SummaryWater stressed coffee plants of five genotypes of C. arabica and one of C. canephora were compared with watered controls for their accumulation of proline and quaternary ammonium compounds. These solutes, mainly proline, accumulated in mature leaves under water stress, their concentration being related to the osmotic potential at zero turgor and to the osmotic adjustment either in well watered or droughted plants. Proline accumulated to a greater extent than quaternary ammonium compounds under water stress.
