Effects of different concentrations of retardant chlormequat chloride on hypocotyl and first internode lengths of common buckwheat (Fagopyrum esculentum Moench.) were investigated. It was established that treatment of buckwheat plants with chlormequat chloride before presowing led to: reduction of stem length, activation of early and intensive lignification of vascular and mechanical elements, increasing number and size of vascular bundles in correlation with functional reconstructions on donor-acceptor connections of plant organs.
