Abstract
Fatty acid compositions of subcellular membrane lipids were investigated in irradiated potato tubers. In membrane fractions rich in plasmalemma, tonoplast, mitochondoria and endoplasmic reticulum, the percentages of linolenic acid slightly decreased immediately after irradiation at 0.5 kGy. After 10 day storage, the percentages of linolenic acid increased in all the membrane fractions.
