Two contrasting ecotypes of Phragmites australis adapted to high (Lake Templiner See: Templ) and low (Lake Parsteiner See: Par1) N supply were investigated regarding the leaf content of photosynthetic pigments. Pigment contents were greatest in middle leaves compared to uppermost (still developing) and lowest leaves (already senescent). The highest content was always yielded by chlorophyll a followed...
Two genetically different stands of Phragmites australisdiffering in their trophic status were investigated regarding seasonal changes in shoot morphology, stand structure, standing crop and N-, P-content in the above-ground and below-ground biomass. A model was developed describing internal and external nutrient cycles of two distinct ecotypes – translocation type and assimilation type. In adaptation...
