Correlation between the measured rate of root growth and the predicted rate of root growth calculated based on the cell cycle duration reported in the literature (determined by the 3H-thymidine method). The rate of root growth was calculated using eqn (3). (А) Primary roots of monocotyledonous species. (B) Primary roots of dicotyledonous species. (C) Adventitious roots of monocotyledonous species. Correlation coefficients r = 0.94 (A, B) and 0.95 (C).
