Abstract

Abstract The addition of dimethyl sulfoxide (DMSO) to a colchicine solution applied to germinating black raspberry seed increased the percentage of induced polyploids more than did colchicine alone. Concentrations of DMSO higher than 2% were phytotoxic to germinating seeds when combined with colchicine. DMSO had no discernible effect on penetration of colchicine to the apical dome in blackberry shoot apices. There was evidence of synergistic effect of the chemicals on phytotoxicity of apical tissue.
