ABSTIZACTNormal and misshapen greenhouse-grown tomatoes (n=lOO for each group) were analyzed separately in order to compare their synthetic auxin residue contents. Sharply elongated blossom-ends, "hook-like" and "slice-like" deformations were the auxin-induced shape abnormalities most ojen observed. The greenhouse tomatoes were found to contain only 4-chlorophenoxyacetic acid (4-CPA), but no 2,4-dichlorophenoxyacetic acid (2, or Pnaphtoxyacetic acid (BNOA) residues. Seasonal variations in the mean 4-CPA residues of greenhouse tomatoes were significant ($0.05) through 1994-97. Mean 4-CPA residues of normal and misshapen greenhouse tomatoes were 0.323*0.187 mg kg-' and 0.363kO. 150 mg kg-I, respectively. The dierence was not statistically signifcant (~00.05). The average 4-CPA residue in abnormally shapedfruit is greater than 0.3 mg kg-'. While misshapen fruit always contained residues of at least 0. I mg kg-I, 95% of normal-shapedfruit also contained residues exceeding 0. I mgkg-I.
