| Calla (Zantedeschia aethiopica (L.) Spreng.) is a flower that is conquering international markets. It is very important to maintain the healthiness of the crop during its development in order to obtain high quality plants that meet the demands of the markets. The objective of this investigation was to determine the etiological agent(s) of a pathology never observed before in Chile that causes vascular wilt during the cultivation of colored calla developed under greenhouse conditions. Fungal isolates were collected from infected plants. Pathogenicity tests, microscopic observations, and scanning electronic microscopy evaluations were also conducted. Healthy calla tubers were inoculated with isolates of the genus Fusarium Link. Plants grown during 5 months... |

| It is possible to incorporate a lot of natural antioxidants into the human organism by consuming berries which can prevent diseases generated by the action of free radicals. Antioxidants neutralize free radicals and thus protect the organism from the oxidative damage of lipids, proteins, and nucleic acids. Berries stand out as one of the richest sources of antioxidant phytonutrients among various fruits and vegetables. The objective of this research was to determine antioxidant capacity (AC), total anthocyanins (TA), and total phenols (TP) of wild and cultivated berries in different localities of La Araucanía and Los Ríos Regions in Chile. These parameters were analyzed by using the free radical 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH) method,... |
