Résumé

Although vegetative growth was significantly more vigorous in the southernmost site, Echinochloa was able to grow actively even at high latitudes. Conversely, flowering decreased gradually from south to north. Maximum temperature in August was the best predictor of floral emergence. Temperature had an effect on biomass accumulation and allocation as well as on floral emergence. Plants grown in the coolest thermoperiod produced a small number of heavy seeds, whose germinability was superior to that of plants grown in the other temperature treatments. Maternal families represent a significant source of variability for reproductive characteristics. The presence of genetic effects suggests that E. crus-galli has the potential for further evolution with regard to temperature. -from Author
