Abstract

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, and the fruits were collected manually in matrices located on campus, usingas a selection criterion those who were mature. 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.

Highlights

Queiroz commonly known as sibipiruna, coração-de-negro, sibipira, belonging to the Fabaceae family, is native to the Atlantic Forest, a characteristic Brazilian biome
Considering the shortage of information and the need to detect the phenotypic variability of the species Poincianella pluviosa var. peltophoroides the aim of the study was to biometrically characterize the fruits and seeds, thereby helping in their conservation and improvement
The fruits of Poincianella pluviosa var. peltophoroides were manually collected from two hub trees located 100 meters away from each other, at University of Campina Grande (UFCG) center previously mentioned, and were used as the fruit selection criteria those who were ripe

Summary

Introduction

Peltophoroides (Benth.) L.P. Queiroz commonly known as sibipiruna, coração-de-negro, sibipira, belonging to the Fabaceae family, is native to the Atlantic Forest, a characteristic Brazilian biome. Queiroz commonly known as sibipiruna, coração-de-negro, sibipira, belonging to the Fabaceae family, is native to the Atlantic Forest, a characteristic Brazilian biome It is found throughout Brazil, with a higher incidence rate on the coast of Bahia, Rio de Janeiro and the Pantanal of Mato Grosso. The fruits are dehiscent in a light beige color, like a flattened vegetable, and a diameter about 3 cm. Its size can reach up to 20 meters in height, with a rounded crown of approximately 15 meters in diameter and its orthotropic branches, which grow vertically (HALLÉ et al, 1978; LORENZI, 1992; VIDAL & VIDAL, 1992; ENDRESS, 1994)
