This paper reports on the study of the beginning termination and duration of the active period of leaf wetness in the coffee. Surface wetness was observed in two plots a vranged in a north-south orientation, on the sides ...
Formacao de ácidos orgánicos, acúcares e lipídeos a partir de acetato C em folhas de cafeeiro
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1980-07)
The acetate 14C metabolism was studied in detached coffee leaves (Coffea arabica L. cv. 'Mundo Novo'). The leaves were incubated in 10 pCi of acetato-1-C and 10 uCi of acetato-12-25C out of Inminosity Incubation was ...
Variación estacional de la reductasa de nitrato en el cafeto
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1980-07)
The sesonal trends of nitrate reductase activily, of NO-3 induced activity of the same enzyme, and of the quotient between them, aRNi/aRNb, known as Nitrate Assimiletion Potential, were investigated. Assays were carried ...
