Abstract
Taking the ballonflower seeds from different regions as test objects,this paper examined the allelopathy effects of water extracts of walnut leaf,with different mass concentrations(0,0.005,0.01,0.02,0.03 and 0.04 g·mL-1),on seed germination and seedling growth of balloonflower.The results showed that at low concentrations(0.005,0.01,0.02 g·mL-1),walnut leaf aqueous extracts stimulated the rate of seed germination significantly.With the concentration increase of the aqueous extracts,the stimulating effects gradually decreased,and even changed into inhibition.The results of investigation indicated that walnut leaf aqueous extracts enhanced the root length and shoot height of receptor plants,relative electricity conductivity,content of soluble protein and soluble sugar of receptor plants were promoted,and 0.02 g·mL-1 treatment had the biggest allelopathic promotion.Walnut leaf aqueous extract can promote seed germination and seedling growth of balloonflower.
