The effect of SO2 on sucrose efflux from source leaves of poplar
Dendrobiology 2000, vol. 45: 61-64
Abstract:The present study was aimed at the determining the influence of various concentrations of sulphite (0.5-2.5 mol m-3) on the regulation of sucrose efflux from leaf discs of poplar (Populus deltoides). Sucrose efflux was enhanced by sulphite at a concentration of ≥ 1.0 mol m-3 for the first 60 min of treatment. However, after longer period under sulphite treatment both an attenuation of the stimulation of sucrose release and a reduction of efflux were observed.
