By which mechanism does prey capture enhance plant growth in aquatic carnivorous plants: Stimulation of shoot apex?
Original language description
Dark respiration (RD) and tissue N and P content were estimated in young parts of shoot apices in three aquatic carnivorous plants, Aldrovanda vesiculosa, Utricularia australis, and U. bremii, grown with or without prey in a 12-d greenhouse growth experiment. The apical shoot growth rate of fed plants in all three species was significantly higher by 49-85 % than that of the unfed variants and so also was shoot branching. In A. vesiculosa only, tissue N content in apices and shoot segments of fed plantswas significantly greater that in unfed plants. Both apical and shoot P content was significantly greater in fed plants of A. vesiculosa and U. australis, while the P contents were the same in U. bremii. Feeding on prey significantly increased RD of shoot apices only in A. vesiculosa. In conclusion, the more rapid growth due to feeding could hypothetically be caused by stimulating the cell division in the youngest parts of shoot apex due to a faster allocation of prey-derived N and P.
