Experiments have been conducted with a purpose of investigating effects of NaCl concentration on the growth, and absorption of inorganic nutrition by Limonium tetragonum in a deep flow culture, with the ultimate purpose of providing basic data for utilizing it in afforestation of seashore reclaimed lands.
In this research, Limonium tetragonum has been the subject of experiments over about three months with culture fluid in a system of NaCl concentrations of 0, 200, 400, and 600mM of deep flow culture.
As for the leave number, there were small differences but the amount was not meaningful, and the fresh weight above the ground was higher at NaCl of 400nM, but there was no meaningful differences among the different treatments.
As for the leave color, there were some differences among the different treatments, but the amount was not meaningful. However, the concentration of chlorophyll was higher by a factor of more than two with NaCl 200mM treatment, as compared to the cases of non-treatment, yet, the concentration was even lower than the non-treatment cases when the treatment levels were 400mM and 600mM.
As the concentration level of NaCl increased, Na was absorbed more, but Mg, K, and Ca were absorbed less, in general. Also, as the concentration level of NaCl increased, prolin concentration was seen increased more above the top than root.
Limonium tetragonum is regarded as a plant proper for soil stabilization and afforestation in a landfill damaged by tidal flat landfill in a huge scale land-reclaiming program or in an offshore landfill area, where successful afforestation with ordinary plants is difficult due to salty environment.
