Abstract

The effects of three biodegradable detergents upon root elongation of Cucumis sativus and Avena sativa was determined. All three detergents inhibit root elongation; the degree of inhibition depends on the brand of detergent and the species tested. Contact of the detergents with a sandy-loam results in reversal of inhibition of root elongation; the degree of reversal varies with detergent and species. However, reversal after 48 hours contact with soil does not appear to be due to degradation by microorganisms. Effects of aeration and of pH on test solutions are discussed.
