Abstract
Germination and early seedling growth bioassays were used to assess the autointoxication and allelopathy potential of Panax notoginseng which served as donors and P.notoginseng,wheat(Triticum aestivum),rape(Brassica campestris)as receptors.The results were as follows:(1)the autointoxication of P.notoginsengappeared some differences in different density,but showed no obvious regularity.The exudates from seed germination of P.notoginsenginhibited seed germination rate,germination index and seedling height of rape;(2)The allelopathic effects of water extract of P.notoginsengdiffered among receptors.The wheat showed different promotion or inhibition which mainly manifested in the seedling fresh weight,seedling dry weight,root fresh weight,root number of wheat growth.The water extract inhibited the germination rate,promoted the seedling fresh weight,seedling dry weight,root fresh weight,root length of rape;(3)The allelopathy and autointoxication of P.notoginseng was obvious,the substances may be an important factor affecting the continuous cropping.
