Beneficial compounds from coffee leaves
2018Leaves are the leading source of carbon for plant growth and reproduction, and possess a wide range of protection systems against environmental stress. The leaves of the coffee plant, characterized by a high antioxidant potential, have a significant impact on fruit quality, and identifying markers in leaves for plant adaptability to environmental ...

Physiological and Molecular Plant Pathology, 1993
Abstract Lipoxygenase activity was followed in cotyledonary leaves of coffee cultivars resistant and susceptible to the coffee leaf rust ( Hemileia vastatrix ). A rise in lipoxygenase activity was observed during the incompatible interaction, whereas the activity of the enzyme remained fairly constant in the compatible coffee—coffee rust combination.

Diagrammatic Scale for Assessment of Bacterial Blight in Coffee Leaves
Journal of Phytopathology, 2014AbstractDue to the lack of a standardized visual method for assessing bacterial blight (Pseudomonas syringae pv. garcae) in coffee leaves, a diagrammatic scale was developed and validated to quantify the disease. Leaves were collected in crops and nursery with different intensity of symptoms, and the true severity was determined electronically.

Boron Content in Leaves and Coffee Yield from 1990 to 2000 in a Brazilian Coffee Plantation
2002The information related to micronutrients in soils and plants, in Brazil, concentrates more on crop requirements based on practical observations and foliar diagnosis. Boron and zinc are the micronutrients frequently reported as deficient in many crops in Brazil (Malavolta et al, 1991).
