- 摘要:
- 以对大豆胞囊线虫表现不同抗性的五寨黑豆(抗)和合丰35(感)为材料,利用乙醇为有机溶剂,提取大豆根内类黄酮化合物,测定类黄酮提取物对大豆胞囊线虫卵的孵化及J2幼虫的杀线活性。结果表明:大豆不同品种根内类黄酮粗提物对大豆胞囊线虫卵的孵化、J2幼虫均有一定的抑制作用。处理24,48和72 h后,五寨黑豆对卵孵化的抑制率比合丰35分别提高12.76%、9.03%和9.37%。处理48 h,合丰35的校正死亡率比五寨黑豆增加7.0%。抗、感品种根内类黄酮提取物对大豆胞囊线虫J2的生理毒性结果表明:抗、感病品种根内类黄酮提取物均可有效抑制大豆胞囊线虫体内蛋白质和糖的含量。对蛋白质含量的抑制率分别为57.07%和17.60%;对糖含量的抑制率分别为13.75%和8.20%,五寨黑豆显著高于合丰35。
- 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.
