Description

The increased atmospheric CO2 concentration (↑[CO2]atm) is not an isolated effect, being accompanied by increases in air temperature and changes in precipitation patterns. In coffee producing regions, drought is considered the main factor affecting growth and coffee production. Coffee has a broad chemical composition, highlighting caffeine and 5-chlorogenic acid (5-CQA), which act in plant defense responses and are important secondary compounds in the final beverage quality. The aim of this work was to evaluate the interaction between ↑[CO2] and water deficit on photosynthesis and caffeine and 5-CQA in Arabica coffee.
