摘要
本文报道白菜(BrassicachinensisL.)种子经低剂量γ射线辐照后,苗期植株体内抗坏血酸氧化酶、多酚氧化酶、过氧化氢酶活性及过氧化物酶同工酶、酯酶同工酶酶谱的变化。多照后白菜幼苗的抗坏血酶氧化酶、多酚氧化酶活性提高,过氧化物酶同工酶、酯酶同工酶酶谱发生变化,但辐照对白菜幼苗过氧化氢酶活性的影响表现有高有低。这些变化的总效应可能是促使植物抗性增强,刺激生长,促进发育,提高产量的重要原因。
The changes in activities of ascorbate oxidase,polyphenol oxidase,catalase and zymo-gram of peroxidase isoenzyme,esterase isoenzyme in pak-choi seedlings induced by low-dose ̄(60)Co-γrays irradiation were studied.The results indlcated that the activities of ascorbate oxi-dase and polyphenol oxidase were enhanced.Zymogram of peroxidase isoenzyme and esteraseisoenzyme also ckanged.And the effect of ̄ 60Co-γ ray on catalase was different.All thesecbanges indlcated the possibility of enhancing plant resistance, promoting growth and raisingthe yield of pak-choi.
