Abstract
This study was carried out to investigate the allelopathic effect of aqueous extracts derived from leaves and stems of Acacia saligna (Labill.) H.L.Wendl. upon two agricultural crops, wheat and canola. Seed germination (%), shoot and root elongation, fresh and dry weight, vigor index and phytotoxicity parameters were estimated. Leaf extract exhibits higher inhibitory effect than stem extract. Wheat seeds were more tolerant to the allelopathic action of A. saligna extracts than canola. Canola germination minimized to 8.33% at concentration 10% of leaf extract but the percent of germination was 60% in the case of stem extract. At 10% leaf extract, 76.67% of wheat seeds germinated; but at 10% stem extract, 93.33% of the seeds were germinated. The other growth parameters as shoot and root length, fresh and dry weight and vigor index also showed continued decrease with the increasing of allelopathic extract concentration. Leaf extract exhibits the stronger allelopathic effect. The phytotoxic effect was stronger on the germination of canola compared with wheat. It reached up to 91.76% inhibition at concentration 10%, but reached up only 23.33% in the case of wheat, respectively
