Hydroponic experiment was conducted to study the effect of peach seedlings (Prunus davidiana) grown in nutrient solution with different Iron (Fe) concentration. The results showed that Fe deficiency could inhibit growth of peach seedlings, the roots and shoots biomass of peach in Fe-free treatment was significant lower than that of other treatments, except for the peach seedlings treated with 60 mg/L Fe. The peach grown seedlings in nutrient solution with different Fe concentration, Fe content in roots increased significantly, in stems decreased significantly, in leaves increased significantly, except for the peach treated with 20 and 60 mg/L Fe, there was a marked drop in total Fe content in leaves compared with control. These results indicated that appropriate amount of Fe (Fe concentration was 20 mg/L) could favour the growth of peach seedlings; and excessive Fe (Fe concentration was 60 mg/L) cloud have deleterious effects on peach seedlings. In conclusion, Fe concentration was greater than 0 and less than 60 mg/L, which was suitable for peach growth, especially the peach seedlings treated with 20 mg/L Fe.
