We examined the relationships between adherence strength to culture net and basal part shape of Neopyropia yezoensis blade “nori”. The range of adherence strength was 0.030 – 0.204 N per blade. Length and width of basal parts, blade length and blade width tended to increase as the values of adherence strength raised. Adherence strength showed strong correlation with width of basal part. Moreover, adherence strength correlated with blade width. It was thought that the values of adherence strength and length and width of basal parts related to decrease water temperature in growing waters. However, it was suggested that a viewpoint of the relationship between adherence strength and width of basal part would be useful.
