Coffee is a very important product in the State of Espírito Santo, Brazil, and most of it is planted as unshaded coffee monocultures, with few growers managing shaded coffee agroforestry systems (AFS). To analyze the opportunities and challenges associated with coffee agroforestry management, we conducted 58 semistructured interviews with coffee growers. In addition, we conducted a field investigation that tested production of Coffea canephora with the shade trees Australian Cedar (Toona ciliata), Jequitibá (Cariniana legalis), and Teak (Tectona grandis). Of the 58 interviewed farmers, 64% (37) were satisfied with the AFS. One of the main factors that caused satisfaction was obtaining income from sources other than coffee. Unsatisfied farmers mentioned the competition between shade trees and coffee shrubs. Cedar was the shade tree that grew most and reduced coffee production, while the combination with Jequitibá maintained more stable yields. We conclude that the higher the growth rate of trees, the higher the negative impact on the coffee production in the study areas. |

Four clones of robusta coffee representing drought-tolerant (14 and 120) and drought-sensitive (46 and 109A) genotypes were submitted to a slowly imposed water deficit. Sampling and measurements were performed when predawn leaf water potential (Ψpd) approximately −2.0 and −3.0 MPa was reached. Regardless of the clone evaluated, drought led to sharper decreases in stomatal conductance than in photosynthesis, which was accompanied by significant declines in internal to ambient CO2 concentration ratio. Little or no effect of drought on chlorophyll a fluorescence parameters was observed. Regardless of the stress intensity, starch decreased remarkably. This was not accompanied by significant changes in concentration of soluble sugars, with the exception of clone 120 in which a rise in sucrose and hexose concentrations was found when Ψpd reached −3.0 MPa. At Ψpd = −2.0 MPa, activity of acid invertase increased only in clone 120; at Ψpd = −3.0 MPa, it increased in clones 14, 46 and 120, while activity of sucrose synthase declined, but only in clone 109A. Drought-induced decrease in ADP-glucose pyrophosphorylase activity was found only in clones 14 and 46, irrespective of stress intensity. At Ψpd = −3.0 MPa, maximal extractable and activation state of sucrose-phosphate synthase (SPS) decreased in all clones with the exception of clone 120, in which SPS activity was maintained in parallel to a rising activity of fructose-1,6-bisphosphatase. Changes in SPS activity could neither be explained by the CO2 decrease linked to stomatal closure nor by differences in leaf water status.
