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。 In order to explore the variation of mineral elements contents in the terminal bud during the process of congenital malformations infected by mango, the changes of mineral elements in the terminal bud after the inoculation with Fusarium mangiferae were determined by using the Kathmandu as test material. The results show that F. mangiferae infection can cause changes in the content of mineral elements in mango. Among them, the content of nitrogen, potassium, iron and manganese increased with the prolongation of inoculation time, and increased greatly, followed by phosphorus, magnesium, boron and zinc, copper and sulfur content did not change significantly with the inoculation time The extension of its content continues to decline.
