Abstract EN
This study investigates the relative importance of leaf carnivory on Nepenthes alata by studying the effect of different nitrogen (N) sources on its photosynthesis and N metabolism in the greenhouse.
Plants were given either inorganic NO3-, organic N derived from meal worms, Tenebrio molitor, or both NO3- and organic N for a period of four weeks.
Leaf lamina (defined as leaves) had significant higher photosynthetic pigments and light saturation for photosynthesis compared to that of modified leaves (defined as pitchers).
Maximal light saturated photosynthetic rates (Pmax) were higher in leaves than in pitchers.
Leaves also had a higher light utilization than that of pitchers.
Both leaves and pitchers of plants that were supplied with both inorganic NO3- and organic prey N had a similar photosynthetic capacity and N metabolism compared to plants that were given only inorganic NO3-.
However, adding organic prey N to the pitchers enhanced both photosynthetic capacity and N metabolism when plants were grown under NO3- deprivation condition.
These findings suggest that organic prey N is essential for N.
alata to achieve higher photosynthetic capacity and N metabolism only when plants are subjected to an environment where inorganic N is scarce.
