Abstract
Abstract Cut flowers of rose ( Rosa hybrida L. cv. Samantha) exhibited a longer vase life when opened in solutions containing cobaltous ion (Co 2+ ). The extended vase life in response to Co 2+ was related to 1) an increased water uptake into the cut flower, 2) an improved water balance during opening, 3) a delay in loss of fresh weight, and 4) a prevention of the occurrence of bent-neck. A concentration of 1.5 m m Co 2+ gave maximum beneficial effects without injury to the cut flower, while a 2.0 m m concentration induced some toxic symptoms on leaves.
