| Résumé : |
"This study was conducted to investigate the distribution and seed biology of Erodium cicutarium in Chungnam province of Korea. E. cicutarium normally occurred in pastures, roadsides, and crop fields. During a whole year after harvest, E. cicutarium seed germination increased with increasing storage time. No germination was found until 60 days after harvest, and began to germinate 90 days after harvest and got reaching full germination 300 days after harvest. The optimum germination temperature was 20℃ and soaking in the sulfuric acid for 20 minutes was the most suitable method to break seed dormancy. Germination of E. cicutarium seeds was decreased by increasing NaCl concentrations. Up to 10 mM of NaCl did not affect E. cicutarium seed germination and less than 20% of seeds germinated at 160 mM of NaCl. Approximately, 78% of seeds emerged at 0.5-2 cm of sowing depth but the seeds did not emerge at a burial depth greater than 4 cm. These results will be useful to develop integrated exotic weed management in the E. cicutarium infested area in Korea." (source : auteurs) |
