Abstract: Effect of various concentrations of Citrus reticulata Blanco leaf extract was studied on seed germination and seedling growth of five common home garden food crops viz.Capsicum annum L. (Chilli), Glycine max (L.) Merr.(Soybean), Zea mays L. (Maize), Oryza sativa L. (Rice), and Abelmoschus esculentus (L.) Moench (Lady's finger) in laboratory using Petri dishes with sterilized absorbent cotton.The experiment was conducted under natural light dark cycle with three replicates.The seeds were regularly irrigated with the C. reticulata extracts.Results of the study revealed that the aqueous leaf extract of C. reticulata have significant effect on seed germination and plant growth.The highest inhibitory effect (55%) of leaf extract was reported on seed germination of chilli at 80% extract concentration and the lowest (3.33%) in maize at absolute concentration.The highest inhibitory effect (65.26%) on shoot elongation was recorded in the maize at 80% extract concentration while at this concentration, maximum inhibition (58.52%) on root elongation was registered in soybean.Under pot culture, shoot length in paddy and dry matter accumulation in chilli were inhibited at all concentration.In general higher concentrations had stronger inhibitory effects while in some cases the lower concentration had stimulatory effects.The study also revealed that the inhibitory effect was much pronounced in shoot and root lengths as compared with the germination of the receptor crops.The studies provide the evidence of C. reticulata having allelopathic potential which reduces the germination as well suppresses the growth and development of the test crops.
