Abstract
This study aimed to characterize the behavior of different cultivars of Vigna unguiculata L. Walp. to osmotic stress, from germination to vigor parameters. The experimental design used was completely randomized in a 14 × 4 factorial arrangement, with fourteen cultivars and four levels of osmotic potential (0, −0.1, −0.2, and −0.4 MPa) of the germination solution. BRS-Novaera and BRS-Pajeú cultivars were characterized with possible tolerance at both the −0.1 and −0.2 MPa levels. The study pointed to the BRS-Pujante cultivar as the most sensitive to the −0.4 MPa level. The multivariate technique used allowed for a satisfactory characterization of the treatments adopted.Keywords
