| 摘 要： | 通过Na2CO3和NaHCO3以质量比1∶3配比,对供试水稻材料进行碱胁迫处理。结果表明:4份参试材料0.25%处理浓度下SOD的活性均高于0.20%处理,龙粳29活性最高,最低为龙育05-158;随着碱处理浓度增大,POD活性呈逐渐上升的趋势,长白9号的POD活性最大,其次是龙粳29,龙育05-158活性相对较低;碱胁迫后,MDA均随处理浓度增大含量上升,两者呈线性正相关,长白9号MDA含量相对最低,抗碱胁迫能力较高。

| Abstract: | With the mass ratio of Na2 CO3 and NaHCO3 was 1：3,the alkaline stress on rice was studied. The results showed that the activity of SOD of 4 materials under concentration of 0. 25% were higher than under the 0.20% treatment, the highest activity was Longjing 29,and the lowest was Longyu 05-158; With the increasing of the concentration of alkali treatment, POD activity showed a gradual upward trend, the highest POD activity was Changbai No. 9, followed by Longjing 29, the relative activity of Longyu 05-158 was lower; after alkaline stress, MDA content were increased with increasing of the treatment concentration, a positive linear correlation between the two, Changbai No. 9 with relatively lower MDA, higher ability salt-stress. |
