Abstract— The influence of
uncoupling of oxidative phosphorylation in
mitochondria on surviving of winter wheat seedling during
low-temperature stress was investigated. It was shown that infiltration
of winter wheat seedling by exogenous uncouplers caused the increase of
oxygen consumption, seedling’s temperature and surviving. Vice verse
inhibition of electron transport through the main cytochrome and
alternative pathways decreased surviving of winter wheat seedlings
during cold stress.
