✦ Synopsis

The effect of cis-propenylphosphonic acid (PPOH), a structural analoge of ethylene, on flower wilting and ethylene production was investigated using cut carnation flowers which are very sensitive to ethylene . Wilting (petal in-rolling) of the flowers was delayed by continuously immersing the stems in a 5-20 mM PPOH solution . In addition, the continuous treatment with PPOH markedly reduced autocatalytic ethylene production of the petals accompanying senescence . This reduction of autocatalytic ethylene production was considered responsible for the inhibitory effect of PPOH on flower wilting . The inhibitory activity of trans-propenylphosphonic acid (trans-PPOH), on both flower wilting and the autocatalytic ethylene production accompanying senescence was markedly lower than that of PPOH, suggesting that PPOH action is stereoselective . PPOH may be of interest as a new, water-soluble inhibitor of wilting and autocatalytic ethylene production in cut carnation flowers .
