Abstract
本試驗以水稻台農67號經疊氮化鈉化學誘變純化之突變庫中之品系爲材料，以1/2改良式木村氏水耕液外加150mMNaCl進行秧苗期耐鹽性篩選；試驗結果顯示，大部份品系在鹽分逆境處理後5-7天與第11-14天間產生兩個劇烈轉折變化，鹽害指數由原先較低的情形快速昇高，顯示此兩個時間點對於大部份參試品系耐鹽性具有重要影響。
Seedlings obtained from a chemical mutagenized Tainung 67 mutant population were conducted for the salt-tolerance in a hydroponic system containing 150mM NaCl. The effect of salinity was recorded by salt injury score according to the severity of damage after salt treatment. Most of the mutant lines exhibited two drastic increases in salt injury score at day 5 to 7 days and 11 to 14 days that indicated these two time periods having critical influence on the plant's response to salt. In this study, we developed an effective technique for screening salt-tolerant mutants and obtained manifold fundamental data for salt responses at seedling stage.
