“…Our observations confirm the poor development of the A. ananasoides embryo in ripe fruits, indicating a morphological dormancy. In addition, although the integument can provide physical dormancy (Molina-Guerra et al, 2020), Anastácio and Santana (2010), indicate that the integument of A. ananassoides is permeable and therefore the seeds do not have tegumentary dormancy. Nevertheless, the seed coat may contain chemical inhibitors, such as phenolic compounds that prevent embryonic growth (chemical dormancy) (Bewley et al, 2013).…”

Ananas ananassoides (Baker) L.B.Sm. is a wild pineapple, commonly found in the savannas. This study aimed to describe the morpho-anatomy and histochemistry of its seed. The observations were made in the longitudinal and transverse sections, using an optical microscope. The cell arrangement in the seed coat, ripples in the integument, the ratio of embryo size and endosperm amount, and the number of strata in the aleurone layer are anatomical characteristics that may contribute to distinguishing this species. The starch in the endosperm, lipids and proteins in the embryo, constitute the seed's main nutritional reserves. The homogeneous embryo and phenolic compounds present in the seed coat and in the aleurone layer possibly contribute to the dormancy in this species. This study presents information relevant to the taxonomy and physiology of A. ananassoides, which represents contributions to the global knowledge of this species with a high potential as ornamental.
