Abstract
The effect of ionizing radiation on the change in the composition of the free lipid fraction of various plant species, such as bean, pea, and barley, was studied. The results show an appreciable increase in the lipid peroxide content in the leaves of the shoots irradiated with relatively low doses (1000 r). Chnnges in the composition of unsaturated fatty acids of the free lipid fraction were found within the first hours following exposure to ionizinng radiation. Linoleic, oleic, and other unsaturated acids diasappear completely from this fraction. Oxidation of plant lipids is caused by the in vivo effect of enzymes since no such increase in lipid peroxides has been noted upon irradiation of the substrates of lipid metabolism (such as linoleic acid, carotene, and lipoxidase), and of leaves in which lipoxidase has been inactivated by steam.
