Regulation of the investment in carnivory in three aquatic Utricularia species: CO2 or prey availability?

Popis výsledku v původním jazyce

he structural investment in carnivory (IIC) as a relative proportion of trap biomass (DW) was investigated in three aquatic Utricularia species (U. vulgaris, U. australis, U. reflexa) in a 12-14 d greenhouse growth experiment. The two-factorial experiment included the presence or absence of prey (zooplankton) for a high (0.30-0.58 mM) or low (0.024-0.062 mM) CO2 concentration in the culture water. Various plant growth parameters, including traps and foliar N and P contents in young shoot segments, wereestimated. Generally, under a surplus CO2 and favourable light conditions, the trap production as the IIC in aquatic Utricularia is supported by prey capture more (positive feedback) than the apical shoot growth, but the IIC apparently does not depend onthe very low shoot N or P content. At medium CO2 concentration, shoot N and P contents are very variable and regulate the IIC by negative feedback (?nutrient regulation). Under poor photosynthetic conditions, however, the trap production
