摘　　要：为了解苔藓植物提取液对植物的生长调节作用,研究了美灰藓〔Eurohypnum leptothallum(C.Muell.)Ando〕和真藓(Bryumargenteum Hedw.)配子体水提取液对玉米、小麦种子萌发及幼苗生长的影响。结果表明:美灰藓不同浓度提取液对玉米种子萌发无明显影响,对小麦种子萌发有一定的促进作用;不同浓度真藓提取液对玉米种子萌发有一定的抑制作用,对小麦种子萌发无明显影响。美灰藓和真藓不同浓度提取液对玉米和小麦的幼苗生长有抑制或促进作用。Effects of extract from gametophytes of Eurohypnum leptothallum and Bryum argenteum on seed germination and seedling growth of maize and wheat were studied to know its growth regulating function.The results show that different concentration of extract from gametophytes of Eurohypnum leptothallum has no significant influence on maize seed germination,but promotes wheat seed germination to a certain degree.Extract from Bryum argenteum inhibit maize seed germination to some extent,but has no significant influence on wheat seed germination.The extract inhibits or promotes seedling growth of maize and wheat with the variation of concentration,seed treatment and culture method.
