摘要: 磁场处理番茄种子,观察种子的发芽率,幼苗的过氧化氢酶(CAT)和过氧化物酶(POD)活性的变化,以及对过氧化物酶同工酶的影响。实验结果表明,磁场强度在1000~2000GS范围内,种子发芽率最高,过氧化氢酶和过氧化物酶活性最高,过氧化物酶同工酶活性亦最高,磁场强度高于3000GS时,种子发芽率及其酶活性随之降低。

Abstract: After treatment tomato seeds with magnetic field, observed the germination rate, the change of the catalase (CAT)and peroxidase (POD) and the effect on the peroxidase isoenzyme.The results revealed that the seeds germination rate is highest, the activity of the catalase (CAT) and the peroxidase (POD)is highest. The activity of the peroxidase isoenzyme is highest too, when magnetic field is in range 1000~2000 GS.The seeds germination rate and the activity of CAT and POD is lower, when the intensity of magnetic field is higher than 3000 GS.

Key words: Magnetic field, Tomato, Catalase, Peroxidase, Peroxidase isoenzyme
