Abstract:

Crop plants release biochemicals into surrounding environment that help in obtaining maximum yield of crop by acting as bioherbicide at high concentration and plant growth hormone at low concentration. Therefore, this study was planned at the Department of Agronomy in Weed Science Laboratory, University of Agriculture Faisalabad during Winter season of 2018 to evaluate the hermetic effects of Cinnamomum verum (Dalchini) on vegetable crop radish (Raphanus sativus L.) and determination and quantification phenolic compound present in aqueous extract of bark of C. verum. The experiments were laid out under completely randomized design with three replications. The aqueous extracts of C. verum was used on radish seeds at different concentrations (2.5%, 5%, 10%, 20%, 40% and 80%). Data regarding seed germination and seedling growth (shoot length, root length, shoot fresh weight, root dry weigh) of radish were recorded following standard procedures. Results of our study revealed that the higher concentration acted as bioherbicide and exhibited inhibitory effects on R. sativus while the low concentration it showed hermetic effect and promoted the seedling growth. Among different phenolic compound (syringic acid, p-crumeic, ferulic acid, quercetion and gallic acid) were determined in aqueous extract of bark of C. verum, maximum quercetion (12.3%) and minimum syringic acid (0.60%). It was concluded from this study that aqueous extract of C. verum can be used as bioherbicide at higher concentration to control weed while at low concentration as plant growth regulator.
