- Different letters mean statistically significant differences (within each cut type) for p < 0.05, according to Student’s t test (n ≥ 10)
- DAS: days after sowing; TDR: Total de-rooting; PDR: Partial de-rooting; n.a.: not applicable
- Final leaf area (mm2) was estimated 24 days after sowing. Recovery time is the number of days required for the plants to get their relative growth rate equal to uncut plants
