刺槐根瘤菌溶磷和分泌植物生长素特性的研究
Characteristics of Dissolving Phosphate and Secreting IAA of Rhizobia in Robinia pseudoacacia
摘要
Abstract
Using the methods of phosphate -dissolving circle , Mo-Sb colorimetry and Salkowski colorimetry , the author qual-itatively and quantitatively determined the abilities of dissolving phosphate and secreting IAA of 25 rhizobia strains isolated from Rob-inia pseudoacacia in 6 districts ( counties ) of Shaanxi province .In the qualitative test for phosphate -dissolving ability , it was found that the strain SLCH171 had the strongest ability to dissolve both organophosphorus and inorganic phosphorus ; in the quantitative test for phosphate-dissolving ability , the strain SLCH171 had the strongest ability to dissolve organophosphorus , while the strain SLCH184 had the strongest ability to dissolve inorganic phosphorus , and 10 of 25 strains could dissolve not only organophosphorus but also inorganic phosphorus .The results of determination of IAA -secreting ability showed that 21 strains had the ability to secret IAA, and SLCH184 had the strongest ability among them;the quantitative determination results of IAA -secreting ability of various strains basically conformed to the qualitative determination results .关键词
