本研究以6份苜蓿种子为试验材料，在实验室内用不同梯度NaCl、NaHCO3混合液模拟盐碱胁迫，测定其发芽率和发芽势等指标。结果表明：随着混合盐碱胁迫浓度增加，参试的6个品种苜蓿种子发芽率和发芽势等指标均下降，但下降程度有所不同，根据发芽势和发芽势等指标分析，耐盐碱能力由强到弱依次为美国343＞敖汉＞龙牧803＞中苜2号＞公农1号＞龙牧801。
本研究以6份苜蓿種子為試驗材料，在實驗室內用不同梯度NaCl、NaHCO3混閤液模擬鹽堿脅迫，測定其髮芽率和髮芽勢等指標。結果錶明：隨著混閤鹽堿脅迫濃度增加，參試的6箇品種苜蓿種子髮芽率和髮芽勢等指標均下降，但下降程度有所不同，根據髮芽勢和髮芽勢等指標分析，耐鹽堿能力由彊到弱依次為美國343＞敖漢＞龍牧803＞中苜2號＞公農1號＞龍牧801。

Selecting six kinds of alfalfa seeds as experimental material, different concentra-tion gradient of sodium chloride and sodium bicarbonate were mixed to simulate the saline-alkali stress, meanwhile detected the germination rate and germination energy as indicators. The results showed that as the concentration of complex saline-alkali increases, the germination rate and ger-mination energy of all the tested alfalfa seeds were reduced in varying degrees. According the in-dicators analysis on germination rate and germination energy, saline-alkali tolerance ability from strong to weak were US No.343, Aohan, Longmu No.803, Zhongmu No.2, Gongnong No.1 and Longmu No. 801.
