Abstract

Hypocotyls and roots of Chenopodium rubrum were tested as possible receptors of photoperiodic signals inducing flowering. The hypocotyl was found to be responsive to such a signal. Its role as the locus of synthesis and/or the transport system of a florigenic stimulus is discussed. The roots respond to light/dark conditions solely by changing their growth rate but they do not seem to be involved in induction of flowering.

Key words

Flowering - photoperiodism - receptory organs
