摘要
利用外磁场处理羊草种子 ,并将羊草进行盐 (NaCI)碱 (Na2 CO3)混合胁迫处理 ,结果表明 ,磁场处理不仅促进了羊草的生长 ,而且提高了羊草的抗盐碱性 .磁场使羊草过氧化物酶 (POD)活性提高 ,并且诱发了一条新的同工酶带 .根据羊草的长势及POD活性分析 ,确定羊草最佳的磁处理参数是 30 0mT处理 ,其次是 2 0 0mT .
This paper studied the effect of extra magnetic field and saline alkali stress on the seedling growth of Leymus chinensis .The results showed that magnetic field treatment not only improved the seedling growth of L. chinensis , but also enhanced its saline alkali tolerance. This treatment also increased its peroxidase(POD) activity, and induced an extra POD isozymic band on electropherogram. According to a comprehensive analysis, 300mT and 200mT for 10 minutes were determined as the optimum magnetic field intensity on L. chinensis seeds.
