Description
  • The efficiency of N, P and K reutilization in old traps and trap-free shoot segments in the submerged aquatic carnivorous plant Utricularia reflexa and the leaves of non-carnivorous Ceratophyllum submersum was compared with that in the leaves of five terrestrial Utricularia species. In U. reflexa shoots, the mean corrected reutilization efficiency for N was 19% in traps and 37% in leaf nodes and for P was 67% in traps and 52% in leaf nodes. However, the greatest K content both in traps and leaf nodes was found in the old organs and the K reutilization efficiency in both types of organs was negative. In Ceratophyllum leaves, the corrected N, P and K reutilization efficiencies were similar to U. reflexa leaves. In five terrestrial Utricularia species, the following corrected reutilization efficiencies were found: 35-82% for N, 56-84% for P, and 48-91% for K. Thus, reutilization of K in leafy shoots generally occurs only in terrestrial and not in aquatic plants.
