Abstract

The growth of Valsa ceratosperma (Tode:Fr.) Maire was analyzed under axenic conditions at several temperatures. An isolate obtained from cankers on trunks of Eucalyptus grandis was inoculated on Petri dishes with PDA medium with plugs of mycelium-agar and incubated under temperatures of 10, 15, 20, 25, 30, 35 and 40 ºC. The growth was evaluated based on linear growth rate of colony (mm/day). The development of V. ceratosperma occurred in the 15 to 35 °C range and the higher rate was verified at 30 °C.
