Polen de Commelinaceae y Pontederiaceae (Commelinales) humedales rioplatenses (Argentina). Se estudiaron los caracteres granos polen que crecen en áreas rioplatenses. Los estudios se realizaron con microscopio óptico electrónico barrido. actualizaron conocimientos previos sobre elementos esos grupos, describió por primera vez el Pontederia rotundifolia Tradescantia cerinthoides. ambas familias ...

The aim of the study was to evaluate the antioxidant and free radical scavenging properties and to determine the phenolic content of the ethanol extract from five Mentha species [M. longifolia (L.) Huds., M. piperita L., M. pulegium L., M. rotundifolia (L.) Huds., and M. spicata L.]. The antioxidant activities of the extracts were investigated with two different methods, 2,2’-diphenyl-1-picrylh...

The agro-silvopastoral system ‘montado’ is mostly dominated by Mediterranean evergreen oaks such as, cork oak (Quercus suber L.) and holm oak (Quercus rotundifolia). The ‘montado’ production system management aims the maintenance of a balanced sustainable land use to cope with the Mediterranean climate variability. One important issue in cork oak forests is the control shrub growth in order to ...

species. Similar findings have previously been reported for M. piperita (Bricout & Paupardin, 1975) and M. rotundifolia (Bricout et al., 1978). Many of the calluses accumulate only the early precursors of the monoterpenes (namely geraniol, linalol and lavandulol), but some species give rise to cultures that accumulate monoterpenes characteristic of the intact plant. For example, cell lines from...
