Abstract
Compared to Descurainia sophia L.,we studied the effects of root secretion and water extracts of Amaranthus retroflexus L.on Triticum aestivum L.,Brassica campestris L.and Zea mays L.seed germination and growth by using the relay seeding technique.The results showed:(1)the root secretion of Amaranthus retroflexus L.remarkably restrained the growth of crop;(2)Different concentration of Amaranthus retroflexus L.restrained the seed germination.The higher concentration,the stronger effect;(3)Different concentration extracts restrained the growth of crop,except that 0.025 g·mL-1 accelerate the growth of Triticum aestivum L.and Zea mays L..(4)The inhibitory action of Amaranthus retroflexus L.is stronger than that of Descurainia sophia L.The risk assessment proved that Amaranthus retroflexus L.is the plant with higher risks in Shaanxi Province.
