Abstract: The purpose of this study was to investigate the development of rooted grafted vines of Chardonnay variety in a nursery. It was found out that the performance of green cutting in case of need causes decrease of values of the following biometric parameters: average length, thickness and average length of the mature part of shoots in comparison with the control. The rooted grafted vines variant E (cutting performed on 30th of July) was characterized by lowest parameter values in regard to growth. The root system development of grafted vines: number, thickness and mass of main roots, has been influenced by the green cuttings performed, but in all variants applied the values of biometric parameters were lower in comparison with the control.
