In vitro germination of Ibervillea sonorae (S. Watson) Greene

Abstract

The wereque (Ibervillea sonorae) is a climbing plant used in traditional medicine for its antioxidant, antiproliferative, antimicrobial and hypoglycemic properties; the objective of the research was to determine the in vitro germination capacity of I. sonorae. The experimental design was based on pregermination treatments (with and without mechanical scarification with doses of 1.0, 2.0, 3.0 and 4.0 mgL^-1 of AG³ in WPM culture medium and two control samples), the data were analyzed with ANOVA and comparison of means with Tukey-Kramer (P<0.05). The results showed a germination of 56.67 to 61.67%; obtaining 97.29% of normal seedlings with an average height of 50.55 mm and root length of 53.78 mm through mechanical scarification, imbibition and addition of AG³; with a survival rate of 75% at 20 days after transplantation. 2.71% of the total germinated seeds belong to abnormal seedlings, and 38.33% are non-germinated seeds. Therefore, I. sonorae seeds require mechanical scarification and imbibition to allow germination. The germination rate was below 65% indicating that pre-germination treatments should be used for propagation and increase of this species in its wild habitat.
