Influence of Decenylsuccinic Acid on Water Permeability of Plant Cells 1

O. Y. Lee, Ed. J. Stadelmann and C. J. Weiser

a Department of Horticultural Science, University of Minnesota, St. Paul, Minnesota 55101

Decenylsuccinic acid altered permeability to water of epidermal cells of bulb scales of Allium cepa and of the leaf midrib of Rhoeo discolor. Water permeability, as determined by deplasmolysis time measurements, was related to the dose of undissociated decenylsuccinic acid (mM undissociated decenylsuccinic acid x minute). No relationship was found between permeability and total dose of decenylsuccinic acid, or dose of dissociated decenylsuccinic acid, suggesting that the undissociated molecule was the active factor in permeability changes and injury.

At doses which did not damage cells (0.0008 to 0.6 [mM of the undissociated molecule x minute]) decenylsuccinic acid decreased water permeability. At higher doses (e.g., 4 to 8 [mM x minute]) injury to cells was common and decenylsuccinic acid increased permeability. Doses above the 10 to 20 (mM x minute) range were generally lethal. The plasmolysis form of uninjured cells was altered and protoplasmic swelling occasionally was observed. The dose-dependent reversal of water permeability changes (decreased to increased permeability) may reflect decenylsuccinic acid-induced changes in membrane structure. Reported effects of decenylsuccinic acid on temperature dependence of permeability and frost resistance were not verified.
