Effect of Lighting Conditions on the Reproductive Success of Cypripedium calceolus L. (Orchidaceae, Liliopsida)

The influence of lighting conditions on the reproductive characteristics of the Cypripedium calceolus L. was studied on the territory of the Komi Republic, where the species is located on the Northern border of its habitat. The study was carried out in the southern part of the region (within the Vychegda-Mezen plain) in 2017. Eight coenopopulations of the species in areas with various light intensities were examined, among which three coenopopulations were in swamps, and five were in forests with varying degrees of the canopy closeness.
