Features of the biology of Goodyera repens (Orchidaceae) in southern taiga pine fores of the Kirov region

The article discusses the biological features of Goodyera repens (L.) R. Br. (Orchidaceae) in pine phytocenoses of the Kirov region. It was established that the studied cenopopulations of Goodyera repens are confined to lingonberry-green moss, blueberry-green moss-sphagnum and lichen-lingonberry-green moss pine forests. In the ecological-cenotic spectra of the studied communities with Goodyera repens, 6 ecological-cenotic groups were identified. The most widely represented are boreal and pine forest species. Goodyera repens is characterized as a shade-tolerant plant, found in moderately moist to humid, acidic to moderately acidic, and extremely poor to nitrogen-poor soil conditions. It has been established that the left-sided type of the ontogenetic spectrum predominates. According to the “delta-omega” classification, the analyzed coenopopulations are represented by a young and maturing type; according to the classification based on the replacement index, they are represented by a promising type.
