Which outcome impacts xylem transport when excessive soil salinity constrains root water uptake?

💡 Explanation

Salinity reduces root water absorption via osmotic pressure, inhibiting the cohesion-tension mechanism in xylem. Therefore, the transpiration stream decreases because water potential gradients are disrupted, rather than optimized transport or enhanced carbon processes occuring efficiently.
