Última A new variety of Bacopa monnieri obtained by in vitro polyploidization Electron. J. Biotechnol. Salvio Escandón,Alejandro; Hagiwara,Juan Carlos; Alderete,Liliana Marisol. The commercial value of Bacopa monnieri, a widespread herbaceous plant in Argentina, can be substantially improved increasing its flower size by chromosome doubling with colchicine. MS supplemented with 0.25 mg/L of 6-benzylaminopurine proved to be an appropriate medium for the in vitro multiplication of nodal segments of B. monnieri. Polyploidization was achieved submerging nodal segments during 24 or 48 hrs in colchicine solution 0.001 and 0.01% P/V, in 1% DMSO. Segments submerged in water and in DMSO 1% aqueous solution were used as controls. DNA contents from recovered plants was measured and characterized and their phenotype described. Two tetraploid plants originated from independent events were detected. These plants showed significant differences...

J. Biotechnol. Escandón,Alejandro S; Miyajima,Ikuo; Alderete,Marisol; Hagiwara,Juan Carlos; Facciuto,Gabriela; Mata,Diego; Soto,Silvina M. The genus Scoparia is native from Argentina. The diversity of colours and shape of their flowers bestows this genus a very interesting ornamental potential. The purpose of the present study is to explore the Scoparia species germplasm by means of in vitro polyploidization in order to improve their ornamental qualities. Accessions of S. montevidiensis var. montevidiensis, S. montevidiensis var. glandulifera, S. nudicaulis, S. hasleriana and S. dulcis were collected and maintained under greenhouse conditions. The Murashige-Skoog medium, supplemented with 0.25 mg/L BAP was used for the nodal segments multiplication of the five Scoparia species. Except for S. hasleriana, the multiplication rate of the other species ranged between 10 and 12 shoots per explant....
