| Abstract: | Summary In potato (Solanum tuberosum L., cv. Sebago), benzyladenine (BA) promoted tuberization at high day/night temperatures (32°/18°C), while gibberrellic acid
(GA) and chlorethylphosphonic acid (CEPA) reduced tuberization at low day/night temperatures (22°/18°C). These results are
consistent with the hypothesis that temperature exerts its influence on tuber formation by altering the balance between endogenous
gibberellins, cytokinins and inhibitors, but not ethylene. |
