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 Na2CO3 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.
