Atemoya propagation must be done asexually; in this context, cutting represents an alternative. This work aimed to verify the most appropriate branch part of atemoya (Annona cherimola Mill. x Annona squamosa L.) cv. 'Gefner' for cutting. The experimental design was completely randomized, in a 3x3 factorial arrangement (plant growth regulators x cutting types), with 5 replicates of 12 cuttings. The plant growth regulators IBA 0.5% and NAA 0.5% were applied as talc in the base of cuttings, besides the control. The different cutting types were taken from three stem regions (apical, medial and basal). The treated cuttings were placed in polystyrene trays containing Plantmax® commercial substrate to allow rooting and taken to an intermittent mist chamber, where they were kept for 136 days. The assessed variables were: percentage of live cuttings; percentage of live cuttings with rooting; percentage of rooted cuttings with remaining leaves, sprouts, and remaining leaves + sprouts; percentage of rooted cuttings without leaves; root number, average length and dry matter mass per rooted cutting; leaf area; and dry matter mass of remaining leaves and sprouts. Atemoya presents higher potential for seedling production using apical cuttings without treatment and medial cuttings treated with NAA (0.5%).
