Monitoring of Vitis vinifera endophyte population

Due to increasing demands to agricultural production it is necessary to fine processes which will increase health of cultural plants and will have positive impact on landscape with potential to increase production. Our work is concerned on grapevine plants (Vitis vinifera) endophytic population. We monitor endophytic population in leaves and stems of four grapevine varieties Pinot Gris, Pinot Noir, Rhine Riesling and Müller Thurgau during year from two vineyards with different ways of wine production, biodynamic production and conventional with use of pesticides. Our concern is to monitor functional and structural changes in endophyte populations and its seasonal changes. Functional changes were determined by measurement of selected plant growth promoting properties of endophyte populations. For monitoring changes in population structure fatty acids methyl esters analysis was used.
