Merr. ‘Harosoy’] and wild onion ( Allium canadense L.) were used to study the effects of four surfactants on cell permeability as measured by loss of intracellular material and on photosynthetic 14 CO 2 fixation. Surfactant-induced alteration in cell permeability could not be related to surfactant-ionogenic class but could be related to reported phytotoxicity. Surfactants that altered cell permeability also inhibited photosynthetic 14 CO 2 fixation, indicating that surfactant effects were not restricted to the outer-cell membrane. Isolated cells from the monocotyledonous wild onion were more susceptible to surfactant-induced alterations in cell permeability than were cells from the dicotyledonous soybean. Efflux of intracellular material was modified by Ca ++ and Mg ++ to a greater extent for soybean than for wild onion. Integrity of the isolated cells, before and after surfactant treatment, was verified by microscopic observation.Read More
