The influence of ectomycorrhizal fungi on spruce (Picea abies) seedlings growth, nutrition and water status is presented. Seedlings were produced in nursery by standard procedure. The origin of seeds was spruce seed stand on Jastrebac Mt. (Serbia). Liquid culture of six ectomycorrhizal fungi, common symbionts of Picea spp.: Boletus badius, Hebeloma crustuliniforme, Pisolithus arrhizus, Suillus bovinus, Rhizopogon sp. was used in the experiment with four replicates with 50 seedlings. Roots were dipped in this gelatinous mass which has covered them. Morphometric and some physiological properties were analyzed before and after first and second vegetative season. After the first season the survival percent was better for 18% in treated plants. It was significant influence of ectomycorrhizal fungi on seedling height (average for 2.4 cm); number of new twings was more numerous for 1.3, root collar diameter for 1.2 mm and root volume for 0.7 cubic cm. It was higher content of mineral elements (N,P,K,Ca and Mg) in needles in treated plants after first and especially after second season. Water regime properties, water potential, transpiration intensity, total water content, were also better in treated plants.
