- 論文の詳細を見る
Rice plants were grown hydroponically in the presence of either NaCl, sea water, or polyethylene glycol (PEG : average molecular weights of 7,800-9,000) at an osmotic potential of up to 186 mOsmol/kg, equivalent to 100mM NaCl or 20% sea water, and the growth and mineral composition of the plants were compared. NaCl was the most detrimental agent, followed by sea water and PEG. Mineral contents, including nitrogen, phosphorus, potassium, and calcium were not significantly affected by the treatments. Removal of silicate from the culture solution brought about a more severe growth reduction in rice plants subjected to 100mM NaCl stress. In the plants which received silicate, the contents of sodium in the shoots were nearly half of those in the shoots of plants which did not receive silicate.
