Changes in Mg-Cu-Zn isotopic features in a system red cracking bolete - soil over an extended period

Popis výsledku v původním jazyce

We studied Mg-Cu-Zn isotope systematics of the Xerocomellus chrysenteron mushroom samples collected during two consecutive growing seasons from three sites underlain by granite, amphibolite, and serpentinite bedrock. None of the elements analyzed in mushrooms (Mg, Cu, Zn) displayed site-dependency in concentrations. The studied soils were depleted in 26Mg isotope (delta 26Mg =-0.78 to-0.30%o) and displayed a very wide range of delta 65Cu values (-0.85 to +0.67%o). Values of delta 66Zn were mostly negative for soils from the granite-based site (-0.33 to +0.07%o), positive for soils from the amphibolite-based site (+0.03 to +0.12%o), and only slightly deviated from zero for soils from the serpentinite-based site (-0.09 to +0.09%o). Observed difference in isotope compositions between the mushroom-bearing and mushroom-free soils was most likely due to the presence of mushroom&apos;s mycelium in the mushroom-bearing soils. Isotopes of Mg, Cu, and Zn fractionated to different extent during both uptake and within-mushroom translocation. Mushrooms displayed higher uptake of isotopically light Mg (Delta 26MgFB-soil =-0.71 to-0.12%o), isotopically heavy Zn (Delta 66ZnFB-soil = 0.61-0.91%o), and isotopically variable Cu (Delta 65CuFB-soil =-1.22 to +1.03%o). The ranges of the within-mushroom isotope fractionation were significant: Delta 26Mg displayed a total range of values of 1.09%o; Delta 65Cu, of 0.65%o; and Delta 66Zn, of 0.38%o. No uniform scheme of the within-mushroom isotope fractionation was observed for any studied element.
