摘要

The results of studies conducted in Romanovskii district of Saratov region during the period of mass flowering of Orchis militaris L. and Dactylorhiza incarnate (L.) Soo (June 2-16, 2017) are presented. Descriptions of the habitats of the species (a hollow and a pasture), differing in the projective cover and dominants, are given. Elytrigia repens (L.) Nevski, Carex vulpina L., and Potentilla anserina L. dominated in the hollow; Elytrigia repens (L.) Nevski, Festuca pratensis Huds., and Festuca valesiaca Gaudin dominated in the pasture. The ontogenetic structure of populations of these species is shown. In the hollow, juvenile individuals of O. militaris were absent, while immature (23.1%), verginyl (34.0%), and generative individuals (42.9%) were found. In the pasture, juvenile and immature individuals of O. militaris accounted for 6.8 and 9.3%, respectively, and verginyl (36.8%) and generative individuals (47.1%) prevailed. The age spectra of both populations are of the right-sided type. In the age spectrum of the D. incarnata cenopopulation, the proportion of age groups of the pregenerative and generative periods was 52.9%. The high recovery and efficiency indices indicate a steady status of cenopopulations of O. militaris and D. incarnate. Annual monitoring is necessary for assessing the status of the cenopopulations and forecasting their development.

Militaris的幼年个体，而未成熟（23.1％），verginyl（34.0％）和生成个体（42.9％）。在牧场，少年和未成熟的人的O. MILITARIS分别占6.8％和9.3％，而Verginyl（36.8％）和生成的个体（47.1％）占有平。两种群体的年龄谱都是右侧类型。在D. Incarnata enenopopulation的年龄谱中，孕产阶级和生成期的年龄组比例为52.9％。高回收和效率指数表明O. MILITARIS和D. incarnate的en enpopopulations的稳定状态。年度监测是评估临床公开的状态并预测其发展的必要条件。
