摘　　要：以国家Ⅰ级重点保护野生植物长喙毛茛泽泻Ranalisma rostratum组培苗为试材,以蛭石、泥炭、蛭石泥炭1∶1混合为移栽基质,统计其移栽成活率、植株叶片数量和叶片宽度,分析不同基质对组培苗成活及生长的影响。结果表明:不同移栽基质中,蛭石泥炭1∶1混合为移栽基质效果最佳,其组培苗移栽成活率为98.33%;其次是泥炭,达96.67%;蛭石最低,为78.33%。3种基质中的组培苗生长势不一,其中与蛭石基质相比,泥炭基质和蛭石泥炭1∶1混合基质中的植株叶片数量多,叶片较宽,根系较发达。The effects of different transplanting media on survival and growth of tissue culturedplants of Ranalisma rostratuma Class I national priority species for protection were analyzed in this paper.The survival rate,the number of plant leaves and the width of the leaves were counted in the transplanting medium of larvae,peat and vermiculite peat 1:1.Results showed that the best medium for transplanting was vermiculite peat 1:1mix,the survival rate of the tissue cultured plants was 98.33%,followed by peat,up to 96.67%;vermiculite minimum,78.33%.The growth rate of the tissue cultured plants in the three transplanting media was different,compared with the vermiculite matrix,the number of leaves in the mixed matrix of peat matrix and vermiculite peat 1:1 is wide,the leaf is wider and the root system is more well developed.
