Chenopodium album mainly occurred in roadsides, crop fields, wastelands, and near animal farms. We found that C. album produces two kinds of seeds those are black and brown type. The freshly mature brown seeds were non-dormant for the whole year. In contrast, there was considerable variation in the dormancy of the black seeds. The brown seeds germinated faster and seed germination rate was higher than the black seeds. An optimum temperature was 20/10℃ to 25/15℃ (day/night) for the germination of both type seeds. Germination rate of brown seeds was higher than the black seeds under various NaCl concentrations. At the 320 mM salinities, 10% of brown seeds germinated while the germination was not observed in the black seeds. The total seed protein content was much lower in the black seeds than in the brown seeds suggested that more energy might be available for radicle to break the seed coat in the brown seeds. The seeds full emerged at 0.5 cm and no emergence was seen beyond 4 cm burial depth. The results obtained from our study will be useful to maximize the efficiency of management tactics in the C. album infested area in Korea.
