Abstract
The allelopathic potential of oat (Avena sativa L. extracts was investigated under laboratory conditions The ethyl ether-, acetone-, and water-soluble fractions obtained from the extract of oat shoots inhibited the germination and growth of roots and hypocotyls of lettuce (Lactuca sativa L. The inhibitory activity of the water-soluble fraction was maximum, followed by that of ethyl ether-soluble and acetone-soluble fraction An active principle of the water-soluble fraction was isolated and its structure was determined by spectral data as L-tryptophan L-Tryptophan inhibited the growth of hypocotyls and roots of lettuce seedlings at concentrations greater than 0.03 and 0.1 mM, respectively. These results suggested that L-tryptophan may be an allelochemical which affects the growth or germination of different plant species.
