ALLELOPATHIC EFFECT OF BLACK POPLAR (POPULUS NIGRA L.) ON CULTIVATED PLANT
Musharaf Khan
Abstract
The study was conducted to search inhibitory outcome of Black Poplar (Populus nigra L.) leaves on Corn (Zea mays L.) in 2016. The allelopathic influence of aqueous extracts on fresh and dry weight, seedling growth and germination were analyze. It was eminent that 20g aqueous extract of leaves and 72hr treatment presented inhibition on germination, fresh and dry weight and radical length as compare to control. The significant effects of concentration was found on germination (F=2.3717), plumule length (F=32.457), radical length (F=180.215) and fresh weight (F=5.7228) between group. While concentration within group was found in fresh weight (F=39.3202) and dry weight (F=29.8534). The inhibition was increased proportionally with increasing concentration and time duration. With time increasing, germination improved with concentration except 20g at 48 hr. The experiments pointed out that extract have chemicals which limited the germination and production.
