Abstract
This study examined the decomposition of blades and culms of aquatic emergent plant species,Zizania latifolia, Phragmites comunis and Typha angustata, The experiment was carried out from July to December, 205 in fresh water of Lake Paldang using litter bag method. The liter bags had 1.2 mm mesh size and were suspended at 1 m depth of water surface. Remaining mas of blades and culms of each species after 97 days was 21.2% and 22.6% of initial mas in Z. latifolia, 32.5% and 56.4% in P. comunis and 44.7% and 38.1% in T. angustata, respectively. The plant tisue having high N concentration and low C/N exhibited the faster decay rate than the others. rate. Water temperature was the most effective environmental factor on the emergent macrophyte liter decomposition in aquatic ecosystems. According to the water temperature, DO, NO3--N, and total phosphate concentration were changed in the linear way. The mas loss of plant tissue of emergent macrophytes showed positive relationship with P concentration in water. The experiments on the decomposition of the liter using diferent mesh sized liter bag did not show significant diferences betwen them. The results suggest lentic and lower part of a stream, was afected by microbial activities better than the micro-invertebrates such as shredders.
