| 摘 要： | 分别用0,50,100,200,300 mmol/L NaC1溶液处理6个品种的小黑麦幼苗,15天后测定其净光合速率、蒸腾速率、气孔导度、胞间CO2浓度,以及根长、苗高、鲜重.结果表明,50 mmol/L NaC1处理对小黑麦的光合速率和幼苗生长有轻微促进作用,随着NaC1浓度增大,幼苗表现为光合速率、蒸腾速率、气孔导度降低,胞问CO2浓度也呈现规律性变化,幼苗生长受到抑制.综合比较以上指标,在供试的6个小黑麦品种中,抗盐性强的品种有NTH1888和NSWH11,WOH939抗盐性中等,抗盐性弱的品种为黔中3号、劲松49、澳洲黑麦.

| Abstract: | Six varieties of triticale cultivars are treated with NaCl in 0,50,100,200,300 mmol/L concentrations,then the photosynthetic rate,transpiration rate,stomatal conductance,intercellular CO2 concentration,root length,height of seedling and fresh weight are examined after 15 days.And the result of the experiment shows that the 50 mmol/L NaCl process can promote lightly the photosynthetic rate and the growth of the seedlings.With the increase of the concentration of NaCl,the net photosynthetic rate,transpiration... |
