| Abstract/Contents: | (1)Soil solutions were extracted by centrifugation from eleven soil samples from a toxic serpentine soil at Meikle Kilrannoch in Scotland. Analyese showed high concentrations of Mg2+ and NO-3, low ones of Ca2+ and potentially toxic concentration of Ni2+. (2)Nutrient solutions, with composition based on these analyses were prepared. In them were grown two clones of Festuca rubra; one from the Meikle Kilrannoch serpentine and the other from a non-serpentine acid brown earth. Four experiments with different combinations of Ca2+ and micronutrient concentrations were made. In each the effects of different concentrations of Mg2+ and Ni2+ on plant growth were measured. (3)The greatest growth of the Meikle Kilrannoch clone of Festuca rubra was in the water culture with concentrations most similar to soil solutions from the same site. The acid-soil clone plants grew very slowly in this solution. They grew fastest in solutions containing higher concentrations of micronutrients and lower ones of Mg2+, Ni2+, and Ca2+. (4)High Mg2+ concentration appeared to be the main cause of the slow growth of the acid-soil clone in Meikle Kilrannoch soils. However, Ni2+ was shown to be toxic also. (5)Both Mg2+ and Ni2+ toxiocity were amelioration by a higher concentration of Ca2+ and to some extent of micronutrients. The amelioration was associated with a reduction in tissue concentration of nearly all the elements analysed and may involve some restoration of membrane function. |
