Allelopathic Effect of Aqueous extract of Erythroxylum monogynum Roxb. on Germination and Growth of Solanum lycopersicum Mill. var. PKM-1
Abstract: Seed germination performance is one of the most essential development stages in medicinal and aromatic plants that may be unfavourably affected by the phytochemicals released from other plants in the soil environment. The present research was conducted in the laboratory to study the allelopathic effect of Erythroxylum monogynum Roxb. to the germination and growth parameters of Solanum lycopersicum Mill. var. PKM-1. Various concentrations of leaf and stem aqueous extracts from Erythroxylum monogynum (0 %, 5 %, 10 %, 15 %, 20 % and 25 %) were valued. Results noted that seed germination, plumule length, radicle length, fresh weight and dry weight of S. lycopersicum were notably decreased by leaf and stem extracts compared with control treatments. Roots were greater affected than shoots; leaf extract was more reduced than stem extract. These result revealed that the inhibitory and stimulatory effect potency may be due to the presence of these allelochemicals like phenols, saponins, tannins and sterols etc. , in the aqueous leaf and stem extracts of E. monogynum from the present study.
