title: [Regulation of flowering plants of different biotypes].
abstract: The patterns of control of flowering are analyzed in plants of different biotypes. The photoperiodic reaction of flowering taken as an example, the whole net of control is considered: from the environmental stimulus through its physiological transformation in the leaf in the corresponding hormonal impulse which, in turn, controls the realization of genetic programme and formation of generative organs in the stem buds. The photoperiodically neutral plants taken as an example, the patterns of age control of flowering are considered. In plants of different photoperiodic groups the synthesis of complementary components of florigen was shown to proceed either autonomously under the photoperiodic effect or under the inducing effect of definite photoperiods. The autonomous and inducible mechanisms of biosynthesis of the flowering hormones have a common base, the genetic system to which the environment sends its stimuli through the hormonal interactions. The interaction of hormonal and genetic developmental factors is considered, the evocation of flowering in the stem buds taken as an example.
