Abstract
In this study, we designed simple method to evaluate of soil seed banks for vegetation management in fallow fields. Soil seed bank of eleven fallow paddy fields, which were various in period and management forms, in hilly and mountainous areas was sampled in summer, 2002. The paper provides effective method to predict succession stage of fallow period by referring to seed banks. We designed screening test system applied Washitani (1987) , which is method of gradually increasing temperature. We showed germination rate more than 80% of last germination rate mainly on paddy weed by this method. Therefore, this was confirmed that a convenient method was effective for grasp of seed bank. However, similarity was low between seed banks and vegetation, it needs that more improvement of the evaluation system made reflect succession stage.
