Ionomic analysis of fresh tea leaves from pruned and unpruned tea plants. (A) Percentage changes in mineral element concentrations with pruning. Percentage change = [(concentration_pruned - concentration_unpruned)/concentration_unpruned]×100%. Elements with concentrations that decreased (B), increased (C) and did not change significantly (D) in fresh tea leaves from pruned tea plants. Values in the figure are the mean of 7 replicate samples per tea plantation (unpruned: n=132, pruned: n=218). Statistically significant differences between groups were tested by the Student’s t test. ***: P ≤ 0.001, **: 0.001 < P ≤ 0.01, ns, no significant difference.
