- Abstract
In the present work plant growth regulating activities of coumarin-3-acetic acid derivatives are reported. A series of coumarin-3-acetic acids were prepared by reacting the phenols with diethyl acetylsuccinate followed by acid hydrolysis. The bioactivity of these compounds were tested on seed germination and seedling growth of wheat and sorghum seeds. Several of these compounds inhibited the seed germination and reduced the shoot and root growth of seedlings than untreated control. All compounds inhibited the shoot and root growth of young seedlings at 1 ppm, however, some stimulated the seedlings growth. At higher concentrations (10 ppm or 100 ppm), seed germination was slightly affected but the shoot and root growth inhibition was more affected. Compounds 2,4,6,7 stimulated the shoot growth but did not effect the root growth.
