The results indicated that inoculation with AM fungi notably increased the dry matter, P content, and P absorption rate of P.trifoliata. The contribution of mycorrhiza, P uptake by plant and AM fungi, and the contribution of AM fungi in P uptake by P. trifoliata increased greatly with increasing Al-P level in the medium. Inoculation with AM fungi greatly increased the excretion of phosphatase, especially acid- and neutral phosphatase, from plant root and hyphae, but the excretion amount decreased with increasing Al-P level. The contribution of the fungi in P uptake by P. trifoliata was significantly positively correlated with the amounts of acid-, neutral-, alkaline-, and total phosphatase. %K 枳实生苗 %K 丛枝菌根 %K 难溶性磷酸盐 %K 磷酸酶 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=90BA3D13E7F3BC869AC96FB3DA594E3FE34FBF7B8BC0E591&jid=42FEDDFE54F8BCD9D5FD1926ABDD7722&aid=8E7149DC297AFBFE95C832FA041232E1&yid=67289AFF6305E306&vid=2A8D03AD8076A2E3&iid=F3090AE9B60B7ED1&sid=1FD2ABFFF43897E1&eid=164E897218915EDC&journal_id=1001-9332&journal_name=应用生态学报&referenced_num=0&reference_num=25
