| The in vitro culture of embryos is an important technique to enable the rescue of embryos from incompatible crosses. Studies analyzing the factors that affect the in vitro culture of zygotic embryos are scarce. This study evaluated the effect of the genotype (Capsicum baccatum and C. frutescens), the composition of the culture medium (MS and ½ MS medium with different concentrations of sucrose, IAA and GA3) and the stage of development (globular, cordiform, torpedo and cotyledonary) in the in vitro culture of immature embryos. Embryo germination was influenced primarily by the stage of development of the embryo and the composition of the culture medium. Regardless of the species, the most suitable culture medium for the germination of globular and... |

| ABSTRACT: Essential oils are the most important compounds produced during secondary metabolism in aromatic plants. Essential oils are volatile, have characteristic odor and are used as defensive agents by plants. In pepper, it is possible to say that essential oils are the “flavor fingerprint” of each species. In the present article, eight species of pepper were studied in order to extract their essential oils and oleoresins, test their antibacterial and antifungal activities and also to identify the compounds present in the most bioactive samples. Results demonstrated that two essential oils [Pimenta dioica (L.) Merr. and Schinus terebinthifolius] and three oleoresins (Schinus terebinthifolius and Piper nigrum white and black) recorded significant... |
