Fig. 6. Distribution of pericarp nuclei according to their DNA content from 2C to 256C in competition (A) and pruned (B) experiments at basal (CF14b, CF12b) and tip fruit positions (CF14t, CF12t). Data are means of three MG fruits and each measurement is the mean of three replicates per fruit. Vertical bars represent 95 % confidence intervals. + and * indicate significant differences (P < 0·05) between, respectively, the two tomato lines for a given fruit position and the two fruit positions for a given tomato line.
