芽期对耐盐性不同的大麦品种 (系 )进行盐胁迫处理。结果表明 ,一定盐浓度下 ,耐盐性强的品种的相对发芽率、相对发芽脂数及相对萌发活力指数大于盐敏感品种 ;耐盐性中等品种 (系 )的各个指标介于耐盐性强的品种和盐敏感品种之间。上述三指标综合起来可反映植株芽期耐盐性的强弱。
At the bud stage, barley varieties with different salt tolerance were treated with salt stress. The results showed that under certain salt concentration, the relative germination rate, relative germination lipid number and relative germination vigor index of varieties with high salt tolerance were greater than that of salt sensitive varieties. The indexes of moderate salt tolerance varieties (lines) Between varieties and salt-sensitive varieties. The three indicators can be combined to reflect the strength of plant salt-tolerance at the bud stage.
