Abstract: Data of the comparative investigation of the viral infection (TMV) and nitrogen starvation in the ratio of chlorophyll a/b, photochemical activity of PS I and PS II, pigment-protein structure of chloroplasts thylakoids and parameters of the fluorescence induction of tobacco leaves are presented. The changes of the structural and functional characteristics of the photosynthetic apparatus testify to negative influence of this factors on the function of both photosystems with primary inhibition of PS II.
