Desenvolvimento de sementes de Poincianella pyramidalis (TUL.) L.P. Queiroz. durante o processo de maturação fisiológica.

Abstract

Biometrics fruit and seeds provides information for the maintenance and operation of the species, variability between individuals in a given area and allows comparisons of the same species occurring in different geographic locations. Thus aimed to characterize biometrically fruits of P. pyramidalis (Tul.) LP Queiroz during physiological maturation process in riparian areas of Caatinga. The field research was conducted in the Umburanas Creek, New Farm, rural municipality of Sumé - PB. The laboratory phase was conducted in Ecology and Botany Laboratory (CDSA / UFCG). The crops began at 15 days after anthesis (DAA) and extended to 150 DAA, being evaluated the following parameters: weight, length and diameter of the fruit. According to the data obtained it was found that the physiological maturity of the seeds took place 150 days after anthesis, since after this point were the maximum values of emergence and vigor.
