调查记载了山东省果树研究所枣品种圃 (泰安 )近 80个品种的主要物候期。观察到不同品种发芽期相差 1 3天 ,展叶期、花期相差 5～ 6天 ,成熟期则相差 50～ 60天。果实成熟期早晚取决于品种遗传特性 ,与发芽、展叶、开花期早晚无关。此观察结果可作为引种依据 The survey recorded the main phenophase of nearly 80 varieties of jujube cultivars (Tai’an) in Shandong Fruit Research Institute. Differences in the germination of different varieties observed 13 days, leaf stage, flowering difference of 5 to 6 days, a difference of 50 to 60 days maturity. Fruit maturity depends on the genetic characteristics of early maturity, and germination, leaf exhibition, flowering sooner or later nothing to do. This observation can be used as a basis for introduction
