Survival rate and biomass of both species did not differ with salinity. In K.obovata seedlings, Na+ concentration in root increased significantly by 4% salt treatment, and ratio of Na+ to K+ increased in hypocotyl and root. In A. marina seedlings, Na+ concentration and ratio of Na+ to K+ in every plant part increased significantly by 2-4% salt treatment. Leaf alanin betaine (AB) concentration did not differ with salt treatment, whereas glycine betaine (GB) concentration in K. obovata and A. marina increased with increase in salt treatment., 論文}, pages = {49--53}, title = {水耕栽培下における塩濃度の違いがヒルギダマシ (Avicennia marina)とメヒルギ (Kandelia obovata)稚樹の生育および樹体内のイオン含有量に及ぼす影響}, volume = {40}, year = {2014} }
