The effects of turbulence velocity on Egeria densa Planchon was studied for 12 weeks using mechanically oscillating grid-generated turbulence without mean flow. The root-mean-square of the turbulence velocity fluctuations (u′) ranged from 1.62±0.44 to 2.86±0.8cms −1 (high turbulence), 1.36±0.2 to 1.86±0.78cms −1 (medium turbulence) and 0.67±0.12 to 0.81±0.16cms −1 (low turbulence)...
This experimental study focused on the seasonal changes and mobilization of nutrients between plant parts to understand the implications of self-thinning in the ecology of Zizania latifolia (Griseb.) Turcz. ex Stapf. The observations of shoot density, above- and belowground biomass, and total nitrogen and total phosphorus concentrations were conducted from February 2002 to August 2003. The biomass...
