Laboratory experiment to test Papaver pavoninum Fisch. and C. A. Mey. allelophathic effect against test species maize and brassica

Papaver pavoninum Fisch. and C.A. Mey. (family Papaveraceae) was tested for its allelopathic effects on Maize and Brassica. The aqueous extracts from whole plant, litter and mulches in various experiments, invariably affected the germination, plumule growth, radical growth, Number of seminal roots and fresh and dry weight of both the test species. Phytotoxicity of extracts depended upon concentratin and soaking duration. Generally 48 hour extracts were inhibitorier. Hot water extract was inhibitorier than cold extracts. Added litter and mulching experiments also proved inhibitory, suggesting that Papaver pavoninum has strong allelopathic potential at least against the test species.
