Abstract
Poinsettias (Euphorbia pulcherrima Willd. cvs. Annette Hegg Supreme, V-10, and Brilliant Annette Hegg) were grown on heated benches and exposed to root zone temperatures between 18° and 29° C. Increasing media temperatures affected bract size and development, internode length, fresh and dry weight of stems, leaves, and bracts, as well as the number of axillary shoots of cultivars differentially. In general, plants grown at higher temperatures were shorter, had more prominent axillary shoots, and developed anthocyanin sooner than unheated controls.
