摘要
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）。
：The freeze injury and recover of Annona species was investigated in the region of Zhanjiang, Guangdong province. The younger trees or tender shoots would have more serious freeze injury and longer recover period. Active growth in winter made the shoots cambia injured first. According to the cold-resistance, 9 species (variety) of 2 genus were divided into 3 groups as follow, resistance: A.cherimola, A.glabra, R,deliciosa; Less-resistance:A.reticulata, A.montana(adult trees),A.atemoya Ho-rt, African Pride(var.); Nonresistance: A.squamosa,A.muricata, A. Montana (seedlings).
