Fruit ripening of three coffee cultivars at Londrina, PR, southern Brazil
This study was conducted at the Centro Experimental of the Instituto Agronômico do Paraná (IAPAR) at Londrina, PR, Brazil, for the period 1977 to 1978 to evaluate the fruit ripening of three cultivars of Coffea arabica L.: Bourbon-Amarelo, Catuaí-Amarelo, and Mundo Novo. Coffee beans were picked by hand from three trees of each cultivar in every month of the year and then divided according to the maturation grades: pinhead, green, light green, cherry-reddish color or cherry-yellowish color, natural dry, unnatural dry, and those naturally fallen on the ground. Results indicated that for the period evaluated the coffee cultivars were classified as following: Bourbon-Amarelo the earliest maturing, Catuaí-Amarelo the latest maturing, and Mundo Novo the midseason maturing. As a consequence, the best harvest times were June in 1977 and May in 1978 for Bourbon-Amarelo and July for Mundo Novo, respectively. Although Catuaí-Amarelo was classified as a late maturing cultivar, the ripening of fruit was variable and spread over a long period of time after July. Thus, the yield losses by the frost are higher for the cultivar Catuaí than for the others.
