A slat-fence wind barrier, installed midfield and oriented east-west, was used to investigate leaf-water potential and stomatal resistance of winter wheat (Triticum aestivum L.) as influenced by barrier-induced microclimate in a semiarid macroclimate. Leaf-water potential, stomatal resistance, and micrometeorological parameters indicated that shelter affected neither leaf-water potential nor stomatal resistance when stress was low. At intermediate stress, leaf-water potential was significantly higher in the sheltered area than in open field. Under high stress, leaf-water potentials of plants hi the two areas did not differ significantly; however, stomatal resistance was higher in the open field than in the sheltered area.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
