MORPHOLOGY OF FLOWER, FRUIT, SEED, PLANTLET, SEEDLINGS OF Cabralea canjerana (Vell.) Mart.

ABSTRACT

Collections of botanical material from 20 trees of Cabralea canjerana (.Vell) Mart were conducted in the city of Frederico Westphalen, RS. The morphological features of flowers, fruits, seeds, germination, plantlet and seedling were obtained through observations, measurements and illustrations. The inflorescence is paniculate, racemosa with small hermaphrodite flowers. The simple fruit is a septifragal capsule, semifleshy of dark red coloration, late dehiscence. Seeds range from 1 to 10 per fruit, being 1 or 2 together in each subesferical ellipsoid shape locule with thin tegument of brownish coloration, entirely surrounded by aryl orange-red coloration. Internally, the seeds are unalbuminous with axial embryo, invaginate, cotyledons of ovoid shape, fleshy, the hypocotyl-root axis is conic, short and thick. Germination is semi-hypogeal and the seedling phanerocotylar. The length of fruits and seeds was variable, and the fruits ranging from 2 to 2,9 cm long, 2,2 to 3,1 cm wide and 2,2 to 3 cm thick, while the seeds ranged from 0,7 to 0,8 cm, from 0,63 to 0,75 cm and 0,5 to 0,6cm, respectively. Four months after germination, seedlings, already formed, had an mean of 18 cm height and stem diameter of about 3 mm. Through morphological characteristics, it is possible, along with the illustrations, the identification of the species in its natural environment, as well as assistance in laboratory analyzis.
