| Abstract: | The ability of a number of plants to grow under conditions ofexperimental flooding has been examined. There was an increasein ethanol production under anaerobic conditions in those specieswhose growth was reduced by flooding. The period of floodinginduced a marked increase in alcohol dehydrogenase activityof the roots of these plants. Plants not adversely affectedby flooding showed no increase in ethanol production and noinduction of alcohol dehydrogenase activity. It is suggestedthat species in which such activation occurs are excluded fromwet areas because of the accumulation of toxic quantities ofethanol. |
