Cím:Trace element content of several weed seed / Győri Zoltán, Filep Tibor, Lehoczky Éva
Dátum:2014

Megjegyzések:Although there is a potential contamination of cereal grains by weed seeds, an evaluation ofmicroelement and potentially toxic element content of weed seeds concerning the potential contribution to the culture plant grains is still lacking. In our study, 30 seed samples from different weed families were analysed for some potentially toxic elements (Al, Cr, Hg, Pb) and microelements (Fe, Mn, B, Zn, Cu, Ni, Co, Se). Taking consideration the fact that even at low level of weed seed contamination of the cereal grains (1 % m/m)) increased significantly the toxic element concentrations of that, Al and the Sr can be regarded as potentially harmful elements concerning to the food chain. There is a significant increase of Al concentration at 5 % contamination level; the concentration was nearly two-fold comparing to the ingenious concentration, while for Sr the final concentration of the grain+weed seed mixture is higher by 166.7 % than the initial concentration. In case of microelements, the modifying effect of the weed seeds on it was more moderately. There was 1.9-21.2 % increase for Cu, 0.2-47.9 % for Mn and 0.5-7.8 % for Zn

Cím:Variability in macronutrient composition of weed seeds / É. Lehoczky, T. Filep, N. Mazsu, M. Kamuti, Z. Győri
Dátum:2016
ISSN:1589-1623 1785-0037
Megjegyzések:The analysis of the element composition of weed seeds and shoots could provide new data for their biological and ecological assessment. In the present study, seed samples of 30 weed species from different plant families were analysed for macronutrients (K, Ca, Mg, N, P, S) and high variability was found. There was a considerable difference in the N content of weed seeds, with the highest value for Asclepias syriaca and the lowest for Xanthium spinosum. The macroelement ratio also exhibited a wide range of values, e.g. the N to S ratio varied from 0.2 to 14.2. When crop seed data were compared to those of weed seeds from the same family, the K, Ca, Mg, P and S concentrations in weed seeds were found to be significantly higher in many cases. There were significant differences both in the macroelement concentrations and, in some cases, in the nutrient ratios of weed seeds from different plant families. Significant differences were found for K, Mg, P and S, and for the N/S and Ca/P ratios. This was confirmed by PCA, which illustrated not only differences between weed species, but also the fact that weed plants from the same family formed groups.
