Abstract
The content of mannitol and malate was assayed enzimatically during spring, summer and autumn, in leaves of two species of ash traditionally cultivated in Sicily for the extraction of manna. The results suggest that in these species, under the local field conditions, mannitol has a more relevant role than malate in the response to summer drought.
