摘要
经激光辐射玉米种子的幼苗中 ,过氧化物酶(POD)和过氧化氢酶(CAT)活性均增高 ,抗坏血酸过氧化物酶(AsAPOD)活性下降 ,谷光甘肽(GSH)含量增加。
The dry maize seeds were irradiated by He-Ne laser at power densities of2.8,3.8and5.4mW·min -1 ·m -2 ,respec-tively,and the corresponding irradiating periods lasted5s,50s and500s.As a result,the POD and CAT activities of maize seedlings inoreased while their AsAPOD activity decreased and their GSH contents increased.Consequetly,the improvement of the active oxygen metabolism for plants groeing up from the seeds being irradiated could be expected.
