Abstract The Dahlia (Dahlia coccinea Cav.) is a plant that has been cultivated and genetically improved due to its ornamental importance; anyhow, its radical system accumulates reserve carbohydrates in the form of inulin and other fructans. Inulin is considered a part of the dietetic fiber from vegetable food sources, and it is also considered as a prebiotic compound. Inulin is extracted mainly from chicory and artichoke through different separation methods being Dahlia’s tubers an interesting option for industrial utilization. The aims of this study were to (1) propose a simple extraction method of inulin from Dahlia’s tubers, and (2) evaluate the… More >

Abstract A. americana L. is a crop with very little genetic variability. In order to evaluate the effect of ethyl methanesulfonate (EMS) to induce variability in in vitro plantlets of A. americana, different explants (meristems, leaves and roots) were evaluated for the production of callus. MS medium supplemented with ANA (2.68 μM) and BAP (2.68 μM) was used. Callus obtained from apical meristem were treated with 15 mM EMS for two hours after which shoot formation was induced using 2,4-D (0.11 μM) and BAP (44 μM). The EMS induced variations in the morphometric and morphological parameters of the plantlets obtained, with… More >
