Pineapple production is mostly constrained by unavailability of high-performance suckers. However, somatic embryogenesis (SE) have been revealed the most rapid and controllable method for Pineapple propagation than conventional sucker production methods. The aim of this study was to evaluate the responses of two cultivars of pineapple regenerated through somatic embryogenesis. Thus, calli were induced from crown leaf and plantlets leaf of Smooth Cayenne and Sugar Loaf cultivars. Murashige and Skoog base medium supplemented with vitamins B5 and different in hormonal combinations: Auxins / Cytokins. BAP and / or 2,4-D have been added to base medium for calli maturation and BAP and GA3 for plant regeneration. The results indicated a significant influence of type of explant and copper on callus induction in pineaple cultivars. Likewise, The medium MS with growth regulator combination NAA (0.5 mg/l) + BAP (1mg / l (BAP) has a highly significant influence with 8.8 mature somatic embryos. Also, the growth regulator combinations and the cultivars have significantly influenced somatic embryos regeneration with a high rate of 55.25% shoots by using the hormonal combination BAP (3 mg/l) + GA3 (2 mg/l) for the smooth Cayenne. The protocol developed is a key study for successful mass propagation of the pineapple and genetics transformation of pineapple.
