| 摘 要： | 为了解低温胁迫下水杨酸(SA)时木槿幼苗抗寒性的影响。用0.1 mg·L~(-1)、1 mg·L~(-1)、10 mg·L~(-1)、100 mg·L~(-1)和1 000 mg·L~(-1)五种不同浓度的SA预处理木槿种子,研究SA对木槿幼苗抗寒性的影响。结果表明,SA处理木槿种子使其幼苗超氧化物歧化酶(SOD)、过氧化物酶(POD)活性和脯氨酸含量提高,相对电导率降低,说明SA处理可增强木槿幼苗的抗寒性,且以100 mg·L~(-1)的处理效果较好。

| Abstract: | The experiment studies the effects of Salicylic Acid(SA)on Anti-cold of Hibiscus syriacus L seedlings by using five different concentration(0.11 mg·L~(-1)、1mg·L~(-1),10mg·L~(-1)、100mg·L~(-1)和1000 mg·L~(-1))of SA to treat Hibiscus syriacus L Seeds.The results indicated that the activity of superoxide disrnutase(SOD)and peroxidase (POD),the content of proline were increased,while relative electrical conductivity was declined in Hibiscus syriacus L seedlings.Result from cluster analysis shows that SA can enhance anti-cold of Hibiscus syriacus L Seedlings, and 100 mg·L~(-1)SA is the best treatment concentration. |
