Table 10 Plant variables measured in seedlings under greenhouse conditions determined at destructive harvest of plants on day 60 after germination

Total leaf area (cm²)

TLA

Surface area for every mature leaf of the plant, including cotyledons but excluding emerging leaves around the plant’s apex, was measured using a Li-COR Model 3100 Area Meter (Li-COR). Total leaf area was calculated as the cumulative sum of the surface area of all leaves.

Petiole fresh and dry weight (g plant⁻¹)

P_FW/P_DW

Petioles were cut off from the plant and weighed fresh and after drying at 105°C for 48 hours.

Leaf fresh and dry weight (g plant⁻¹)

L_FW/L_DW

Leaves, excluding petioles) were cut off from the plant and weighed fresh and after drying at 105°C for 48 hours.

Stem fresh and dry weight (g plant⁻¹)

S_FW/S_DW

The stem cut off from the plant and weighed fresh and after drying at 105°C for 48 hours.

Root fresh and dry weight (g plant⁻¹)

R_FW/R_DW

Roots were cut off from the plant and weighed fresh and after drying at 105°C for 48 hours.
