| Abstract: | tttttPurposetttttOur aim was to study the relationship between the changes of cell inclusions and flower buds dormancy during the winter.tttttttttttttMethodtttttDormancy status and the changes of cell inclusions were analyzed and compared in flower buds of Prunus persica L. var. densa Makino cv. Zhonghuashoutao at eight different periods during the winter dormancy.ttttttttttttttttttResultstttttThe results indicated that SOD activity gradually increased during the period of endodormancy, and decreased with endodormancy release. POD activity increased at first and then decreased in the stage of endodormancy, and firstly descended and then increased in the progress of endodormancy release. CAT activity gradually decreased and Vc content appeared several large fluctuations in the process of endodormancy maintenance and release. The variation tendency of H2O2 content and ttttttttttttt
