There was a continuous cold weather in Sihui city, Guangdong province, which caused a cold disaster to Syzygium samarangense planted locally during December 2016 to February 2017 and December 2017 to February 2018. In this paper, based on the cold disaster of S. samarangense planted locally as the basis of cold disaster, according to the cold disaster grade, the differences of cold resistance of each variety were compared, and the cold damage investigations were carried out on three kinds of S. samarangense varieties of "Black Pearl", "Big leaf red" and "Indonesia Big Fruit". The results showed that all three varieties were affected by different degrees of cold disaster, and the cold resistance ability was "Big leaf red" "Indonesia Big Fruit" "Black Pearl". The chilling ability of the young trees cultivated by the "black pearl" layered seedlings is better than that of the saplings cultivated by the grafted seedlings. According to the survey results, "Big leaf red" can be used to promote planting in favorable areas in Sihui city.
