Sucrose: Plants in in vitro culture conditions need an exogenous carbohydrate source because most of the plants grown in vitro tend to shift from autotroph to heterotroph. Selecting the best carbohydrate source and concentration in culture media depends on the plant species and the micropropagation phase.
