Abstract: Two grapewine making cultivars, Cabernet Sauvignon and Merlot (Vitis vinifera) , were used in this study to estimate vine vegetative vigour by the remote sensing technique. The results show that the normalized difference vegetation index (NDVI) of grapevines based on on-ground object spectral data distinguished well the intraplot vine vegetative vigour, including shoot length, shoot daily growth rate, leaves areas pervine and N-Tester index. Significant correlations were found between NDVI and shoot length, shoot daily growth rate, leaves areas pervine, or N-Tester index. The results indicate that NDVI could be used for evaluating the grapevine intra-plot vegetative vigour and the GIS distributed NDVI map might be used to distinguish
different grapevine vigour zones.
