Abstract

The present experimental work was focused out to determine phytochemicals of two medicinal laticifers Sarcostemma brunonianum and Ficus tsjakela and to check the allelopathy potential on Sorghum bicolor under in vitro conditions. Allelochemicals are phytocompounds excreted during the process of secondary metabolism. Chemical components may occur in leaves, stem, root, latex, rhizomes, flowers, fruits, seeds and even in pollen grains. Plant latex supports defense in milk yielding plant species. The aqueous extract bioassay of the selected plants were done on the plant parts such as stem and root of S. brunonianum and leaf and bark of F. tsjakela. The results indicated that different concentrations of aqueous extract showed different plumule length of Sorgham bicolor under in vitro conditions. To achieve sustainability in agriculture and maintenance of clean and ecofriendly environment, application of allelopathy effect is recommended, thus it provides one of the safest alternatives to weedicidal and herdbicidal problems for future generations. Evaluation results showed that S. brunonianum and F. tsjakela had strong inhibitory effect on germination as well as root and hypocotyls growth of test seeds. Phytochemical screening of selected medicinal plants was also carried out by using standard methods. The extract contained alkaloid, terpenoids, flavonoids, tannins and saponins in different proportions.Keywords: Laticifers, phytochemicals, allelopathy effectCite this ArticleThamaraikani V, Amala DS, Sekar T.
