Abstract
The changes of the total RNA occurring during germination in potato tubers have been investigated. During germination the development of the new sprouts is accompanied by a progressive decrease of RNA. A preferential breakdown of high molecular weight RNA has been observed. Tubers deprived of the buds mantain the level of RNA of the quiescent tuber. Gibberellic acid treatment promotes the development of the sprouts, but is ineffective in inducing changes in the RNA level when supplied to isolated explants of potato tuber both germinating or deprived of buds.
