摘　　要：采用6个有代表性的菠菜栽培品种(8#、23#、27#、39#、48#、53#),用浓度为0、0.25%、0.50%、0.75%1、.00%、1.25%、1.50%、2.00%的NaCl溶液对种子发芽作盐胁迫处理,分别观测NaCl胁迫对发芽势、发芽率、发芽指数、活力指数、鲜重等发芽指标的影响。结果表明:NaCl胁迫下,各品种发芽势、发芽率指标均随盐浓度的增加呈波状变化,但发芽指数、活力指数、鲜重则随浓度的增加而先升高后降低。当NaCl达0.5%时,48#品种各项发芽指标均达最高值,且均在其它品种之上,是参试品种中耐盐性表现最好的品种。6 representative spinach cultivars（8# ,23# ,27# ,39# ,48# ,53# ） were used in this experiment. The germination tendency, germination percentage, germination index, vigor index and fresh weight were tested to determine the effects of salt stress at the concentration 0, 0.25%, 0. 50%, 0. 75%, 1.00%, 1.25%, 1.50% and 2.00% . The results indicated that, under the salt stress, the indices of germination tendency and percentage were waveform and the others first rose and then droped with the increasing of salinity. At 0.5% ,48# was superior in each index. The salt tolerance of 48# was the best among the 6 species in every test.
