Application of "Seamac 600", a cytokinin-rich seaweed concentrate, on roses of CVS. "Mercedes", "Jaguar", and "Gabriella", produced 14%–47% more "bottom breaks". The higher rates of increase were obtained when foliage was comparatively sparse and more light penetrated to the graft area, and the lower rates of increase corresponded to denser foliage and lower light intensities.
