An influence of different sucrose concentrations in the culture media on the photosynthetic parameters, photosynthetic apparatus related genes expression, oxidative processes and acclimation of grape plants cultured in vitro was examined in this article. An increase of the sucrose concentration in the culture media resulted in a reduced expression of several photosynthetic genes. The most effective functioning of the photosynthetic apparatus was discovered by a decreased amount of surcose in culture media. An increase of the sucrose concentration in the culture media disrupts pigments synthesis, particularly carotenoids, which can be a cause of the secondary oxidative stress formation and grape plants growth reduction during acclimation.
