A comparison of photosynthetic and respiration rates in six aquatic carnivorous Utricularia species differing in morphology.

Popis výsledku v původním jazyce

Oxygen-based net photosynthetic (PN) and dark respiration (RD) rates were measured in trap-free leaves of different age of Utricularia australis and U. vulgaris. PN and RD were compared in adult trap-free leaves in three species with linear shoots (U. australis, U. vulgaris, U. purpurea) and four populations of three rhizomatous/rosette species (U. dichotoma, U. resupinata, U. volubilis) under standard conditions (25 oC, 400 ?mol m-2 s-1 PAR, 0.25 mM CO2). In U. australis and U. vulgaris shoots, dry-weight based RD was highest in the youngest segments (174-184 mmol kg-1 h-1). Chlorophyll-based PN rates along the shoots in both species were almost constant. Dry-weight based PNmax in U. australis was significantly greater than that in U. vulgaris (163469vs. 107756 mmol kg-1 h-1), while the CO2 affinity (Km) was opposite: 4810 vs. 212 ?M. The linear-shoot species have higher PN rates than the other subgroup (732-1592 vs. 155-687 mmol kg-1DW h-1).
