Phytotoxic Ozone Dose-Response Relationships for Durum Wheat (, Desf.).

Ozone (O) pollution poses a significant threat to global crop productivity, particularly for wheat, one of the most important staple foods. While bread wheat () is unequivocally considered highly sensitive to O, durum wheat () was often found to be more tolerant. This study investigated the O dose-response relationships for durum wheat in the Mediterranean region, focusing mainly on grain yield losses, and utilizing the phytotoxic ozone dose (POD) metric to describe the intensity of the stressor.

A regional scale flux-based O risk assessment for winter wheat in northern Italy, and effects of different spatio-temporal resolutions.

Tropospheric ozone (O) is a secondary atmospheric pollutant known to cause negative effects on vegetation in terms of physiological oxidative stress, growth rate reductions and yield losses. In recent years, dose-response relationships based on the O stomatal flux and effects on the biomass growth have been defined for several crop species. This study was aimed at developing a dual-sink big-leaf model for winter wheat (Triticum aestivum L.
