Physiology of the Coffee Crop

  • Chapter

Abstract

The purpose of this review is to summarise existing information on the physiology of the coffee crop, with emphasis on whole-plant physiology and on those characteristics that influence the yield of beans. Information has been drawn from work in Kenya, which is well known to the author, from published reviews on coffee crop physiology (Huxley, 1970; Cannell, 1975), water relations (Nunes, 1976), eco-physiology (Maestri and Barros, 1977) and flowering (Alvim, 1973; Browning, 1975b; Barros, Maestri and Coons, 1978), and from the more recent literature. Most of the statements made here refer specifically to arabica coffee (Coffea arabica L.) but many will also be true for robusta coffee.
