Estudo Taxonômico de Plântulas de Espécies' Arbóreas que Ocorrem no Parque do Museu Paraense Emílio Goeldi (Belém - Pará). Bignoniaceae: Tabebuia serratifolia Vahl (Nichols.)

Abstract

Tabebuia serratifolia Vahl (Nichols), known as ípê amarelo, is a tree that is approximately 8-20 meters tall, very common in the Amazon region. It is an ornamental species, and is widely used in landscaping in general. We used 30 fruits, 30 seeds and 10 seedlings, describing their morphology. The fruits' general morphology, color, texture, consistency, dehiscence and indumentation were recorded; the tegument, endosperm and embryo of the seeds were described, as well as the main vegetative elements of the seedlings. The seedling was considered to be the stage of development where the eophilia were fully formed. The entire study was based on specialized literature and the morphological characters were illustrated with photographs. The species presented a capsule-type fruit; dehiscent; calyx absent; anemochoric dispersal syndrome. Winged seeds; bilobed; brownish forehead, pearly and shiny; hilum in depression, cartilaginous, brownish; cotyledonary embryo, axial, foliaceous, ínvaginous, pleurorrizo and cotyledonary, axial, foliaceous, ínvaginous; large cotyledons, green, bilobed, fleshy and auriculate with exposed radicle, presenting radicle with margins hidden by the base of cotyledons. Phanerocotyledonary epiphytic germination. Seedling with green, simple, opposite, symmetrical, ovoid, serrate eophylls, with green gland-like structures, rounded, and peninérvea encrustation, craspedodroma, The characterization of the morphology of fruits, seeds, germination and seedlings is very important for the identification of the species in the field, in the early stages of development, and consequently provides subsidies for forest management.
