摘要:
为研究不同低温对不同烟草品种的酶活性的影响，以K326和云烟85为材料，于4、6和10 ℃人工智能气候箱中进行低温胁迫。结果表明：在低温胁迫下，POD活性均大于对照组（25 ℃），随着温度的降低而降低；CAT活性均小于对照组，随着温度的降低而降低；10 ℃低温胁迫的烟株幼苗SOD活性大于对照组，而4和6 ℃的SOD活性小于对照组，SOD活性随着温度的降低先升高后降低；K326和云烟85两个品种之间的酶活性存在显著性差异，且K326小于云烟85，即K326可能属于低温敏感型，云烟85可能属于耐低温型。
Abstract:
In order to study the effects of different low temperature on the enzymatic activity of different tobacco varieties,K326 and Yunyan 85 were used as materials to carry out low temperature stress in 4,6 and 10 °C artificial intelligence climate chambers.The results showed that under low temperature stress,the activity of POD was higher than that of the control group,and decreased with the decrease of temperature; the activity of CAT was lower than that of the control group,and decreased with the decrease of temperature; the activity of SOD of tobacco seedlings with low temperature stress at 10 ℃ was higher than that of the control.In the group,the SOD activity at 4 and 6 ℃ was lower than that in the control group,and the SOD activity increased first and then decreased with the decrease of temperature; there was a significant difference in the enzyme activity between K326 and Yunyan 85,and K326 was less than Yunyan 85.That is,K326 may be a low temperature sensitive type,and Yunyan 85 may be a low temperature resistant type.
