摘　　要：本文报导了采用Ｈｅ－Ｎｅ和Ａｒ＋两种激光器，分别对在酿酒过程中起糖化作用的根霉菌株孢子悬浮液进行辐照，再经继代培养后，其生长速率、糖化酶活性和培养菌箱上生长情况的观察比较结果。研究表明：采用激光辐照诱变方法，能简便快捷的选育出优良根霉菌株，并在酿酒生产中获得应用，产生经济效益。In this paper,we report the comparison results about biochemical and morphological parameters of rhizogillus strain,some of whose suspension is subjected to laser irradiation and some not,such as growth rate,the diameter of strain,the size of sporangium,saccharified enzyme activity.The He-Ne and argon laser are used respectively in the experiments.Our study show that the good strain of Rhizogillus can conveniently and rapidly be got by using proper laser irradiation mutagenesis,which would be used in the wine making industry and have a good economical benefit.
