x Grafted onto eggplant ‘EGG203’ rootstock, tomato H7996 rootstock or NG, Non- Grafted.

y P1 probability that variation between means for EG203 vs. H7996 across varieties could occur by chance. A P value < 0.05 indicates that means are significantly different according to Fisher’s F test.

z P2 probability that variation between means for grafted vs. non-grafted across varieties and rootstocks could occur by chance. A P value < 0.05 indicates that means are significantly different according to Fisher’s F test.
