Mean turion content of N in all species was 1.87 % DW, P 0.26 %, K 0.65 %, Ca 0.15 %, and of Mg 0.19 % DW. Of all nutrients, only turion K content differed significantly between carnivorous and non-carnivorous species (0.48 ± 0.03 vs. 1.04 ± 0.10 % DW). For all plant species and sites (n = 18), turion nutrient content did not depend on nutrient concentrations in the ambient water at the time of turion initiation. In conclusion, turions of aquatic plants also represent storage organs for mineral nutrients (N, P) though their storage function is presumably less distinct than that for carbohydrates.
