THE INFLUENCE OF PHYTOSANITARY TREATMENTS ON THE SOIL YEAST LOAD IN VINEYARD IAȘI, ROMANIA.

The aim of this study was to determine the influence of phytosanitary treatments on the soil yeast load in Vineyard Iași. The experiment study included 4 local grape varieties: Busuioacă de Bohotin, Fetească Albă, Fetească Neagră and Fetească Neagră (from Collection of grape varieties) from viticultural center Copou. The samples were taken at 3 depths: 5-7 cm, 10-15 cm, 15-20 cm. To determine the influence of phytosanitary treatments on the diversity and distribution of yeasts, 2 soil samples were taken in the 5-7 cm shoot phenophase at 10-day intervals. The yeast strains isolation and obtaining of the pure cultures was completed by successive replications using sowing on solid nutrient media technique. [ABSTRACT FROM AUTHOR]
