| Abstract: | This review presents tropospheric ozone (O3), an air
pollutant affecting agriculture by reducing crop yield and deteriorating quality
of produce. O3 enters leaves through stomata and diffuses within the apoplast,
producing many oxidizing compounds and
affecting various physiological and biochemical
processes, crop growth and yield. O3 affects above and below ground carbon allocation
and its dynamics, N cycling, microbial content and emission of greenhouse gases
(GHG) from soil. This review focuses on the impact of O3 on crop growth with
special emphasis on productivity in Asian region, methods for evaluating O3
responses in field, amelioration of O3 induced injury and providing
dose-response functions for economic assessments. |
