Seeds of Rosaceae fruit trees have special dormancy characteristics,and are difficult to germinate under normal conditions,which brings great inconvenience to breeding varieties with excellent quality by hy-bridization.In this paper,the characteristics of seed structure,physiological dormancy and seed coat factors limiting seed germination in Rosaceae fruit trees were systematically reviewed.The research progress of impro-ving seed germination rate of different subfamilies by chemical treatment was especially introduced.The pur-pose of this study was to reveal the commonness and difference in exploring seed germination technologies in Rosaceae fruit trees,and to provide clues for further developing efficient seed germination technologies.
