| Abstract: | Summary A method is described for assessing the activities of growth substances using excised potato buds. Plugs containing an apical bud were excised and the cut surfaces wrapped in vitafilm. The buds were held for up to thirty days at 20°C without rotting. Daily treatment of buds for 5 days after excision, with either gibberellic acid or an extract of potato sprout promoted breaking of dormancy and growth of sprouts. |
