摘　　要：为探讨芒果感染畸形病过程中顶芽内矿质元素含量的变化规律,以凯特芒为试验材料,测定了接种病菌Fusarium mangiferae后顶芽内矿质元素含量的变化。结果表明,F.mangiferae的传染能够引起芒果体内矿质元素含量发生改变。其中,氮、钾、铁和锰的含量随着接种时间的延长不断上升,且上升幅度较大,其次是磷、镁、硼和锌,铜和硫的含量变化不明显,钙随着接种时间的延长其含量不断降低。Changing characteristics of mineral elements contents in Kaite ma ngo in course of infection by Fusarium mangiferae were detected.The results showed that mineral elements contents in the mango were changed after infection of F.mangiferae.Contents of N、K、Fe and Mn were continuously increased by a large margin,and the next were P,Mg,B and Zn.And contents of Cu and S had no obvious changes.While content of Ca was continuously declined at the same condition.
