Abstract
Hook opening and leaf expansion, measured 24 h after standard red light illumination, were considered as parameters determining the photoactivity of etiolated Phaseolus vulgaris L. seedlings. The experiment was repeated every h during one 17-h period each month for 1 year. The mean values for each experimental period indicated that the photoactivity of the etiolated seedlings changed markedly throughout the year according to a seasonal pattern.
