摘要： 以缺铁平邑甜茶(M.hupehensis Rehd)为试材，用富铁苹果发酵液进行恢复试验。结果表明：对一年生平邑甜茶幼苗，T3处理（稀释300倍发酵液+FeSO4）较T1处理（去离子水对照）明显提高了平邑甜茶幼苗CAT、POD的活性和MDA、可溶性糖含量，且T2处理（稀释100倍发酵液+FeSO4）比T4处理（稀释500倍发酵液+FeSO4）作用明显；对于三年生缺铁苹果树来说，A3（发酵液+ FeSO4）处理较A1（浇去离子水对照）、A2（FeSO4 溶液）处理明显提高了CAT、POD的活性和MDA、可溶性糖的含量。 总体上，稀释300倍发酵液+FeSO4效果最好。

Abstract: Malus hupehensis seedlings were cultured in iron deficiency Sand,then watered the iron-rich apple broth to recover the iron-deficiency phenomenon.The results showed that:T3 treatment (300-fold diluted broth + FeSO4) increased activities of CAT, POD and content of MDA,soluble sugar of Malus hupehensis seedlings significantly.At the same time, the effect of T2 (diluted 100-fold broth + FeSO4) was better than T4 (diluted 500-fold fermentation of Liquid + FeSO4). For three-years iron-deficiency apple, A3 (broth + FeSO4) increased the activities of CAT, POD and content of MDA,soluble sugar.As a whole, T3 treatment (300-fold diluted broth + FeSO4) is the best treatment for both iron-deficiency seeding and three-years iron-deficiency apple.
