The biological characters of 35 main species whose fresh fruits are edible were studied , including special flavor , size , shape , blooming time and harvesting time. Some of them can be spread in the subtropics as cultivated varieties. The utility of important fruits is briefly intro-duced. The nutrition ingredients of 11 common fruits are analyzed. The thesis points out that the fruit plant resources have to be preserved and protected because of the rainforest degeneration and that study on acclimatization of wild fruits there should be carried out .
