Evaluation of allelopathic effects of some fruit tree leaf extracts on emergence and seedling vigour of lathyrus var. biol-212

Due to non-availability of any information on allelopathic affects of Guava, Lemon, Mango and Papaya leaf extracts on emergence and seedling vigour of Lathyrus Var. Biol-212, a pot culture study was conducted. The extracts were prepared by dipping the fresh leaves of these fruit trees in distilled water in the ratio of 1: 10 w/v (plant material: Water). Lathyrus seeds were soaked in extracts and emergence and seedling vigour were recorded. Different extracts produced significant allelopathic effects. Lemon and papaya leaf extracts produced no inhibitory allelopathic effects. Guava and Mango leaf extracts were identified as harmful extracts.
