Phenotypic analyses on plant groups (control and stressed) of durum wheat grown with different N concentrations.
| Control | Stressed | % RR | |
|---|---|---|---|
| PH (cm) | 54.25 ± 2.67 | 44.09 ± 1.78 | 18.73 |
| FLA (cm2) | 16.73 ± 1.65 | 5.28 ± 0.81 | 68.44 |
| FLDM (g) | 0.061 ± 0.002 | 0.019 ± 0.001 | 68.85 |
| NCPP | 4.14 ± 0.4 | 1 ± 0.01 | 75.86 |
| NSPS | 24.6 ± 1.21 | 16.09 ± 1.09 | 34.65 |
| SDM (g) | 0.37 ± 0.002 | 0.14 ± 0.04 | 62.16 |
| KNPS | 20 ± 1.155 | 5 ± 0.58 | 75 |
| KWPS | 0.65 ± 0.034 | 0.15 ± 0.02 | 76.49 |
For each parameter, mean values (±standard error) and relative reductions between control and stressed conditions are presented.
PH: plant height; FLA: flag leaf area; NCPP: number of culms per plant; NSPS: number of spikelets per spike; SDM: spike dry matter; FLDM: flag leaf dry matter; KNPS: kernel number per spike; KWPS: kernel weight per spike; RR: relative reduction.
