不同嫁接方法对苹果体内铁元素含量及生长发育的影响

Effect of different grafting methods to content of iron and growth on apple trees

59Fe试验结果表明,腹接的方法叶中含铁量显著高于劈接和切接:一年生苗叶片的叶绿素含量和苗的高度、粗度也大于劈接和切接。用腹接取代劈接和切接作为果树高接更新品种的方法对于克服缺铁失绿症、促进更新品种生长具有重要意义。

The test result with59Fe demonstrate:The iron content in leaves by belly grafting is higher than that by cleft grafting and cutting grafting. The content of chlorophyll in leaves and height and diameter of one - year - old tree by belly grafting is larger than cleft grafting and cutting grafting too. It is important to replace with belly grafting to cleft grafting and cutting grafting as a method of top - working to correcting chlorosis and improving growth of new cultivar.
