摘　　要：为了解不同处理对薯蓣块茎休眠相关酶活性的影响,结合不同浓度赤霉素处理和浸泡覆膜法两种处理方式,研究了不同处理对薯蓣块茎在休眠过程中相关酶活性的影响。结果表明:低浓度赤霉素处理可以使薯蓣块茎中的淀粉酶活性上升,为萌发提供物质和能量保障,使块茎提前萌发,但是高浓度的赤霉素会延长萌发时间。浸泡覆膜法可以大幅度的提高薯蓣块茎的呼吸作用,从而减少薯蓣块茎的休眠期。To understand the effect of difference treatments on enzyme activity related to dormancy of dioscoreaceae tuber, we used different concentrations of gibberellin treatment and laminate soaking methods, different treatment cultivated dioscorca enzyme activity. The resuhs showed that： solution with low concentration of gibberellin can make the amylase activity in the tubers of yam increased, which can provide substance and energy to make the tuber sprout earlier. However, solution with high concentration of,gibberellin wiU extend the sprout duration. Soak laminating method can greatly improve the respiration of yam tubers, and thus shorten the dormancy of the yam tuber.
