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.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
英文摘要: 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 fr...
