In the spring, aerobic dark respiration (RD) and photosynthetic rates (PN) were measured as criteria of metabolic activity and photosynthetic capacity in dormant turions of 7 temperate aquatic plant species. These rates were also measured in old, original turion segments and in the newly formed shoots of sprouting turions. Two non-carnivorous rooting species (Caldesia parnassifolia, Hydrocharis morsus-ranae) and 5 carnivorous rootless species (Aldrovanda vesiculosa, Utricularia vulgaris, U. australis, U. stygia, U. bremii) were studied. RD values of dormant turions per unit fresh weight (range 1.1-5.4 mmol kg-1FW h-1) were significantly lower (1.9-13 times) for all species, except A. vesiculosa, than those for old segments of sprouting turions (range 5.2-14 mmol kg-1FW h-1). Turions of aquatic plants also function as important storage organs for mineral nutrients (N, P, S and Mg) to ensure the growth of new organs.
