Abstract

The aim of this work was to detect differences between two species of long pepper by karyotypic analysis. Five acessions of Piper hispidinervum C. DC. (Piperaceae) and Piper aduncum L. (Piperaceae), belonging to germplasm collection of Embrapa Acre, were analysed using squashing technique and Feulgen staining. The chromosome number observed for both species was 2n = 24 and karyotype presented small metacentric chromossomes, with average length of 1.38 mm in P. hispidinervum and 1.32 mm in P. aduncum. Karyotypic descriptions pointed out that the species are not different.
