An increase in sucrose in the medium increased the content of pigments, gene expression of the photosynthetic apparatus, growth processes, and H2O2, but decreased the quantum yield of photosynthesis. With a change in the sucrose content in the medium, the expression of ABA1 increased most intensively. 30 g/l of sucrose in the medium inhibited the expression of genes involved in the formation of ABA.
