摘　　要：为给果树生产提供理论依据,采用土培试验法研究了锰毒害对葡萄植株体内Mn、Ca、Mg、Fe、Cu和Zn含量的影响。结果表明,锰毒害使2个葡萄植株体内各部位Mn含量明显升高,各部位有差异,在金手指中为根>叶片>茎,康拜尔为叶片>根>茎。从整体上看,高锰处理增加了葡萄金手指根茎叶中Mg、Zn以及叶中Cu的含量,降低了根茎叶中Ca、Fe以及根中Cu的含量;增加了康拜尔根茎叶中Mg、Ca以及叶中Cu和根中Zn的含量,降低了根茎叶中Fe及根中Cu的含量。To provide the theoretical basis for the fruit production, a soil culture experiment was conducted to study the effects of Mn toxicity on the contents of Mn, Ca, Mg, Fe, Cu and Zn in different parts of grape plants. The results showed that the Mn contents in different parts of grape plants significantly increased under the condition of Mn toxicity, and the Mn contents varied in different parts of the two varieties, the Mn accumulation in Jinshouzhi was in the sequence of root^leaf~ stem, and in Kangbaier was in the sequence of leaf〉 root~ stem. In general, high Mn stress increased the content of Mg and Zn in root, stem and leave, as well as the Cu content in leaf of Jinshouzhi grape, but decreased the content of Ca,Fe in root, stem and leave, as well as the Cu content in root; while the content of Mg and Ca raised in different parts of the Kangbaier grape, as well as the Cu content in leaf and Zn content in root, but decreased the content of Fe in root, stem and leave, and Cu content in root under high Mn stress.
