Author 'Sailor' (Id 94375 ) : The olive trees on the island of Kerkira, are still different from those in the south of France, their trunks are gnarled, but they are also cracked. With its trunk carved by age and fleece of silver and evergreen, this tree exceeds potentially legendary longevity oak. Unfortunately, it is not possible to know the age of an olive tree with certainty. Dendrochronology can not be used on an olive tree stump. This species does not have growth rings clear and individualized. The age of an individual can therefore only be an estimate based on indirect evidence - diameter, aspect, historical documents.
