CAFFEINE CONTENT IN RELATION TO RESISTANCE OF COFFEA ARABICA L TO COFFEE BERRY DISEASE (COLLETOTRICHUM COFFEANUM NOACK)

摘要

Coffee seeds (Coffea arabica) from Ethiopia and Kenya were tested for their resistance to coffee berry disease (CBD, Colletotrichum coffeanum). Reactions of the cultivars under field conditions of both countries were scrutinized. Caffeine contents of the ground dry seeds of reach cultivar were determined with HPLC. In general, coffee selections or cultivars with higher caffeine contents showed a higher field and hypocotyl resistance to CBD.
