영문 초록

Absba`t This experiment was conducted to investigate the effect of various type of Magma seawater (MSW) concentrations on plant growth and useful mineral contents in Bletilla striata. In the RO (Reverse Osmosis) and ED (Electronic Distal) treatment, hardness of medium was poored in 3.0 g/L gelrite but increased in 8.0 g/L plant agar, 38,000 and 2,000 g/cm2 respectably. We analyzed the morphological and physiological characteristics differences of B. striata treated various MSW. Survival frequency of plant and growth (shoot length, shoot diameter, root length. root diameter, shoot/root ratio) were significantly increased in RO and ED treatment at 50% and 10%, especially. Chlorophyll contents in ED treatments were higher than those in control and RO treatment. The content of strontium (Sr) in 20, 50, 75, 100% ED treatment, were higher than those in the control and RO, ED 1, 5, l0% treatment. These results showed that treatment of ED with the range of 20- 100% could be used to supply the strontium enriched orchid plant. It is considered that MSW may be applied for use in Magma seawater to promotion of growth and produced functional plant.
