Abstract: Laboratory experiment was conducted in the College of Forestry, SHUATS, Allahabad to determine effect of aqueous leaf extracts of Populus deltoides L. on the germination (%) and seedling growth, biomass and vigour index of Triticum aestivum during 2017-2018. It was noted that aqueous extracts at a concentration of 10, 20 and 40% had inhibitory effect on wheat germination and effect was found significantly higher than control treatment. The maximum germination percentage was observed in wheat variety PBW- 502 whereas the seedling growth, biomass and vigour index was observed maximum in variety PBW-154. The interaction between aqueous extracts concentration and different wheat varieties was found to be non- significant. Therefore it is observed that as the concentration of the poplar leaf extracts increases, its detrimental effects also increases on the wheat varieties.
