调查了广东湛江地区2个属9个种（品种）番荔枝的冻害表现及冻后恢复情况。树龄小、枝条嫩的树体冻害严重，来春生长恢复慢。冬季仍处于活动状态是枝条形成层首先受冻害的内在原因。从抗寒角度把番荔枝分为三类，抗寒类群：秘鲁番荔枝，圆滑番荔枝，比丽巴番荔枝；较抗寒类群：牛心番荔枝，山刺番荔枝（成龄），杂交番荔枝，非洲骄傲；不抗寒类群：普通番荔枝，刺番荔枝，山刺番荔枝（幼树）。
Investigations were made on the frostbite performance and the recovery after the freezing in the two species of nine species (varieties) in Zhanjiang, Guangdong Province. Tree age is small, branches of the tender tree severe damage to spring growth slow recovery. The still active winter is the underlying cause of the first damage to shoot formation. From the point of view of cold resistance are divided into two types of sugar apple litchi, cold-resistant groups: Peru litchi, smooth sugar litchi, Bilibaba litchi; more cold groups: beef heart litchi, litchi litchi (mature) Sugar apples, proud of Africa; non-cold resistant groups: common annona, thorn litchi, mountain thorns litchi (young trees).
