Water relations in coffee. Significance of plant water deficit to growth and yield; a review

The intensive management of the coffee crop requires rational irrigation. Plant parameters such as stomatal closure or freezing point depression of cellular sap are early indicators of plant water deficits. Conversely, the transpiration rate is a very insensitive indicator and cannot be used to determine irrigation requirements. Net photosynthesis is severely affected by small water deficits, a decrease of about 50 being expected from a 92-80 drop in relative turgidity of the leaves. The ratio T/P expresses the relative effect of water stress on transpiration and photosynthesis and therefore is valuable selective parameter for drought resistance and has a great value under the perspective of agricultural economy. Other effects of plant water deficits on respiration, flowering and fruiting processes as well as some of the more important points which deserve further investigation are also discussed
