物物种研究是评估各地区濒危植物现状的重要方法。兰科植物是自然生态系统中的敏感成分。这就是为什么确定它们的种群状况可以被视为整个自然生态系统状况的指标。兰科3个种群(Orchis militaris L.、Epipactis palustris (L.))的调查克兰茨(L.)在俄罗斯中部(莫尔多维亚共和国)进行。对这些物种的种群丰度、密度、结构和动态进行了研究。确定了各稀有种的伴生植物区系组成。对所研究种的一些形态参数进行了测量。揭示了军国兰(Orchis militaris)和palustris (Epipactis palustris)种群的个体发生谱特征。
