Abstract: According to the principle of adjust measures to local conditions to choice the fine strains for afforestation,at the same time make mycorrhizal biological technology applied to production practice preferably. The effect of ectomycorrhizae on growth and microelement absorption of potted Pinus massoniana seedlings was studied in a greenhouse,by inoculating Pisolithus tinctorius,Cenococcum geophilum,Cantharellus cibarius,Suillus luteus respectively and control group,under the conditions of four levels water stress that make the relative water content of soil,to moisture conditions,light water stress,moderate water stress and severe water stress. Results showed that ectomycorrhizae significantly improved growth (P=0.01),ground diameter (P=0.01),and biomass (P=0.01) of P. massoniana seedlings with drought stress. And the double factor analysis of variance showed that highly significant differences (P=0.01) were also noted between the various strains,moisture,and the interaction of strains and water. The seedling by inoculating Cenococcum geophilum had the best growth increases for height (27.8%) and diameter (52.9%) compared to control group under the conditions of moderate water stress. And the seedling by inoculating Suillus luteus Sp1 had the best increased for biomass (230%) compared to control group. Ectomycorrhizae fungi could effect the seedling to absorption of microelement under the conditions of water stress. The seedling by inoculating Suillus luteus Sp1 ,had the high content of Fe,Mn,Cu,and Zn,and compared to control group,seedling microelement absorption increased for Fe (135%),Mn (33%),Cu (155%),and Zn (96%) under the conditions of moderate water stress. In addition,the seedling by inoculating Suillus luteus Sp1 ,had the best increased for Fe (47.9%),Mn (46.1%),Cu (130.7%),and Zn (49.0%) compared to moisture conditions,under the moderate water stress. Thus,inoculation with Suillus luteus Sp1 undergoing moderate stress could increase biomass, improve seedling absorption of microelements, promote seedling growth, and enhance seedling drought resistance.[Ch,1 fig. 3 tab. 15 ref.]
