摘  要：
以长春市建植小叶女贞庭院绿篱为研究材料,观测群体花期、单株花期、单花序与单花花期,收集5月份有关气温数据,分析其对花期性状表现是否构成影响及程度。结果表明:2014—2016年小叶女贞开花时间为6月2日至25日之间,3 a群体花期平均为21.3 d,各年度相差在1 d之内,盛花期为12~13 d;单株开花时间最短植株为16 d,最长者为19 d,平均为17.5 d;单花序为8~12 d,单花为4~5 d。小叶女贞为夏初开花树种,此时气温等气象因子稳定,花期基本不受天气微小变化影响,开花时间亦相对稳定。

摘  要：
The group flowering phase,individual plant flowering phase,simple inflorescence and simple flower flowering phase were observed by taking Ligustrum quihoui courtyard hedgerow of Changchun as materials to analyze whether it affected the flowering phase character expression and the extent by gathering relative air temperature data of May. The result showed that the flowering time of Ligustrum quihoui was June 2nd to 25 th between 2014 to 2016. The average group flowering phase of 3 years was 21. 3 d. The differ of each year was within 1 d. The full-blossom period was 12 ~ 13 d. The flowering time of individual plant was 16 d. The longest was 19 d. The average was 17. 5 d. The simple inflorescence was 8 ~12 d. The single flower was 4 ~ 5 d. Ligustrum quihoui bloomed in early summer when the meteorological factor such as air temperature was stable. The flowering phase was not affected by weather change. The flowering time was also stable.
