Growth characteristics of Salicornia herbacea on the coastal reclaimed dredging area

As a basic study on the creation of artificial salt marshes using dredged coastal sediments, the pilot-scale Salicornia herbacea bed was constructed on the reclaimed dredging area in Busan New Port. One hundred of Salicornia herbacea seeds were sown in each plot (1m x 1m) and 20 plots were constructed im March 2010. We investigated the germination, morphology, biomass, leaf chlorophyll and CN content of newly developed Salicornia herbacea monthly from March to November 2010. Germination rate was 7% in 2 months after sowing, but 6% of Salicornia herbacea was established. Shoot length and biomass increased rapidly during summer. Maximum shoot length and biomass were 60.7 cm and 249.4 g FW sht⁻¹, respectively. Leaf chlorophyll content was higher in young shoots. The nitrogen content of the root tissue decreased during summer. The artificially developed Salicornia herbacea bed appeared to grow well on the reclaimed dredging area in Busan New Port.
