摘要：

Loring and "Elberta" peaches and "Golden Delicious" apples were irradiated with UV (254nm) to doses of 0.84 X 10(4) to 40 X 10(4) erg/mm2 then stored. "Loring" were stored 10 days and "Elberta" 20 days at 12-degrees-C. "Golden Delicious" were stored 30 days at 20-25-degrees-C in a dark room. Fruit were examined and differences in percentage rot and in physical-chemical properties determined. Percentage rot decreased with increasing UV dose. Fruit were firmer, pH and soluble solids lower and acidity higher for UV-treated than for nontreated peaches; pH was lower and acidity and ascorbic acid higher in UV treated than in nontreated apples. Percentage weight loss was less for UV-treated apples. The results indicated that UV treatment not only reduced storage rots but also delayed ripening of peaches and apples.
