Biometria e morfologia de frutos, sementes e plântulas de Senegalia bahiensis (Benth.) Seigler & Ebinger

Abstract

The objective of this work was to study morphological characteristics and biometric of fruit, seeds and plantule of Senegalia bahiensis (bramble-white). Fruits were collected in October 2014, on a farm located in the zone rural municipality of Castro Alves - BA. In the fruit of were observed the characteristics: kind; color; length (with and without tip); width (position: distal, medial and proximal); texture and number of seeds per fruit. For the seeds were observed: color, dimensions (length, width and thickness), shape, hilo, chalaza, tegument , embryo e pleurogram. The characteristics for the observed seedlings were: root, hypocotyl, cotyledons, epicotyl and eliófilos. The fruit of Senegalia bahiensis is the legume type, polispémico, dehiscent by two longitudinal slits, that open to let out the seeds. Dry pericarp, epicarp colored brown light the brown dark, there occurrence of greenish brown fruits, having the apex to fruit from shape acuminate. The seed has ellipsoid shape, color dark brown the black, smooth and hard surface. The plantule complete their training at nineteen days after germination, and this is epigeal phanerocotylar. Biometric date of fruit, where the fruits have medium length 8,38 cm, medium length without tip 7,93 cm, average width at the distal position 10,41mm, median position, 12,92 mm, and next, 10,96mm. The seeds have an average length tip 5,40 mm. Work on the morphology and biometrics Senegalia bahiensis species are not found in the literature, requiring a larger number of data and information on the species. This fact proves to be relevant, given the fact the absence of studies on it.
