National audienceThe influence of translocations towards sinks on photosynthetic carbon distribution between foliar starch and sucrose was studied in soybean plants (Glycine max L Merr), cv Kingsoy. After foliar 14CO2 incorporation in situ, the radiocarbon distribution between starch and sucrose and the 14C translocation towards sinks were investigated during the hours following incorporation (fig 1). When the export rate increased or was stimulated by fertilising irrigations, less radiocarbon was incorporated into starch (fig 2). If the translocation decreased, more radiocarbon was used for starch synthesis and the leaf accumulated starch and sucrose (table II). Experiments on source/sink modifications corroborated these data (fig 3). Nutr...
