摘要： 为了研究嘉宝果在重庆北碚地区引种的气候适应性，对嘉宝果引种后进行了观察，分析了引种源地和北碚地区气候背景，以及嘉宝果引种后物候期的变化情况。结果表明：嘉宝果引种北碚地区后，无死亡现象，生长状况正常，能够适应北碚地区的气候环境。嘉宝果的开花期、成熟期比起原产地推迟1 个月左右，每年的开花、成熟次数减少为2 次，产量减少。嘉宝果物候期与积温、日照有着密切的联系，积温越高、日照条件越好，物候期则偏早，每年第1 次开花时的活动积温在1500℃左右。北碚地区气温偏低、日照偏少是造成嘉宝果引种后物候期发生变化的主要原因。

Abstract: To study the climate adaptability of Myrciaria cauliflora (DC) Berg in Beibei, Chongqing, the authors observed the growth of Myrciaria cauliflora (DC) Berg after the introduction, and analyzed the climate background of the introduction provenance and Beibei, studied the phenological phase changes after the introduction. The results showed that: after being introduced into Beibei, Myrciaria cauliflora (DC) Berg grew normally and was able to adapt to the climatic environment; however, its anthesis and maturity was postponed one month after leaving the provenance; besides, the annual flowering and maturity frequency decreased, and the yield declined; the phenological phase of Myrciaria cauliflora (DC) Berg was closely related to accumulated temperature and sunshine; the higher the accumulated temperature was, the better the sunshine condition would be and the earlier the phenological phase came; Myrciaria cauliflora (DC) Berg would begin to flower when the active accumulated temperature came to around 1500℃. The low temperature and less sunlight in Beibei resulted in phenological phase change of the introducedMyrciaria cauliflora (DC) Berg.
