Simulating the impact of (“long-distance” or “root-to-shoot”) hormonal signaling and non-uniform soil water distribution on plant transpiration
Simulating the impact of (“long-distance” or “root-to-shoot”) hormonal signaling and non-uniform soil water distribution on plant transpiration
Highlights: In response to non-uniformly distributed soil water, root water uptake and actual (whole plant) transpiration was simulated using R-SWMS as part of the soil dried. These variables varied widely (reduction between 10 and 55 percent) between plants with different controls of stomatal cond...

Highlights: In response to non-uniformly distributed soil water, root water uptake and actual (whole plant) transpiration was simulated using R-SWMS as part of the soil dried. These variables varied widely (reduction between 10 and 55 percent) between plants with different controls of stomatal conductance, i.e. controlled by leaf pressure and/or by the concentration of a hormonal signal triggered by low root water potentials in dry soil regions. Hormonal regulation of transpiration was effective only for a limited time, when water flow out of drying soil regions was sufficient to transport hormones to the shoot. |
