| 摘要: |
| 以不同浓度(0、0.5、1.0、1.5 mmol/L)的STS溶液对绿蕾期牡丹“朱砂垒”品种全株进行喷雾处理,测定了整个花期花瓣中超氧化物歧化酶(SOD)活力、超氧阴离子(O</sup>2)产生速率、可溶性蛋白质含量、呼吸速率及丙二醛(MDA)含量的变化,观察记录了不同处理对花寿命的影响。结果表明,不同浓度的STS均能提高花瓣中SOD活力和可溶性蛋白质含量,使O</sup>2产生速率、呼吸速率和MDA含量降低,花寿命有不同程度的明显延长。其中以1.0mmol/L处理效果较佳。 |

| Abstract: |
| The tree peony(zhu sha lei)in green period was treated with different concentrations of STS(0,0.5,1.0,1.5 mmol/L). The changes of SOD activity,the producing velocity of superoxide anion,soluble protein content,respiratory rate and MDA content were measured,the effects of the florescence with different treatments were observed and recorded. The results indicated that the different concentrations of STS can increase SOD activity and soluble protein content in the petals,reduce the producing velocity of superoxide anion,respiratory rate and MDA content,and the florescence was prolonged obviously with different concentrations of STS. The 1.0 mmol/L is the best. |
