Abstract
The variation in the cork produced by individual trees (Quercus suber L.) i n three distinct locations, Mora, Alcacer do Sal and Benavente, is characte rized by measurements made during two consecutive harvests of cork in the s ame trees. Particular emphasis is given to the variability in the weight of cork produced by individual trees and its mean caliper for the two strippi ngs in each region. A good linear correlation between the tree circumferenc e after the first stripping and the weight of the cork produced 9 years lat er as well as a poor linear correlation between the first variable and the caliper of the cork produced 9 years later is reported. A cork oak diameter curve is presented for each region, considering their two radial growths: the wood growth, which is cumulative, and the cork growth, which is the 9-y ear growth.
