Abstract

In order to study the mechanisms of berry growth in Vitis vinifera L. we analysed cell division and pericarp enlargement of 6 genotypes showing high variability in berry size (range: 49-90 %. Both, cell number and cell volume were involved in the small-sized berries of the flb mutant producing wild-type-like berries. The differences of berry size observed in other small-sized clones were only due to cell expansion. The data suggest that the variability of berry size in V. vinifera cultivars predominantly results from modification of cell enlargement. Conversely, in wild-type-like berries, the variability of berry size could result from both, cell division and cell enlargement.
