四种苔藓植物提取液对二种蓼科植物种子萌发和幼苗生长的影响
Effects of aqueous extract of four mosses on seed germination and early seedling growth of two Polygonaceae plants
摘要
Abstract
In this paper,the possible influences of the aqueous extracts of four bryophytes(Sphagnum ovatum,Fissidens cristatus,Hypnum callichroum and Polytrichum commune)on the seed germination and young seedling growth of two vascular plants(Rumex crispus,Polygonum cuspidatum)were investigated.The results showed that the aqueous extracts of these four mosses didn't affect seed germination.However,the crude aqueous extracts of H.callichroum,S.ovatum and F.cristatus inhibited the vigor indices of R.crispus.Furthermore,the crude aqueous extract of F.cristatus significantly enhanced its dry seedling mass,and F.cristatus and S.ovatum significantly inhibited its seedling elongation.For P.cuspidatum,the crude aqueous extracts of four mosses had little effects on its vigor indices and dry mass,but the aqueous extract of F.cristatu had significantly negative influences on its seedling elongation.The possible mechanism that the aqueous extracts of these four bryophytes influencing seed germination and seedling growth of these two vascular plants was not determined.More studies are needed.关键词
