Název v původním jazyce

Root nutrient uptake enhances photosynthetic assimilation in prey-deprived carnivorous pitcher plant Nepenthes talangensis

Popis výsledku v původním jazyce

Carnivorous plants grow in nutrient-poor habitats and obtain substantial amount of nitrogen from prey. Specialization toward carnivory may decrease the ability to utilize soil-derived sources of nutrients in some species. However, no such information exists for pitcher plants of the genus Nepenthes, nor the effect of nutrient uptake via the roots on photosynthesis in carnivorous plants is known. The principal aim of present study was to investigate, whether improved soil nutrient status increases photosynthetic efficiency in prey-deprived pitcher plant Nepenthes talangensis. Gas exchange and chlorophyll (Chl) fluorescence were measured simultaneously and were correlated with Chl and nitrogen concentration as well as with stable carbon isotope abundance(delta C-13) in control and fertilized N. talangensis plants. Net photosynthetic rate (P (N)) and maximum- (F-v/F-m) and effective quantum yield of photosystem II (I broken vertical bar(PSII)) were greater in the plants supplied with nut
