How Soil Salinity affects the Stomatal Conductance of Baccharis salicifolia (Mulefat/Seepwillow)

This is a poster presentation demonstrating the project our group has been working on. We hypothesize that the stomatal conductance of mulefat will decrease as soil salinity increases in both pre-rain and post-rain conditions because the plant tries to absorb salt water. However, the salt water cannot pass through plant tissue and draws water out of the plant. Since plant requires water for photosynthesis, water being drawn out means less water is available for the plant to do photosynthesis. We have tested our hypothesis by collecting soil samples in Legacy park, and recorded stomatal conductance by using a leaf poromete
