Reversal of γ-Ray-induced Dormancy of Potato Tubers by Gibberellic Acid

Abstract

POTATOES (var. Up-to-date), which were free from sprouting, were packed in polyvinyl chloride bags and irradiated with 8,000 and 12,000 rads of γ-rays during a ‘shut-down’ period of the swimming-pool-type reactor Apsara. The dose-rate during the period of irradiation was 200 rads/min. Based on a sample of 81 potatoes in each case, the numbers sprouting, 35 days after irradiation, were 81 in control, 9 with a dose of 8,000 rads and none with a dose of 12,000 rads.
