Abstract
Seasonal changes in the growth rate of duckweeds—Lemna minor L. andL. gibba L. associated in the communityLemnetum gibbae (W. Koch 1954)Miyawaki etTx. 1960—were investigated at the Podzámecký fishpond at Průhonice near Praha, during the growing season of 1969. Initial and final dry weight values (W 1 andW 2) of selected samples of the duckweed community were assessed at weekly intervals. The relative growth rate (RGR) was calculated from the dry weight increments, and correlated with water temperature, mean air temperature and sunshine duration. A linear regression equation was fitted to describe the dependence ofRGR on these factors.
