Agronomic techniques effectively modified the xylem structure of Coffea arabica L., leading to both anatomical and functional changes, thereby highlighting the vascular system’s remarkable plasticity in this species.

Abstract

The cultivation of Coffea arabica L. holds significant socioeconomic and historical importance in Brazil; however, it is consistently affected by seasonal drought and limited water availability across major production regions. To mitigate the adverse effects of water availability on coffee plants, adopting agronomic practices is essential. This study aimed to evaluate the influence of different agronomic practices on the wood anatomy of C. arabica L. and their implications for water conduction. Coffee plants were cultivated under five treatments—polyethylene film (mulching), Urochloa decumbens (Stapf) R.D. Webster, agricultural gypsum, and two combined treatments—along with a control. Stem samples were collected and processed using standard methods in wood anatomy. Quantitative anatomical traits of vessel elements were measured, alongside evaluations of their functionality. Plants treated exclusively with agricultural gypsum or polyethylene film showed localized anatomical changes, with no evident effects on xylem functionality. In contrast, treatment with Urochloa decumbens alone induced more pronounced anatomical modifications, which affected xylem functionality. The most substantial anatomical and functional changes were observed in the combined treatments (gypsum + polyethylene film or U. decumbens), which enhanced characteristics associated with both hydraulic efficiency and hydraulic safety. Overall, these findings highlight the remarkable anatomical plasticity of coffee xylem in response to soil management practices, suggesting that integrated agronomic approaches may promote the development of vascular systems better adapted to water-limited conditions. Ultimately, this study emphasizes the role of agronomic strategies in enhancing water use efficiency in C. arabica cultivation.
