Species arboreal, native of the Atlantic Forest biome, Poincianella pluviosa var. peltophoroides (Benth.) L.P. Queirozis widely used in urban landscaping due to the beauty of its flowering and indicated for the recovery of degradedareas as an initial or pioneer secondary species. The objective of the study was to characterize the fruits and seedsbiometrically, thus helping in its conservation and improvement. The work was conducted at the Federal Universityof Campina Grande, campus of Patos-PB,

To obtain the biometric data, the fruits were selected and separated100 fruits and 100 seeds at random. To measure the biometric variables (length, width and thickness) of the fruitsand seeds, a digital caliper with a precision of 0.1 mm was used and then the amplitude of the classes of each analyzedvariable was calculated. The results showed that the fruits presented variation in the length of 4.51 to 10.53 cm,however, the predominance of fruit frequency was in the class of 6.03-6.77 cm. The seed length varied from 0.918 to1.208 cm, with a higher incidence in the class of 1.064-1.112 cm, where it concentrated about 45% of the seeds. It isconcluded that the fruits Poincianella pluviosa var. peltophoroides presented greater uniformity in the variable lengthand their seeds presented greater uniformity in the biometric variables in which they were evaluated, being this afavorable criterion for its propagation.
