title: Flower formation in the short-day plant Kalanchoë by grafting with a long-day and a short-long-day Echeveria.
abstract: Flower formation was induced in the shortday plant Kalanchoë blossfeldiana Poellnitz under long-day conditions by grafting with flowering shoots of the short-long-day plant Echeveria harmsii (Rose) MacBr. and of the long-day plant Echeveria 'pulvoliver' (E. pulvinata Rose x E. harmsii). Vegetative shoots from induced Echeveria plants failed to cause a flowering response in Kalanchoë. The presence of flowering and vegetative shoots side by side on induced Echeveria plants provides evidence for physiological chimeras in this genus.
