The effect of the transport of sucrose from leaves of higher plants on the width of the spectra of induction of delayed luminescence was studied. It was shown that the duration of the induction period decreases when the sucrose outflow from the leaves is limited by cooling the leaf petiole for two hours under light. It was concluded that the accumulation of sucrose in the conducting tissues of the leaf stimulates the increase in the CO2 fixation rate on rellumination after dark adaptation.
