Protective role of cytokinin under the heat stress on wheat plants

M.M. Musienko, V.V. Zhuk, L.M. Batsmanova
Abstract

The protective role of cytokinin 6-benzylaminopurine (BAP) on wheat plants was studied under the heat stress conditions. It was shown that treatment of wheat plants by BAP before stress protected leaf photosynthetic apparatus from degradation, stimulated its recovery and increased pigments content. Protective effect of BAP was connected with antioxidant enzymes activity stimulation and endogenous content of reactive oxygen species H2O2 regulation in the wheat mesophyll leaf cells.

Keywords: BAP, hyperthermia, chlorophyll, H2O2, antioxidant enzymes
