摘要： 为研究不同水稻品系在芽期耐盐性，为今后培育耐盐品种提供优良种质资源，本研究以7个水稻品系为实验材料进行芽期耐盐试验，用不同浓度NaCl（盐浓度分别为0、0.125、0.15、0.2 mol/L）胁迫后，对水稻的发芽势、发芽率、根长、芽长、芽鲜重以及主根数目进行测定分析，并通过多元分析对各品种相关指标进行统计分析。试验结果表明：随着盐浓度的升高，不同水稻品系的各项指标均有不同程度的降低。其中，0.15 mol/L盐处理下，‘S83’，‘S85’号水稻品系表现出一定的耐盐性，‘S88’号水稻品系表现出较强的耐盐性。多元统计分析结果表明，在高盐胁迫下‘S88’号水稻品系具有较强的耐盐性。

Abstract: To investigate the salt tolerance of several different rice strains and provide good germplasm resources for salt-tolerant breeding, 7 rice varieties were used in the study. With different NaCl concentrations (0, 0.125, 0.15, 0.2 mol/L), the germinating energy, germinative percentage, root length, shoot length, fresh weight of shoot and main root number were measured and then were analyzed with multivariate analysis method. The results showed that all the testing indexes of different rice varieties decreased with varied degrees. Under salt stress of 0.15 mol/L concentration, ‘S83’ and ‘S85’ showed certain tolerance and ‘S88’ showed a relatively strong tolerance. The results of multivariate analysis indicated that ‘S88’ had stronger salt tolerance.
