摘　　要：培养液中缺磷或内生真菌感染对黑麦草地上部生长的影响不显著 ,但二者的交互作用却有着显著影响。随着磷浓度的下降 ,感染内生真菌的黑麦草显示出较强的生长优势 。Lolium perenne infected with Neotyphodium lolii was employed to establish endophyte free (EF) and endophyte infected (EI) populations.They were cultured in Hoagland solutions in greenhouse for the examination of their adaptive response to phosphorus deficiency. The benefits of endophyte infection to the host plants became evident with decreasing phosphorus availability in the solutions. Endophyte infection increased the length of root and the content of phenolic compounds at low phosphorus level.
