Study on the Adaptability of Different Varieties of Myrciaria cauliflora Berg in the Mountainous Area of Northeast of Guangdong
[Objective]In order to further promote the development of Myrciaria cauliflora Berg industry in the mountainous areas of northeast-ern Guangdong and revitalize the rural economy. Saba,Aurora macula Saba,Fukuoka,Sijihongfei,Ginkgo seed,Argentina,Aiska and Ken-buka eight varieties of Myrciaria cauliflora Berg were introduced to Meizhou,Guangdong,and their growth was observed. [Method]Random-ized block design,eight Myrciaria cauliflora Berg varieties were observed and compared in Meizhou planting base of Guangdong Province since April 2020.[Result]During a whole growth cycle,the results showed that Kenbuka failed to overwinter safely,and the survival rate of intro-duction was 0; the introduction survival rate of Sijihongfei was 60％; the survival rate of the three varieties of Aurora macula Saba,Ginkgo seed and Aiska was 100％,but the growth was poor and the freezing injury was serious; the survival rate of Saba,Fukuoka and Argentina was 100％,and the traits were excellent and the growth potential was good. And the growth of the eight Myrciaria cauliflora Berg varieties showed an obviously positive correlation with temperature and precipitation. The growth of eight varieties of Myrciaria cauliflora Berg was slowly from October to February every year. Varieties with poor low temperature resistance would suffer from different degrees of freezing injury.[Conclu-sion] Saba,Fukuoka and Argentina are suitable for planting in the mountainous areas of northeastern Guangdong.
