摘　　要：水稻种子萌发过程中，保水剂促进淀粉转化为可溶性精，不同浓度的保水剂对淀粉转化的促进作用没有显著差异；保水剂能提高种子呼吸强度，且存在浓度差异。矿质元素对水稻幼苗生长发育具有促进作用，Si和Mo明显促进幼苗生长和根系发育，Cu有利于叶片生长和根系分化。保水剂结合矿质元素能进一步提高各种矿质元素的相应作用。WRR brought about transform starch into soluble sugar in germination of riceseeds. There was no variance among concentrations of WRR for promotion of the starchtransform. WRR enhanced respiratory intensity of the seeds,and there was variance among WRR concentrations. There were promotions of several mineral elements ongrowth and development of rice seedling. Either silicon or molybdenum promotedplantlets growth and development of root system. Copper favored growth of leaves anddifferentiation of root system. Combinied with WRR,the effects of the mineral elementswould be intensified further.
