| Frost damages in a field experiment of pruning types and systems for the cultivars of Coffea arabica Catuaí and Mundo Novo, were evaluated at Londrina (23º22S, 52º10´W), State of Parana, southern Brazil, during the winter of 1990 and 1994. Pruning types evaluated were esqueletamento (cutting off all plagiotropic branches at 20-30 cm from the orthotropic branch), decote (cutting off the orthotropic branch at 1.5 m and 2.0 m above ground) and recepa (cutting off the orthotropic branch at 0.8 m above ground), performed on all rows and on alternate rows, and on different sections of the plant. Results indicated that frost damage could increase according to the type and height of pruning. The pruning type esqueletamento and prunings at higher levels... |
