Ananas species (Bromeliaceae) are herbaceous monocotyledonous perennial tropical plants. Some of them are grown as ornamental, mainly because of their beautiful, exotic and long-lasting inflorescence and foliage. Some hybrids of Ananas comosus var. bracteatus × A. comosus var. erectifolius are being selected for use as potted plant, landscaping and even as cut flower. The objective of this study was to characterize the development of two ornamental pineapple hybrids as potted plant. Two accessions (‘A’ and ‘D’) of ornamental pineapple from the Pineapple Germplasm Bank of Embrapa Cassava & Tropical Fruits were used. The acclimatization of micropropagated plants lasted 60 days and afterwards plantlets were transferred to 1-L plastic pots containing commercial substrate. Plants were kept under protected environment (50% shading) and were fertilized monthly. Evaluations were made on the morphological plant characteristics (plant height, number of leaves and dry matter content) and response to floral induction. Accession ‘A’ (with predominantly purple-green leaves, green at the leaf base and apex area) had a greater development (higher leaf length, number of leaves and dry matter accumulation) compared to accession ‘D’ which had light green leaves. Accession ‘A’ had also more persistent old leaves and needed pruning. Both accessions were small-sized plants and had no spines on the leaf margins. Slow growth was noticed during the first 90 days of cultivation. The highest need for fertilization was between 90 and 150 days. Plants became responsive to floral induction at 10 months. We concluded that both accessions are suitable for pot cultivation.
