GA 1 , GA 8 , GA 17 , GA 19 , GA 20 and GA 29 were identified by combined gas chromatography‐mass spectrometgry (GC‐MS) in immature seeds and pericarp of Lycopersicon esculentum Mill. (tomato). Higher levels of these GAs were present in the seeds than in the pericarp; seeds in addition contained GA 15 , GA 24 , GA 25 , and GA 44 . Fruits of the Lycopersicon pimpinellifolium Mill. mutant I were smaller and contained lower GA 1 concentrations, but higher GA 20 concentrations, than those of mutants III and IV. In contrast, differences in fruit size in L. esculentum due to position on the truss did not correlate with GA 1 concentration in either the pericarp or seeds.
