Species | Soil treatment | Initial SWC (outer pot, % g g−1) | Final SWC (outer pot, % g g−1) |
---|---|---|---|
Sorghum | 1. Moist primary/moist nodal | 12·5 | 11·5 |
2. Moist primary watering withheld/ moist nodal watering withheld | 12·5 | 5·14 | |
3. Moist primary/dry nodal without evaporation | 2·5 | 1·25 | |
4. Moist primary/dry nodal with evaporation | 2·5 | 0·74 | |
Millet | 1. Moist primary/moist nodal | 12·5 | 11·3 |
2. Moist primary watering withheld/moist nodal watering withheld | 12·5 | 3·82 | |
3. Moist primary/dry nodal without evaporation | 2·5 | 1·19 | |
4. Moist primary/dry nodal with evaporation | 2·5 | 0·66 |
Inner pots were at 12·5 % SWC. Treatments describe the moisture conditions in the inner pot around the primary (seminal) roots and in the outer pot around the nodal roots.
