摘　　要：以瓜列当种子为试材,采用不同浓度的磷素溶液(1×10^(-4)、3×10^(-4)、5×10^(-4)、7×10^(-4)、9×10^(-4)、1×10^(-5)、3×10^(-5)、5×10^(-5)、7×10^(-5)、9×10^(-5)、1×10^(-6)、3×10^(-6)、5×10^(-6)、7×10^(-6)、9×10^(-6)、1×10^(-7)、3×10^(-7)、5×10^(-7)、7×10^(-7)、9×10^(-7))对预培养的瓜列当种子进行处理,研究了磷素对瓜列当种子发芽率及瓜列当与加工番茄寄生的关系。结果表明:在磷素溶液为1×10^(-4)、9×10^(-4)、1×10^(-5)、3×10^(-5)、1×10^(-6)浓度下瓜列当发芽率较高,对瓜列当发芽有促进作用,在磷素溶液为7×10^(-6)、9×10^(-5)、9×10^(-6)、9×10^(-7)浓度下瓜列当发芽率较低;在1×10^(-5)和9×10^(-5)级别浓度下瓜列当寄生率最低,且差异不显著,能较好的抑制瓜列当的寄生。因此,10^(-5)浓度的磷在促进瓜列当诱杀发芽和减少寄生方面有很好的应用前景。Orabanche aegyptiaca Pers.seed was used as material,the preculture of Orabanche aegyptiaca Pers.seed were conducted with different concentrations of phosphorus solution （1×10-4,3×10-4,5×10-4,7×10-4,9×10-4,1×10-5,3×10-5,5×10-5,7×10-5,9×10-5,1×10-6,3×10-6,5×10-6,7×10-6,9×10-6,1×10-7,3×10-7,5×10-7,7×10-7,9×10-7）,the regulation of phosphorus to Orabanche aegyptaica Pers.seed germination and O.aegyptiaca Pers.-tomato parasitic relationship were studied.The results showed that the concentrations of P solution of 1×10-4,9×10-4,1×10-5,3×10-5,1×10-6 level had high germination rates and the obvious stimulative actions to Orabanche aegyptaica Pers.seed,when the concentrations of P solution of 7×10-6,9×10-5,9×10-6,9×10-7 level,the germination rate was low,when the concentrations of P solution of 1×10-5 and 9×10-5 level,the germination rate was the lowest,they could generate inhibitation in parasitism.It was concluded that the concentrations of P solution of 10-5 had very good application prospect in promoting trap killing and germination of Orabanche aegyptaica as well as reducing the parasitism rate.
