Abstract:

The allelopathic effects of Strychnos nux-vomica L. on seed germination and seedling growth of medicinal plant Solanum trilobatum L. Leaf and bark aqueous extracts of Strychnos nux-vomica at 5, 10, 15, 20 and 25% concentrations were applied to effect their determine on seed germination and seedling growth of test plant under laboratory conditions. Germination and seedling growth tests were performed as CRD (Completely Randomized Design) with 3 replications. The aqueous extracts from leaf and bark had inhibitory effect on seed germination of Solanum trilobatum. The results showed that the extracts brought about considerable inhibition in the germination of Solanum trilobatum seeds and in the growth of its root length and shoot length. The allelopathic effect of leaf and bark extracts of Strychnos nux-vomica decreased the seed germination of Solanum trilobatum with increase in the extracts concentration. The extracts also inhibited the root length, shoot length and dry weight of Solanum trilobatum seedlings with increase in the extracts concentration compared with control treatments. Aqueous extract of leaves shows the higher inhibition while bark shows the minimum effect on Solanum trilobatum. These result revealed that the inhibitory effect potency be due to the presence of the allelochemicals in the extract of Strychnos nux-vomica from the present investigation. Strychnos nux-vomica leaf extracts were more detrimental than stem bark extracts. The evidence obtained could be used in the progress of bioherbicide for future in the field.
