Effect of water and VPD environment during peak flowering on lint yield of four cotton genotypes (CSX2027, CSX8521, Sicot 80BRF, and Sicot 746B3F) grown across Australian cotton regions from 2006 to 2020.
| Explanatory variable | % Variation | Change |
|---|---|---|
| Water | 27.7 | - |
| VPDMax | +13.0 | 0.001 |
| Genotype | 0 | 0.215 |
| Water × VPDMax | +24.3 | 0.001 |
| Water × Genotype | 0 | 0.200 |
| VPDMax × Genotype | +1.9 | 0.009 |
| Water × VPDMax × Genotype | 0 | 0.521 |
| Total variation | 66.7 | - |
Variation (%) accounted for by including each term in the model is shown. Change was deemed significant at p < 0.05. Peak flower is defined as between 1,000- and 1,450-day degrees.
