The phenological growth stages of various species of monocotyledonous and dicotyledonous plants can be uniformly coded using the Biologische Bundesanstalt, Bundessortenamt, und Chemische Industrie (BBCH) scale. The aim of the present study was to determine the duration of different phenological stages and the temperature requirements of the sugar-apple, Annona squamosa, during two crop cycles in the semiarid region of Brazil. Phenological stages were divided into eight of ten possible principal stages: (0) bud development, (1) leaf development, (3) shoot/branch development, (5) inflorescence emergence, (6) flowering, (7) fruit development, (8) fruit maturity and (9) senescence and the beginning of dormancy. The phenological cycle of the sugar-apple from having closed leaf buds to the fruit ripening stage lasted 149 and 164 days with temperature requirements of 1684.5 and 1786.7 degree days (DD) for the first and second crop cycles, respectively. The results provided important information that will inform the correct timing for crop management practices.
单子叶和双子叶植物的各个物候生长阶段可以使用德国联邦生物研究所、联邦品种局和化学工业协会（BBCH）标准进行统一编码。本研究的目的是确定在巴西半干旱地区的两个作物周期内，番荔枝（Annona squamosa）不同物候阶段的持续时间和温度需求。物候阶段分为十个可能的主要阶段中的八个：（0）芽发育，（1）叶发育，（3）茎/枝发育，（5）花序出现，（6）开花，（7）果实发育，（8）果实成熟以及（9）衰老和休眠开始。从封闭叶芽到果实成熟阶段，番荔枝的物候周期在第一个和第二个作物周期分别持续149天和164天，温度需求分别为1684.5度日（DD）和1786.7度日（DD）。这些结果提供了重要信息，将为作物管理实践的正确时机提供参考。
