Goodyera repens l. r. br. in the polessy state reserve ukrainian ssr ussr

, : Goodyera repens l. r. br. in the polessy state reserve ukrainian ssr ussr. Ukrayins'kyi Botanichnyi Zhurnal 46(6): 42-45

The state of two cenopopulations of Goodyera repens L. R. Br. in the Polessye State Reserve has been studied depending on ecological environmental factors. The age structure of cenopopulations, dynamics of their quantity in time have been investigated. Under optimal ecological and phytocenotic conditions (the molinia-bilberry-green moss pine forest) the G. repens cenopopulation is characterized by stability of age parameters and quantity and does not depend on drift of diaspores from outside and on changes in ecological factors. It is attributed to a young, normal-type population. Under extreme conditions (the lichen pine forest) the G. repens population is rather unstable. Its age parameters and quantity sharply vary depending on the ecological environmental factors. The population analysis has permitted attributing that population to the regressive one. The self-support of the G. repens population under reserve conditions occurs due to the vegetative renewal. Perculiarities of the G. repens phenology are studied.
