NR activities in the leaves (A) and roots (B); GS activities in the leaves (C), and roots (D) of M9T337 seedlings treated with K0 (0 mM K+), K3 (3 mM K+), K6 (6 mM K+), K9 (9 mM K+), or K12 (12 mM K+) in 2018 and 2019. Each treatment had three biological replicates and the assays were repeated three times. Vertical bars indicate ± SD (N = 3). Different letters indicate statistically significant differences (P < 0.05).
