苹果不同嫁接方法对^(59)Fe吸收、运输和分配的影响

EFFECT OF DIFFERENT GRAFTING METHODS FOR ABSORPTION, TRANSLOCATION AND DISTRIBUTION OF ^(59) Fe IN APPLE TREES

^(５９)Ｆｅ 试验结果表明，采用腹接叶中含铁量显著高于劈接和切接；一年生苗叶片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。

ABSTRACT The test result with 59 Fe demonstrate that the iron content in leaves by belly grafting is higher than that by cleft grafting and cutting grafting, and the content of chlorophyll in leaves and height and diameter of apple seedling by belly grafting is larger than cleft grafting and cutting grafting too.It is important to replace cleft grafting and cutting grafting with belly grafting as a method of top working to correct chlorosis and improve growth of new cultivar.
