Figure i. John Baer tomato fruits. The two central fruits were produced 

 by pollination and the two end ones by treating the cut style of an unopened 

 flower bud with 2 per cent indolebutyric acid in lanolin. 



Figure 2. A cross section of a parthenocarpic tomato fruit produced by 

 treating cut style of an unopened flower bud with indolebutyric acid. The 

 locules are well developed, but the ovules have not developed into seeds. The 

 gelatinous material found in normal seeded fruits fills the locules of this 

 parthenocarpic fruit.
