The influence of red light on the growth of coleoptiles and mesocotyles of etiolated and pre-irradiated oat seedlings was investigated. Red light (15 min.) applied on whole seedlings stimulated the elongation of coleoptiles and inhibited the growth o

The endogenous content of ABA in the cotyledons of Pharbitis nil is high during the light phase before an inductive 16-h-long dark period. During the night, however, at the beginning, the level of ABA is relatively low with the tendency to increase d
