RESUMO
Several radioactive analogues of abscisic acid have been tested for their growth-inhibitory effects and their metabolism in excised embryonic axes of Phaseolus vulgaris. The compounds tested were the methyl and ethyl esters of 2-14C-abscisic acid and the cis- and trans-1′,4′-diols of 2-14C-abscisic acid. All four compounds cause less growth inhibition than abscisic acid, and all four compounds are converted to abscisic acid in the axes at rates which are sufficient to account for most, if not all, of the observed growth-inhibitory activity. None of the four compounds is metabolized to the extent that abscisic acid is metabolized in the axes, suggesting that the structural requirements for growth-inhibitory activity and metabolism may be similar.
