Abstract: The main research objective was to study if symbiotic microorganisms can be used in high quality grape grafted saplings production technologies in nursery gardens. For the purpose the laboratory and fi eld methods were used. Some variants with fungus-aulophyte introduction as well as spontaneous inoculation were compared. The standard industry techniques were used to defi ne the biological effi ciency and grape saplings unifi cation/commonality indicators. The number of the main ecologo-trophic microorganisms were assessed by the means of soil suspension inoculation on the solid nutritional medium, the mineralisation process intensity indicators were defi ned. Sapling root inoculation with Arbuscular mycorrhizal fungi positively infl uenced the environmental stress adaptation of the plant, which was observed as an increased kidney blooming dynamics which was 1,3-2 times higher in comparison with control; and the initial foliage growth dynamics was 1,3-2 times more intensive in the fi rst two weeks after planting comparing with the control. Biological activity effi ciency of the elevated grape plant part was apparent; the leaf surface area was expanded by 14,0-42,1 %, the scion average length pulled out by 10,8-28,5 %, leaf surface area growing was signifi cantly more intensive in June-August period. Risogenesis was stimulated – the total number of roots increased by 1,3-1,6 times, 2 mm roots increased by 1,2-2,6 times, the total thickness of roots increased by 1,3-1,8 times. Microbiological activity growth of the soil rhizosphere was observed: the quantity of ammonifi ers grew by 1,6 times, mineral nitrogen immobilisers increased more than by 2,5 times, oligonitrofi ls – by 3,1 times, pedotrofs – by 3, 5 times, micromycetes – by 1,7 times. Steady growth of grape saplings survival in the nursery in environmental stressful conditions is recorded (12,0-27,1 %) as well as an increased standard saplings exit (by 19-24 %).
