WINTER COLD RESISTANCE OF JATROPHA CURCAS L. ONE YEAR AFTER TRANSPLANTING IN OPEN FIELD IN SOUTHERN ITALY
A trial was conducted from May 2009 to the end of March 2010 to test the winter cold resistance of 3 cultivars of Jatropha curcas L. in a location of Southern Italy. Observations were recorded every 15 days and until the end of November 2009 they showed a good vegetation stage. No flowering was observed. Due to the low temperature (-2°C minimum) which occurred in February and March 2010, the plants of all cultivars lost all the leaves and dried completely. At the end of March 2010 all the cultivars showed 100% of mortality and they were easily rooted up.
