Short summary
Impacts of soil moisture on de novo monoterpene emissions from several tree species were studied. Mild drought slightly increased MT emissions, but with further progressing drought the emissions decreased to almost zero. Increases of MT emissions were explainable by increases of leaf temperature due to lowered transpirational cooling. The decrease of emissions observed when soil moisture fell below certain thresholds was parameterized, allowing considering impacts of soil moisture in models.
