原始语种摘要: Abstract(#br)The effect of increasing soil Zn concentrations on growth and Zn tissue concentrations of a metal-accumulating aspen clone was examined in a dose–response study. Plants were grown in a soil with a low native Zn content which was spiked with Zn salt solutions and subsequently aged. Plant growth was not affected by NH 4 NO 3 -extractable soil Zn concentrations up to 60 μg Zn g −1 soil, but it was completely inhibited at extractable concentrations above 90 μg Zn g −1 soil. From these data an effective concentration of 68.5 μg extractable Zn g −1 soil was calculated at which plant growth was reduced by 50%. The obtained information on toxicity threshold concentrations, and the relation between plant Zn accumulation and extractable soil Zn concentrations may be used to assess the...
