The effects of moisture and mycorrhizal inoculation on stomatal conductance and xylem pressure potential of Faidherbia albida (Del.) A. Chev. were investigated in the semi arid environment of
Sokoto, Nigeria. A complete randomized block design with five replications and factorical combination of three watering regimes (daily for unstressed plant, twice weekly for partially stressed plants and once a week for moisture stressed plants) and three mycorrhizal treatments namely; endomycorrhizal plants, ectomycorrhizal plants and non mycorrhizal plants were used. Both the ecto and endo mycorrhizae significantly (P<0.05)affected the Stomatal Conductance and Xylem Pressure Potential of the plant even under stressed conditions. The use of mycorrhiza is thus recommended as a strategy for efficient water utilization and water conservation.
