Résumé
Translocation of assimilates in Echinochloa crus-galli from Quebec and Mississippi, and of Eleusine indica from Mississippi was monitored, before and after night chilling. Plants were grown at 28o/22oC under either 350 or 675 mu l.l-1 CO2. Low night temperature reduced translocation mainly by increasing turn-over times of the export pool. E. crus-galli from Mississippi were the most susceptible to chilling; translocation was completely inhibited by exposure for 1 night to 7o at 350 mu l.l-1 CO2. Plants from Quebec were the most tolerant to chilling-stress. Growth under CO2 enrichment resulted in higher 11C activity in the leaf phloem. High CO2 concentrations also seemed to buffer the transport system against chilling injuries.-from Author
