THE EFFECT OF GAMMA RADIATION ON SPROUT PREVENTION AND ITS PHYSIOLOGICAL MECHANISM IN THE POTATO TUBER AND THE ONION BULB
Potato tubers and onion bulbs were irradiated with gamma rays at 3000, 7000, and 12000-r levels to investigate sprout prevention and physiological mechanisnas. The potatoes were irradiated during the dormant period and at the beginning of the sprouting period. Bud growth on tubers of the 3000-r lot was more vigorous than on the control specimens. Buds on the 12000-r lot were completely suppressed, while some of the 7000-r lot developed buds 3 months late. Sugar content and oxygen uptake increased immediately after irradiation but declined sharply thereafter. The onions were irradiated soon after harvest and at the pre-sprouting period. Their sprouting was completely inhibited even at 3000 r. It was observed that the irradiation did not cause any important alteration on growth promoting and inhibiting substances in the inner bud.
