Genomic DNA of young reed leaves was subjected to PCR-based random amplified polymorphic DNA (RAPD) technique using random primers. Banding patterns from RAPD showed three major clusters. Group I showing vigorous growth was composed of plants from recently emerging reed patches on the coast shore and was established after the 2000s. Group II formed by reed patches was established at around the 1990s and showed non-vigorous growth along with typical symptoms of reed decline. Eutrophication could be the responsible factor for this reed decline, as the mudflat contained high concentrations of organic nitrogen and phosphorous. Group III reeds showed the most vigorous growth, demonstrating high values for shoot height, biomass, and panicle length along with moderate stem density. The state of Group III can be described as sub-optimal due to their old age on terrestrial habitat, as a minimum level of seawater is important for vigorous growth of reeds such as sufficient shoot height and photosynthetic capability. Reed height and panicle length have been shown to be recently declining in Suncheon Bay. These results indicate that old and rotting parts of reeds inhibit reed growth and that removal of these parts can have positive effects on shoot height and biomass.
