摘　　要：在福州国家森林公园对福建山樱花6个品系（ FZ1、FZ5、FZ22、FZ41、FZ67、FZ159）的开花物候特性进行观测，结果表明：福建山樱花的花色主要有深红、粉红和白色3种，开花特性则主要有先花后叶、花叶齐放2种类型；不同福建山樱花品系的开花物候不同，FZ1、FZ5、FZ22、FZ41、FZ67这5个品系在开花持续时间、盛花持续时间方面差异不大，分别为12～14 d、7～9 d，FZ159的开花持续时间为20 d，盛花持续时间为15 d；同一品系的福建山樱花，不同树冠层和不同方位的花枝开花物候不一致，总体表现为在同一树冠层面，西方位的枝条开花最早，北方位的次之，南方位的再次，东方位的枝条开花最迟；在同一方位，下层花枝开花较上层早1～3d；同一品系的福建山樱花花枝开花数量差异不显著，而不同品系的福建山樱花花枝开花数量差异极显著，其中以FZ1花量最大。可为福建山樱花的花期预报、花期调控、园林绿化配置造景提供参考。The test of Cerasus campanulata flowering phenology had been carried out on 6 strains（FZ1,FZ5,FZ22,FZ41,FZ67, FZ159） in Fuzhou National Forest Park.It turns out that this species has 3 flower colour type trains,crimson,pink and white.They bloom before leaf or in the middle of leaf.The different strain has different flowering phenology character.The length of flower season and peak flowering endurance are both quite similar among the 5 strains of FZ1,FZ5,FZ22,FZ41 and FZ67.The length of flower season is 12-14 d,and the peak flowering endurance is 7-9 d.The FZ159 strain flowering last 20 d,with a peak flowering endur-ance of 15 d.All the strains share the same law that they first flower on westward twigs ,then northward ones ,then the southward ,and then comes the eastward.On each specific orientation ,the substratum twigs bloom 1-3 d early then the superstratum ones.There is no significant difference on flower quantity among the same strain Cerasus campanulata individuals,but vrey significant among the different strains trees ,the FZ1 strain have the highest flow number.The research results can provide a foundation for flowering fore-cast,blooming control and landscaping designing.
