Specifics of hypericum maculatum restitution after harvesting

H. maculatum biological and restitutional features were studied in Smolensk Oblast, Russian SFSR, USSR, during 5 vegetative seasons (1978-1982). H. maculatum was preserved in phytocenosis due to the fact that the population was able to move towards favorable conditions. Presumably, the population's migration in the experiment was determined, for the most part, by the competition of approaching gramineous plants and the negative effect of H. maculatum harvesting on the vital condition of the population. Harvesting H. maculatum epigeal parts intensively exhausted the population. Repeated harvesting is possible with a 1-yr interval between every 2 yr of harvesting. The level of extractives in the raw material obtained during annual harvesting decreased to the lowest permissible limit.
