| 以 2016 年 12 月—2017 年 2 月和 2017 年 12 月—2018 年 2 月间的低温对种植在四会市的莲雾
（Syzygium samarangense）造成的寒害为调查基础，根据寒害等级标准，比较了 3 个品种的（“黑珍珠”、
“大叶红”和“印尼大果）抗寒性差异。结果表明，3 个莲雾品种均受到不同程度的寒害，抗寒能力大小
依次为“大叶红”＞“印尼大果”＞“黑珍珠”。同时对“黑珍珠”不同来源苗木进行寒害比较，说明采
用高枝压条培育的苗木比嫁接培育的苗木具有更好的抗寒性。调查结果认为“大叶红”嫁接苗和“黑珍
珠”高枝压条苗可在四会市选择有利地域推广种植. |

| Abstract: |
| 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 |
