以山桃稠李为材料，观测群体花期和单株花期，结果表明：在2013年春季的气象条件下，长春市街路旁栽植的山桃稠李的群体花期时间为15 d，株间变动于8～13 d之间，平均花期时间为10．6 d；株间盛花期时间变动于4～8 d之间，平均为5．4 d。柳河县兰山林场和蛟河市爱林林场野生群体的花期分别为19 d和21 d。相同地点株间花期差异是遗传因素所致；不同地点群体花期差异是环境因素造成的。
以山桃稠李為材料，觀測群體花期和單株花期，結果錶明：在2013年春季的氣象條件下，長春市街路徬栽植的山桃稠李的群體花期時間為15 d，株間變動于8～13 d之間，平均花期時間為10．6 d；株間盛花期時間變動于4～8 d之間，平均為5．4 d。柳河縣蘭山林場和蛟河市愛林林場野生群體的花期分彆為19 d和21 d。相同地點株間花期差異是遺傳因素所緻；不同地點群體花期差異是環境因素造成的。

The florescence of groups and single trees of Padus maackii (Rupr.) Kom was observed.The results demonstra-ted that in the meteorological condition of spring in 2013, the florescence of groups of Padus maackii (Rupr.) Kom which were planted in Changchun street was 15 days.The single tress change was between 8 days and 13 days.The average flo-rescence time was 10.6 days.Furthermore, the full-blossom period change of single tress was between 4 days and 8 days. The average was 5.4 days.The florescence of wild population of Lanshan forestry centre of Liuhe county and Ailin forestry centre of Jiaohe city were 19 days and 21 days, respectively.Consequently, the florescence of single tress difference of the same place resulted from genetic factor while the florescence of groups difference of the different places resulted from envi -ronmental factor .
