An Investigation of the Seasonal Pattern of Mannitol Content in Deciduous and Evergreen Species of the Oleaceae Growing in Northern Sicily

Leaf mannitol content in response to drought

Mannitol is one of the compatible solutes that may accumulate under stress. Oddo et al. (pp. 239-243) show that leaf mannitol content of four deciduous and evergreen Mediterranean tree species differs throughout the seasons. When mannitol does accumulate, its occurrence is negatively correlated to rainfall.
