Characterization of fruit and seed development in wild-type tomato and amiARF5 transgenic lines.

Note: The fruits were from mature fruits of pollinated and emasculated (indicated), approximately corresponding to 45 d after anthesis with pollination and unpollination, respectively. For each line, 15–30 fruits were sampled for statistical analysis. The total number of flowers for evaluation of fruit set rate is indicated (n).
