Real-time quantitative PCR validation of several selected hormone-related genes in hickory during graft process. Total RNA was extracted from the scion and rootstock of the grafted hickory at different time points after grafting. The histogram shows the relative expression level of these genes with respect to the ACTIN in hickory. The data were analyzed by three independent repeats, and standard deviations were shown with error bars. Significant differences in expression level were indicated by “*”
