摘要

This paper gives the results of the physiological investigations on germination of the Japanese barnyard millet as a weed in rice field. The germination of this weed is irregular, slow and extend over long period. Some seed of the plant have germinated on 8th day after flowering. Afterripening of it will be completed in about 45-days. In normal storage of it, that is, natural drying and storage in desicator, ability of the germination was manitained for 2-3years. But hulled seed will quickly lose this ability in 2-3months. The greater specific gravity of the seeds increased the percentage of germination. Solutions of salts which were used in this experiments did not control the germination, expect K2CrO4 and K2Cr2O7. This seeds have not distinctively both light-germination or dark gemination habit. The optimum temperature of germination is from 30°C to 40°C and 10°C is too low for germination of the plant. Inconstant temperature was dffective as well as the seeds of other weeds. Germination of unhulled seeds was accelerated by sulphauric acid, physical and hulling treatments. Soil-coverings of 0.5 and 1cm have no dffect on the germination of the seeds, 3 and 5cm distinctly but those of over 7cm completely prohibited the germination of the seeds.
