X-ray imaging of 30 year old wine grape wood reveals cumulative impacts of rootstocks on scion secondary growth and harvest index

These usage notes are included as a ReadMe.txt file with the data. This dataset consists of 336 .tif files represeting 2D slices of X-ray CT reconstructions from the scions of 112 grafted vines (3 slices per vine). The filename indicates the following data for each image separated by underscores: scion_rootstock_row_column_slice. Scion is either "Cab" or "Chard" for Cabernet Sauvignon and Chardonnay, respectively. Rootstock indicates the rootstock the scion was grafted to, one of the following 15 varieties: Freedom, Ramsey, 1103 Paulsen, 775 Paulsen, 110 Richter, 3309 Couderc, Kober 5BB, SO4, Teleki 5C, 101-14 MGT, 039-16, 140 Ruggeri, Schwarzman, 420 A, and K51-32. Data from the vine in position row 10, column 3 was mislabeled for its rootstock (the files are labeled as "wrong rootstock") and should be ignored, but it is included for completeness. Row and column represent where in the vineyard the vine was taken from, which can be found on the included map in the .pdf named "vineyard_map.pdf". Each of the three slices is named as "Slice XXX" where XXX indicates the voxel number along the z axis of the original X-ray CT reconstruction the slice was taken. Embedded in each .tif file is landmark data indicating the boundaries of the early and late ring wood for rings 1-8, the remaining outer rings, and the cambium. Viticultural data associated with these vines can be found posted on the GitHub repository at https://github.com/DanChitwood/grapevine_rings
