Abstract: 【OBJECTIVE】Zinc and iron interaction is one of the reasons that cause to the apples physiological disturbance symptoms. Malus Hupehensis Rehd is the most common use rootstock of apple. 【METHOD】We studied the effects of regulation of zinc and iron absorb, translocation, distribute and accumulation in Malus Hupehensis R. under zinc and iron interaction, with solution culture and orthogonal design. 【RESULTS】The results shows that there were significantly effect on the zinc and iron concentration in roots and stems, but it is not significant on leaves under zinc and iron interaction. That’s to say, the interaction of zinc and iron effected accumulation and translocation of zinc and iron on Malus Hupehensis R.’s roots. 【CONCLUSION】The iron and zinc absorb and translocation in roots was promoted under lower iron stress. Under the high iron stress, the zinc and iron hyperaccumulation was promoted, but the zinc translocation to the stem and leaves was inhibited.
