Abstract
With cucumber and watermelon as receptors,the allelopathy of aqueous extract from pumpkin root and root-around soil was studied by bioassay methods.The result showed that aqueous extract from pumpkin root and root-around soil exhibited allelopathic promotion or allelopathic inhibition on seed germination rate,germination index,seedling root length,seedling height,seedling dry weight of receptors.When comprehensively evaluating the indices measured,the allelopathy of aqueous extract from pumpkin root and root-around soil displayed concentration effects and receptor differences.Aqueous extract treatments with certain concentrations exhibited allelopathic promotion on seed germination stage,seedling growth stage and the whole development of tested plants,but watermelon was the more sensitive to treatment concentration than cucumber,for cucumber material,promotive potential of 0.02 g/ml aqueous extract from pumpkin root and root-around soil was the highest in each treatment,and the potential decreased or weak allelopathic inhibition exhibited in 0.04 g/ml concentration,while strong allelopathic inhibition exhibited in 0.02 g/ml and 0.04 g/ml aqueous extract from pumpkin root and 0.04 g/ml aqueous extract from pumpkin root-around soil on watermelon material.
