【中文摘要】 本文研究结果表明：在猴头菌丝体生长过程中纤维素酶活力变化趋势为由高到低，多酚氧化酶活力变化趋势为由较低到高再降低。ＡＧ与２·４－Ｄ处理菌丝体提高了这两种酶的活力，但没有改变其变化规律。培养基中还原糖含量随着菌丝体生长由高到低，处理与对照间无明显差异。据此我们认为猴头菌丝体在生长初期可能以纤维素为主，到中期以木质素为主。ＧＡ、２．４－Ｄ可提高二酶的活力并促进菌丝体对碳源的吸收，但不改变纤维素、木质素的利用顺序。二调节剂处理相比，２４－Ｄ对酶活力的提高要好于ＧＡ处理。
【英文摘要】 The study results showed that the changes of activities of cellulase were from high tOlow and those of polyphenol oxidase were from low to high and to low again,Theactivities of two enzymes increased as hyphae were treatmented by GA and 2·4-D,butthe change trend of them were not changed. The content of reduction carbohydrates wasfrom high to low as hyphae growing. There was no difference between treatment and CK. We consider that hyphae used cellulose mainly in initial days and lignin was used mainlyin middle days.2·4-D and GA could enhance activities of two enzymes and capable ofusing carbon resource. But they could not change order of using cellulose and lignin.Comparing treatment of 2·4-D that of GA, the former was better than latter in effectingon activities of two enzymes.
