Abstract:
Two cultivars with different resistance to Heterodera glycines,Wuzhaiheidou(resistant)and Hefeng 35(susceptible)were selected as materials to extract flavonoids in root by ethanol as organic solvent.The nematicidal activity of flavonoids extraction on the hatchability of cysts and the activity of J2 were determined.The results showed that flavonoids extracted from different varieties could effectively inhibit Heterodera glycines eggs hatched and kill J2.The inhibiting of Wuzhaiheidou flavonoids extraction increased 12.76%,9.03% and 9.37% more than Hefeng 35 when treated for 24,48 and 72 h.Treating 48 h,revised mortality of Hefeng 35 flavonoids extraction on J2 increased 7.0% than Wuzhaiheidou.The results of physiological toxicity of two varieties flavonoids extraction showed that:the flavonoids extraction of resistant and susceptible varieties could inhibite the glucose and protein content of Heterodera glycines.The inhibition of protein content were 57.07% and 17.60%,respectively.The inhibition of glucose content were 13.75% and 8.20%,respectively.
