【 摘 要 】

The effect of different containers was evaluated to produce cocona seedlings (Solanum sessiliflorum) and jurubeba (Solanum paniculatum). The experiment was performed in the mesoregion of Alto Solimões, in Benjamin Constant, Amazonas state, Brazil, in a particular production area. The seeding was done in black holed polyethylene bags and polystyrene trays with 128, 200 and 288 cells with volumes of 250.00; 32.61; 21.60 and 9.88 cm³, respectively. We adopted a completely randomized design with four containers, four replicates, being assessed five plants per replicate. The seedlings of cocona were evaluated at 27, 38, 45 and 52 days after sowing (DAS) and of jurubeba at 38, 45, 52, 59 and 66 DAS. We evaluated the number of leaves; length of the main root, the aerial and total parts of the plant, fresh and dry matter of the main root, fresh and dry matter of the aerial part. There was no difference on the number of leaves of jurubeba at 45 and 66 DAS; there was no difference on the number of leaves of cocona at 52 DAS; there occurred a greater number of leaves of cocona when seeded on trays containing 200 cells; The other characteristics for both species presented higher values when the seeding was done in the plastic bags, at all evaluation dates.
