Unavailability of pineapple planting materials has become one of the main bottlenecks in the exportation of the main pineapple cultivar produced in Benin. To increase the availability of homogenous planting materials, we determined the effects of stem cutting types and buds induction on the propagation of pineapple. Three stem cuttings types and two buds induction regimes were assessed on three cultivars following a split-split-plot design with four replicates. The growth data collected were subjected to analyses of variance followed by Student-Newman-Keuls test. We used the generalized linear models with Poisson distribution to analyze the count data and the generalized mixed effect models to analyze count data repeated in the times. Buds induction regime negatively affected pineapple stem propagation. Cutting types significantly affect propagules number and uniformity in all cultivars. Slice cuttings produced more uniform propagules. We also found a relationship between the propagules weight and height in Smooth Cayenne and Adjago cultivars. These results provide guidance for the production of uniform planting materials in pineapple particularly for Smooth Cayenne and Adjago’s cultivars.
