Abstract

A laboratory experiment was conducted to determine allelopathic potential of aqueous extract of canola residues on GERMINATION TRAITS of wheat (Triticum aestivum L.), barley (Hordeum Vulgar L.) and wild radish (Raphanus raphanistrum L.) seeds, a factorial experiment based on a completely randomized design with three replications was conducted at Agricultural Faculty of Hamedan in 2006. Treatments were three kinds of water extract of canola (shoot, root and shoot + root) and five concentrations (0, 25, 50, 75 and 100 percentage) of extracts. Polyethylene glycole (PEG) was used to distinguish between the inhibitory effect of possible allelopathic substances and effects caused by the osmotic potential of the extracts. Aqueous extract of canola showed allelopathic effects on germination and growth traits of radish. The germination percentage, shoot / root ratio, root length and seedling dry weight of radish decreased with increasing concentration of canola residue. Root length and seedling dry weight of radish showed the most sensitive to canola extract. The aqueous extract of root and shoot had the maximum and minimum allelopathic effects respectively. Unlike barley aqueous extract of canola residues did not have any allelopathic effect on wheat, unlike barley. The extract of canola had no effects on germination and growth of barley by decreasing the germination percent, root length and seedling dry weight. Root length and seedling dry weight of barley were very sensitive to canola residue. Different concentrations of PEG had no significant effects on studied GERMINATION TRAITS, therefore inhibitory effects of extracts can be attributed to an allelochemical effect.
