Table 4.
Comparison of the main phenolic groups content (mg/kg FW ± SE) between the two analyzed years (2021 and 2020) in seeds of R. × R. glauca and R. corymbifera. Different lowercase letters indicate statistical differences between genotypes in each year, and different capital letters indicate statistically significant differences between genotypes (A, B) or years (X, Y) (Tukey test at ‘***’ = 0.001; ‘**’ = 0.01; ‘*’ = 0.05; NS ‘no statistical difference’).
