The data on the diagonal line from top left corner to lower right corner in the table shows the correlation coefficient of the contents of individual resveratrol and total resveratrols between berry skins and leaves in all germplasms.

^zBerry skin data and.

^yleaf data shows the correlation coefficients among different individual resveratrols from the tissues.

^{* and **} indicate a significant correlation at P<0.05 and P<0.01, respectively.
