Abstract

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.
