摘　　要：对黑樱桃种子处理方法进行研究的结果表明,生理后熟和抑制物质的存在是造成黑樱桃种子休眠的主要原因,暖温层积90天后再冷温层积120天可以有效打破种子的休眠,其中暖温层积是种胚后期发育的主要时期,而冷温层积是消除抑制物抑制作用的关键。After experimenting on the treatment methods of Cerasus maximowiczii seeds, it is believed that physiological ripening and the existence of inhibitors are the main reasons for the dormancy of C. maximowiczii seeds. The dormancy of C.maximowiczii seeds can be effectively broken by warm-temperature stratification 90 days later and cold-temperature stratification 120 days later. Warm-temperature stratification is the main period of late embryonic development, and cold-temperature stratification is the key to eliminate the inhibition of inhibitors.
