Effect of aqueous leaf extracts of poplar (Populus deltoides L.) on germination and seedling growth of wheat varieties (Triticum aestivum L.)

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.
