Assessment of Habitats Area and Nickel Hyperaccumulator Plant Alyssum Genus in Albania

Developed soils on serpentine rocks occupies a large area in Albania which contains huge reserves of, nickel, chromium and cobalt. The purpose of our study was to identify the species, the habitats of metal’s hyperaccumulator Alyssum genus in Albania and to analyze the metals content in soils and plants too. There are accomplished several field trips investigated the mine, ultramafic and mafic soil in different areas of Albania. The soil samples and plants are taken randomly in each habitat for chemicals analyzes and species identifications. The sample of Alyssum sp. was identified according to the Flora Europea.Alyssum muralewasrepresented by three different varieties. Alyssum murale; var. chlorocarpumwas was represented in 11 habitats in south and southeast Albania. Alyssum muralevar. chalcidicum was identified in three habitats and Alyssum murale var. subvirescens also was identified in two habitats. Alyssum markgrafiiwas represented only in one habitat in North Albania. Soil and plant samples were analyzed for total Ca, Co, Cr, Mg and Ni. Based on results, each site exhibited a high concentration of one or more metals. The nickel content in soils varied between 1050 and 5650 mg kg-1dry matter. The soils pH values varied from 6.12 to 8.12. The nickel content in plant of Alyssum murale varies from 6900 to 18300 mgkg-1 dry matter. The nickel content in plants of Alyssum markgrafii is from 13770 to 22640 mg kg-1 dry matter. These results confirmed that hyperaccumulatorAlysum sp. is developed as one endemic plant on Albanian serpentine soils. Alyssum muraleis represented in four location and 16 habitats by three different varieties. Alyssum markgrafii is represented only in one isolated habitat in North Albania.
