| 摘 要： | 用功率密度为２．８ｍＷ／ｍｍ２，３．８ｍＷ／ｍｍ２及５．４ｍＷ／ｍｍ２的Ｈｅ－Ｎｅ激光辐射干种子，辐射时间均分别为５，５０和５００ｓ。发现经激光辐射干种子的玉米幼苗中，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。其综合效果是增强了植物体清除活性氧的能力。

| Abstract: | This paper presents experimental studies in which the drying corn seeds areirradiatedby He-Ne laser at power densities of 2.8,,3.8 and5.4 mW/ mm2,respectively,and the corresponding irradiating times last 5 s, 50 s and 500 s. As a result,the POD and CAT activities of corn seedling are enhenced while their AsAPOD activity isreduced and their GSH contents are increased. Consequently, the improvement of the activeoxygen metabolism for plants the seeds of which have been irradiated can be expected. |
