| Selenium (Se) is an essential micronutrient for humans and animals which is circulated to food chain via crop plants. Agronomic biofortification with Se is used in areas where the soil Se content is low and Se deficiency causes health problems. Brassica species are efficient in accumulation of soil Se and therefore an attractive choice of species for biofortification. Se uptake and translocation was studied in B. rapa and B. napus in field experiments applied with 0, 6 or 20 mg Se ha-1 as Na2SeO4 and foliar sprays of 30 mg Se ha-1 as Na2SeO4 or Na2SeO3. In addition, a HPLC-ICP-MS based method to identify and quantify organic Se-compounds in seeds and meals was developed. High concentration of Se accumulated in seeds (1.89 μg g-1) and after oil... |

| We are investigating the role of legumes as components of bioenergy production. Two separate experiments, one with annual species and other with perennials, were established at Viikki in 2007. Selected grasses, legumes (or nitrogen fertilizer) and additional species were sown singly or in blends of two or three species. |
