AI Article Synopsis
- - The study examines the impact of phytotoxic ozone dose (PODy) on visible injuries in the tropical species Astronium graveolens, using structural markers to validate these injuries related to oxidative responses.
- - As the POD increases, so does the observable injury in the plants, measured through different metrics: incidence, severity, and severity leaflet percentages.
- - The effective doses (ED20, ED50, ED80) indicate that the response of Astronium graveolens to ozone is consistent across various climate conditions, suggesting that INC and SF metrics are useful for long-term forest monitoring, while SFL is effective for short-term assessments.
Article Abstract
The present study evaluates the development of visible injury related to phytotoxic ozone dose (PODy) in native tropical species Astronium graveolens Jacq. (Anacardiaceae) and validates the symptoms using structural markers attributed to oxidative burst and hypersensitive responses. Increasing POD was associated with increasing O visible injury using different metrics as the incidence (INC = number of injured plants/total number of plants × 100), severity (SF = number of injured leaves/total number of leaves on injured plant × 100), and severity leaflet (SFL = number of injured leaflets/total number leaflets injured plant × 100). The effective dose (ED), which represents the POD dose responsible for inducing 20 (ED20), 50 (ED50), or 80% (ED80) of visible injury, were used to demonstrate that for this species, the response is similar even when the plants are exposed to diverse climate environments. Further investigation of the INC and SF index may help in long-term forest monitoring sites dedicated to O assessment in forests, while the SFL index seems to be an excellent indicator to be used in the short term to investigate the effects of O
