Název v původním jazyce

Mineral nutrition in aquatic carnivorous plants: effect of carnivory, nutrient reutilization and K+ uptake.

Popis výsledku v původním jazyce

Processes of mineral nutrition were studied in the shoots of 5 rootless species of aquatic carnivorous plants. In Aldrovanda vesiculosa and Utricularia australis shoots pre-cultivated with or without prey, NH4+ uptake in both species was around 1 mmol kg-1FW h-1 and was slightly higher in the minus Prey variants. K+ uptake by shoots at 15 μM NH4+ was very low or rather distinctly negative due to an uptake interference with NH4+. K+ uptake in light from a NH4+-free medium was always greatest in the apical (or photosynthetic in U. stygia) shoot segments, and ranged from 0.07-0.61 mmol kg-1FW h-1 in 5 aquatic carnivorous species while it was always the lowest or even negative (in U. vulgaris and U. stygia) in basal or carnivorous shoot segments. A. vesiculosa and U. australis shoots grown at high (83 μM) and very low K+ concentration (2-4 μM) showed relatively efficient N and P reutilization (28-62 %) but very low or negative K reutilization (5.3 to -8.5 %) in senescent shoot segments in both species.
