Variation on the Growth Rate of Plants by Submersion of High Turbidity - A Case Study on Salix Species -

Abstract

High turbidity submersion due to torrential downpour is one of the factors that influences the plant growth. This study is focused on analyzing the plant's growth rate for Salix species such as gracilisyla, koreensis, glandulosa when these trees are waterlogged. The length of shoots for this control group in the natural state is 33.4% (gracilisyla), 24.3% (koreensis), 23.9% (glandulosa), however, they stopped growing in submersion. Compared to the leaf number of Salix species of this control group in the natural state, 144.5% (gracilisyla), 77.3% (koreensis), 40.3% (glandulosa) in the natural state 30 days, in 30 days submersion, the number of leaves is zero except koreensis. In the results of this experiment, Salix species stopped growing quickly when submersed. This study concludes that it is necessary to plant eco-friendly plants around the slope of the reservoir and dam where flooding takes place frequently.

Assessment of hydrological regimes for vegetation on riparian wetlands in Han River Basin, Korea

“…Also, vigorously changed areas are belonging to the P = 0.25 or lower IEPs district area and it is equivalent to totally 95 inundation period per year. As per Kim et al (2013), they stopped growing in submersion, and the number of leaves became only 19.4% in 20 days of submersion with turbidity in the flood season. Therefore, Salix koreensis Andersson in the right bank area was more vulnerable than in the left bank group.…”
