Water relations and drought tolerance
This topic explores how coffee plants manage water, how drought affects their physiology and productivity, and the strategies farmers use to improve resilience in water-limited environments.
Lasting importance
Nutrient uptake and deficiencies
This topic explains how coffee plants absorb nutrients from the soil, the role of each essential nutrient, and how deficiencies manifest in visible symptoms and reduced productivity.
Photosynthesis, shade response, and stress
This topic explores how coffee plants capture energy through photosynthesis, how they respond to shade versus direct sunlight, and how environmental stress affects their growth, yield, and cup quality.
Phenology: flowering, fruit set, maturation
This topic explains the phenological cycle of the coffee plant—how it flowers, sets fruit, and matures—and why these stages are critical for yield, quality, and farm management.
Cherry anatomy: skin, pulp, mucilage, parchment, silverskin, seed
This topic breaks down the structure of the coffee cherry, layer by layer, showing how each part influences processing, flavor development, and the quality of the final cup.
Plant morphology: roots, leaves, flowers, cherries
This topic introduces the main structural features of the coffee plant—its roots, leaves, flowers, and cherries—and explains their roles in growth, reproduction, and quality of the final cup.
