Abstract

Increment of levels of both lipoxygenase and superoxide-dismutase which typically increase with age or upon light deprivation is significantly lowered by cytokinin treatment. It is suggested that cytokinin on the one hand by means of inhibition of polyunsaturated fatty acid catabolism prevents incipient formation of free radicals while on the other serves as a scavenger of radicals already formed.
