Modelling crop yield ozone

This research paper evaluates the effects of ozone (O3) pollution on wheat crop growth and yield, specifically testing the relationship between stomatal ozone flux and leaf senescence.

• The study suggests that accelerated leaf senescence is likely the primary ozone effect impacting crop yield in most agricultural settings, as negative effects on photosynthesis were only observed in conjunction with O3-induced senescence.
• Phytotoxic Ozone Dose (POD), simulated via a multiplicative stomatal conductance model, proved to be a more effective predictor of physiological response than AOT40 or 24-hour mean concentrations, and it successfully accounted for differences between peak and high background treatments.
• Experimental data from 2015 and 2016 involving two wheat cultivars exposed to O3 levels between 22 and 57 ppb showed that leaf senescence occurred earlier as average POD increased, though the two cultivars exhibited very different responses.
