SELENIUM IN PORTUGUESE WHEAT GROWN UNDER FOLIAR SUPPLEMENTATION REGIME Ana Sofia Almeida 1 , Benvindo Maçãs 1 , José Coutinho 1 , Catarina Galinha 2 , Maria do Carmo Freitas 3 , Adriano Pacheco 2 1 Instituto Nacional dos Recursos Biológicos (INRB), Estrada de Gil Vaz, Apartado 6, 7351-501 Elvas, Portugal. 2 CERENA-IST, Instituto Superior Técnico, Av.

Keywords: Selenium, Triticum aestivum L., Triticum durum Desf., biofortification Selenium is an essential micronutrient for humans and animals, yet it is deficient in at least one billion people worldwide. Plants and plant-derived products transfer the soil-uptaken selenium to humans; therefore, the cultivation of plants enriched in selenium can be an effective way to improve the selenium status on humankind. This paper focuses on determining the ability of bread and durum wheat to accumulate selenium after supplementation. One of the methods for supplementing this element in plants is foliar application with selenium solutions. These supplemented crops of wheat samples, bread wheat; Triticum aestivum L. (Jordão cultivar) and durum wheat; Triticum durum Desf. (Marialva cultivar), were used to determine if there is an increase of selenium content in cereal grains by comparing them with cereals cultivated in 2009 and harvested in 2010 with no supplementation. The experiments were done in two different growth stages – booting and grain filling – using sodium selenate and sodium selenite at three different selenium concentrations: 4, 20 and 100 g per hectare. Total Se is assessed by cyclic neutron activation analysis (CNAA), through short irradiations on the fast pneumatic system (SIPRA) of the Portuguese Research Reactor (RPI-ITN). Preliminary results show that the experiment was successful, since the selenium concentration increased in the cropped grains and reached values up to 35 and 50 times the non-supplemented crops of Jordão and Marialva, respectively. Supplementation in booting stage seems to be more effective for Jordão cultivar, while for Marialva grain filling stage shows more effectiveness.
ALIMURGIC HERBS AS POTENTIAL SOURCE OF MINERALS IN HUMAN NUTRITION Marianna Bandiera 1* , Maria Clara Zuin 2 , Paola Lucchini 1 , Giuseppe Zanin 1 , Giuliano Mosca 1 , Teofilo Vamerali 3 1 Department of Environmental Agronomy and Crop Science, University of Padova, Italy 2 Institute of Agro-Environmental and Forest Biology, CNR, Italy 3 Department of Environmental Sciences, University of Parma, Italy * Corresponding author: marianna.bandiera@unipd.it Technological progress and food standardisation in the last few decades has narrowed the number of species supporting human diet, causing a loss of genetic resources (spontaneous herbs) and popular knowledge. The use of edible spontaneous species is known as phytoalimurgy. In this study, 18 alimurgic species spontaneously growing in the Veneto region and belonging to 10 different families were screened for their mineral contents. The herbs were grown in silty-loam soil in a phytoalimurgic garden at the experimental farm of the University of Padova (Legnaro) during 2010-2011, and the edible parts (leaves, shoots or roots) were harvested in May 2011. The highest concentrations of 6 nutrients (Ca, Fe, Cu, Mn, B, Li) were found in Borago officinalis L. leaves, Cu and Li being particularly elevated (126 and 2.9 mg kg -1 d.w., respectively). Campanula rapunculus L. provided high concentrations of Co and Mo, but was poor in Ca (5 times lower than in B. officinalis). Within species ranking, sprouts of Humulus lupulus L. were lowest in Fe (83 mg kg -1 d.w., i.e., 13× lower than the maximum), Li and Mo, but richest in P (6,970 mg kg -1 d.w.) and Zn (77.4 mg kg -1 d.w.). P and Mg were markedly concentrated in Silene alba (Miller) Krause. Half of the species belonged to the Asteraceae family and only rarely did they accumulate high levels of nutrients aboveground, probably due to root retention; the few exceptions were Crepis vesicaria L. for Ni (5.5 mg kg -1 d.w.) and Pichris echioides L. for Cr (3.18 mg kg -1 d.w.), both twice as high as the mean for the species. Selenium was not detected in any species, whilst S, Na, P, K, Mo and B had high bioaccumulation factors. These preliminary results show that alimurgic herbs have an interesting natural nutritional value, which may be further investigated and exploited through specific agricultural practices.
