When elicited, plants release a large amount of volatile organic compounds (VOCs) in the air, which can act as great communicators and elicitors to neighboring plants and organisms. These VOCs can cause significant interference when testing new compounds against biotic and abiotic agricultural stressors. To mitigate these interferences and ensure that the observed effects and results are solely attributed to the treatments being evaluated, it is crucial to perform plant elicitation trials in total controlled conditions with the use of physical barriers to prevent VOCs exchange between treatments. To investigate the potential interference caused by VOCs, a study was conducted comparing two experimental sets: one performed in an open field using a randomized complete block design (RCBD), and another conducted in total controlled conditions using a completely randomized design (CRD) with adaptations. The study found that, on average, an interference of over 22% was observed for the assessed parameters. This suggests that the exchange of VOCs between treatments in the open field trial leads to significant interference and affects the reliability of the results.</span></span></p> 2024-05-21T00:00:00+00:00 Copyright (c) 2024 Revista Thema
