Abstract：The colonization of Piriformospora indica in the roots and its effects on growth and phosphorus absorption of lettuce plants were investigated under four different phosphorus levels [recommended dose (RD),50％ RD,25％ RD and non-phosphorus (NP)] by pot experiment.The results showed that P.indica colonized the root of lettuce with 72％ in the experiment.The SPAD value of plants colonized by P.indica was increased significantly by 23.6％,13.5％ and 11.3％ under RD,50％ RD and 25％ RD treatments as compared to the control without inoculation of P.indica.The fungus was capable of improving the shoot and root biomass of lettuce under different phosphorus levels,especially,the fresh weight of shoot was nearly equal between 50％ RD + P.indica and RD (without P.indica).P contents of the colonized plants were 1.25,1.18,1.48,1.71 times under RD,50％ RD,25％ RD and NP as compared to the control,respectively.Therefore,P.indica can increase phosphorus absorption in lettuce and promote growth of lettuce.
