摘　　要：通过两年的研究，认为果桑的花芽分化可分为未分化期，花序原基分化始期，花序总轴分化期，单花原基分化期，萼片分化期，雌蕊分化期及柱头子房形成期等７个阶段。其分化期为５月下旬至ｌｌ月中旬，盛期在７～９月份，并观察分析了其分化特点。The two-year study has revealed that the stage of differentiation of flower bud inwhite mulberry, Morus alba, comprises seven substages, i.e.,nondifferentiation substage, dif- ferentiation substage of rachis primordium, rachis differentiation substage, differentiation sub-stage of individual floral primordia,sepal differentiation substage, pistil differentiation substage, and substage of ovary and stigma formation. The entire stage of bud differentiation lasts from lateMay to mid November, and the climax comes in July through September. The respective charac-teristics of differentiation are also described.
