The effect of sucrose concentration in the culture medium on the formation of abscisic acid and the activity of the photosynthetic apparatus of grape plants in vitro

Abstract

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.
