- ... The effects of varying intensities of light on plants depend on when they occur, even if the total amount of light received is kept constant. We designed an experiment using two clones of robusta coffee (Coffea canephora) intercropped with shelter trees in such a way that allowed us to compare coffee bushes shaded in the morning (SM) with those shaded in the afternoon (SA), and then confronting bo ...

- ... Acclimations to low and high light levels are located in opposite extremes. We examined how the coffee plant (Coffea arabica), which is considered to be shade-demanding although it performs well under full sun exposure, can acclimate to a range of light regimens. We hypothesised that the growth and physiological performance depends on the total amount of light received by the plant per day and on ...

- ... In this study, the combined effects of light and water availability on the functional relationships of the relative growth rate (RGR), leaf chemical composition, construction and maintenance costs, and benefits in terms of payback time for Coffea arabica are presented. Coffee plants were grown for 8 months in 100% or 15% full sunlight and then a four-month water shortage was implemented. Plants gr ...
