Growth and reproduction of Rumex maritimus and Chenopodium rubrum under different waterlogging regimes

摘要: SUMMARY The influence of different waterlogging treatments on above-ground development and subsequent flowering seed production Chenopodium rubrum L. Rumex maritimus was studied in a greenhouse experiment. C. rubrum, typical occupant low sandy beaches at times when floods have subsided, appeared to be suppressed by all regimes. R. maritimus, an inhabitor wet mud flats old river beds, found quite tolerant conditions; early waterlogging, during the rosette stage, led increase dry weight some cases. In general, changed more than biomass as result waterlogging; responses greatly depend Intermittent generally caused damage did continuous especially case C. rubrum. Even produced less seeds under conditions intermittent waterlogging. The results demonstrate that adaptations to, from, flooding regimes which vary substantially field situation.
