Abstract

Euphorbia pulcherrima Willd. ex. Klotzsch 'Eckespoint C-1 Red' (C-1) a restricted-branching cultivar and 'CB' a free-branching vegetative or grafthybrid, were homo and heterografted. Length and number of axillary shoot nodes of C-1 receiver plants (plants which may receive the branching agent from the donor plants) were partially increased by CB donors with leaves removed and with apical and basal parts removed. Shading of CB donors partially increased the length of axillary shoots and the number of axillary shoot nodes of C-1 receivers above node 4. Production and movement of the branching agent may occur in and go from both stems and leaves of CB poinsettia donors to C-1 poinsettia receivers. Shading CB donor leaves and stems did not prevent the production and movement of the branching agent to C-1 receivers.
