| 在沙培条件下采用双因素正交设计，单孢子接种、套袋密闭培养方法，探究了在低磷（1 μmol/L）和高磷（400 μmol/L）条件下小麦幼苗根系接种球囊霉属的摩西球囊霉孢子后，对小麦农艺形态、生理指标及干物质累积的影响。
结果表明：在低磷条件下接种摩西球囊霉后，小麦株高比对照增加13%，根系干重增加26%，地上部增加29%，植株干重增加34%；不论高磷还是低磷水平，接种摩西球囊霉后小麦叶片水势均低于对照水平；幼苗根系活力分别比对照提高了196%（1 μmol/L P）和89%（400 μmol/L P），叶绿素含量升高；根系和叶片可溶性蛋白含量均高出对照。因此，小麦和摩西球囊霉真菌能形成较好的共生互惠体系。 |

| In order to investigate the influence of inoculation of Glomus mosseae on the wheat growth under low phosphorus level (1 μmol/L) and high phosphorus level (400 μmol/L), a single spore inoculation method was used, and during training sunbags was used to cover the whole pot in order to avoid the influence caused by other fungi. The wheat was cultvated in sand supplied with Hogland solution containing different P concentration, and wheat seedlings were inoculated with the spore of Glomus mosseae. The results showed that: compared with the uninoculated wheat, the inoculation increasd the height, root dry weight and plant dry weight of wheat seedings. Whether high phosphorus level or low phosphorus level, inoculated with G. mosseae fungi, the water potetial of leaf was lower than that of uninoculation; the root activity was increased by 196% (1 μmol/L P) and 89% (400 μmol/L); and content of chlorophyll was added; and content of soluble protein was increased clearly in root and leaf. Our conclusion was that wheat and G. mosseae fungi could form good symbiont. |
