Light intensity increases the susceptibility of Vallisneria natans to snail herbivory
Institution:Laboratory of Aquatic Plants, College of Life Sciences, Wuhan University, Wuhan 430072, PR China
Abstract:Palatability to snail herbivory (Radix swinhoei H. Adams) and C/N ratios were assessed for Vallisneria natans (Lour.) Hara, in three different experimental light regimes (midday fluxes respectively 280 μmol m−2 s−1, 15 μmol m−2 s−1, and a variable intensity between these two). Higher light intensity as well as prolonged photoperiods increased palatability and growth, and improved C/N ratio by decreasing N content. Snail growth was slightly increased but juvenile survivorship decreased under higher light. The results suggest that the availability of light may affects intraspecific variation in palatability of V. natans.
