GRA.LE.D. (GRApevine Leaf Digitalization) is free raster graphic software created for digital analysis of Vitis leaves based on: • the standard ampelographic measurements suggested by the OIV (International Organization of Vine and Wine: 2nd Edition of the OIV descriptor list for grape varieties and Vitis species); • non-OIV descriptors; • landmark coordinates.
During morphological description of grapevine cultivars have discovered that leaf provides numerous data which could be statistically analyzed. For facilitating objective description, we created a free software which we think may help in this process. We appreciate your feedback, any suggestions or ideas are welcome, and please feel free to send us your questions about the GRA.LE.D software.
