- Abstract
In this paper, methods for the application of radiotracers in the Cobra Lily ( Darlingtonia californica), a carnivorous pitcher plant, are described. The uptake of radiotracers such as 42K and 54Mn into the pitcher trap in aqueous solution could be proven, whereas uptake of 59Fe ions could not be observed. No-carrier-added 54Mn was taken up by the plants, regardless of extremely low concentrations. In contrast to earlier experiments using 14C and 15N-based tracers, the methodology presented allows quick, simple and reliable quantification of the nutrient uptake. The results of our experiments lead to a deeper biological understanding concerning the trace element household of this carnivorous plant and the absorption of micro-and macronutrients from trapped prey.
