| 摘 要： | 介绍了弧光放电等离子体与梯度磁场相结合来处理植物种子这一新兴的等离子体生物技术。给出了番茄种子(中蔬6号)经不同参数的磁化等离子体处理后的生物效应及种子的抗旱性对比。结果表明:种子中脯氨酸含量明显提高,说明磁化等离子体能通过降低细胞渗透势来增加番茄抗旱性;SOD、POD活性、根系活力和ATP含量增加,表明磁化等离子体可以通过清除植物体内自由基和增强代谢来增加番茄对水分胁迫的抗性。

| Abstract: | Using arc discharge plasma combined with gradual magnetic field to treat seeds is a new plasma biological technology.The biological effect and drought resistance of tomato seeds treated with different plasma parameters were compared.The increasing of proline content indicates that the drought resistance of tomato seedlings could be increased due to reduction of penetration potential of plant cell.Increased SOD,POD activity,root activity and ATP content show that water stress could be alleviated by eliminating the free radicle and increasing metabolism. |

| Keywords: | Magnetized plasma Tomato Drought resistance |
