Cím:	Similarities in the Allocation of Metallic Elements in Dietary Plants / Szabó György, Czellér Krisztina
Dátum:	2012
Megjegyzések:	The accumulation of metals in different plant parts may show species-specific patterns, possiblyinfluenced by soil properties. The carrot (Daucus carota) and zucchini (Cucurbita pepo var. giromontia)were studied in five sampling areas with different soils in Hungary. We wanted to know how the differentsoil types affected the uptake and the allocation of the examined heavy metals within the plants. Theaccumulation and allocation of Co, Cu, Fe, Mn, Ni and Zn have been assessed within these agriculturalplants. We found inconsistency between allocation pattern of the plants and the metal content of the soils.We tried to reveal which among the total heavy metal contents of the soils and the attributes (pH, CaCO3-content, humus-content, granulometric composition) plays the most important role in the heavy metaluptake and those allocation within the plants. We found that the allocation of these elements in the selecteddietary plants showed species-specific response. The two studied vegetables have their own allocationpattern, but both accumulate more elements in the leaves, than in the edible parts. We supposed that theexamined plants would give different physiological answers in the cases of soils with different attributes.The Cu and Ni showed low variation within the plant, while Co and Zn had particular variation among thesamples. The Fe and Mn patterns may be influenced by the different soils. In this study we revealed that thesimilarities found in the response of the plants bear functional character, thus they are tending to avoid thehigh accumulation of metals in the reservoirs/propagules regardless their species-specific purposes.
