The dynamics of cytokine content and the total protein and nonprotein forms of nitrogen in tissues of wintering organs of clary sage Salvia sclarea L. and cinquefoil Potentilla alba L. in abnormally cold (2005-2006 years) and abnormally warm (2006-2007 years) winters in Moscow have been studied. A direct correlation between the content of total cytokines and the total and protein nitrogen forms in tissues of wintering leaves and buds has been determined. A correlation link between the level of single cytokines and the protein nitrogen forms has been found.
