Description

Recently, amenity of human being by plants have been called "green amenity". The authors have been making a series of studies on "green amenity". In the present study, physiological and psychological effects of ornamental foliage plants, flowers(roses) and fragrance on human being were analyzed by means of brain waves (ratio of alpha wave to beta wave) and semantic differential technique. The results are as follows. Higher ratio of alpha wave to beta wave was observed in the case of the presence of fragrance. It is considered that presence of fragrance affects physiological aspect of human being. On the other hand, the presence of roses brought about higher score of factor analysis. It is considered that presence of flowers affects psychological aspect of human being.
