Plant Growth Regulating Activity of Coumarin Based Derivatives
Fauzia Anjum Chattha
Abstract
The present work reports the plant growth regulating activity of coumarin derivatives. A series of coumarin was prepared by reacting phenols with malic acid and diethyl acetoacetate. Compounds were tested for seed germination inhibitory activity using wheat and sorghum seeds along with effects on seedling early growth for 5-days. Some of the compounds had potential seed germination inhibition activity and exhibited reductions in shoot growth and root growth of developing young seedlings compared with that of untreated or control. All compounds exhibited 60-90% inhibitions in seed germination. Shoot and root exhibited 40-80 % reduction in growth at different concentrations.
