摘要
The morphometric and phytochemical parameters of seeds of three populations of Echium vulgare L were compared. Two metallicolous populations (designated as MZ and MC) originated from waste deposits left over Zn-Pb ore smelting and processing and the reference population originated from an uncontaminated area (NM-nonmetallicolous population). The length, width, weight, and surface area of collected seeds were measured; additionally, the germination ability and vigour index for each population were determined. Moreover, heavy metal, seed oil, and secondary metabolite concentrations were measured. The results obtained indicated differentiation in the seed size and germination ability between the populations. The smaller size of seeds from the metallicolous populations was accompanied by lower germination ability; however, the seeds from the MC population achieved the highest vigour index. Furthermore, the MC population was characterized by the lowest concentration of allantoin and rosmarinic acid; additionally, the seeds of the MC population contained higher content of seed oils and increased contribution of saturated fatty acids and monounsaturated fatty acids by ca. 60 and 45%, respectively, and a decreased (by 16%) fraction of polyunsaturated fatty acids compared with the NM population. The strong differentiation of the MC population coincided with the high seed metal accumulation. (C) 2016 Elsevier Ltd. All rights reserved.
