摘　　要：为确定牡丹品种花期在秦皇岛地区的物候情况,对引种至该地区的1个野生种以及29个牡丹品种的花期进行了物候观察。结果表明:1)引进牡丹在3月上旬进入萌芽期,4月上旬进入展叶期,4月中旬进入风铃期,4月中下旬进入露色期,4月下旬到5月上旬进入始花期,4月下旬至5月下旬进入末花期9月中下旬进入枯黄期;2)30个引进牡丹种质资源,以始花期为判断标准,可分为早、中、晚等3类,其中野生卵叶牡丹花期最早,‘京玉天成’‘岛锦’‘旭港’‘海黄’花期晚;而根据开花持续时间,可分为超短、短、中等和长等4类,其中‘映红’开花持续时间最长可达到17 d,‘京玉天成’‘岛锦’和‘花王’开花持续时间最短,仅有7 d,最早和最晚开花之间相差20 d。The florescence of 30 tree peonies(including 1 wild variety and 29 cultivars)introduced into Qinhuangdao area is observed to provide reference for the rational arrangement of peony cultivation and management.The results show that 1)the introduced peonies enter the budding stage in early March,the leaf-spreading stage in early April,the wind-bell stage in mid-April,the dew-colored stage in mid-late April,beginning of florescence in late April to early May,final florescence in late April to late May,and the yellowing stage in mid-late September;2)the 30 introduced peony germplasm resources can be divided into early,middle and late florescence according to the distribution of the waiting area of the flowering stage,among which the wild oval-leaved peony is the earliest to enter florescence,followed by‘Jingyu Tiancheng’‘Daojin’‘Xugang’and‘Haihuang’.The flowering durations are quite different,‘Yinghong’is the longest with 17 days,‘Jingyu Ttiancheng’‘Daojin’and‘Huawang’are the shortest with only 7 days,and the flowering duration differs by 20 days between the earliest and the latest.
