Table 1.

Morphometric parameters (length, maximum diameter) and weight of the acorns at the different maturation stages (M1 to M9). M9 corresponds to the mature fruit. The data are presented as the mean ± Standard error of six replicates. Different letters indicate a significant difference with p < 0.05 (Tukey test).
