Efecto de temperaturas supraóptimas sobre el sistema radical, el crecimiento y la absorción y translocación de nutrimentos en café cultivado en solución nutritiva
Coffee seedlings, Coffey arabica cr. Casual, were grown in nutrient solution for a period of six months after germination, in six special containers, with 25 seedlings in each. The temperature of the nutrient solution in the containers ms kept constant at each of the Jbllowing levels: 27, 29, 30,...
