Differences in photosynthesis and carbon-water utilization efficiency among different coffee species in a tropical island of China

This study examined the differences in rhizosphere soil physicochemical properties, agronomic traits, and photosynthetic characteristics of three different coffee species planted at the same location, along with their interspecies interactions to clarify the photosynthetic physiology and carbon-water coupling characteristics of each species, and identified key regulatory factors that influence carbon-water utilization efficiency.

本研究探讨了在同一地点种植的三种不同咖啡物种的根际土壤物理化学性质、农艺特性和光合作用特征之间的差异，以及它们之间的种间相互作用，以阐明每种物种的光合生理和碳-水耦合特性，并确定了影响碳-水利用效率的关键调控因子。
