摘要: 以2年生盆栽华红苹果树为试材,研究嫁接辽砧2号中间砧对华红苹果不同部位的矿质元素含量的影响。结果表明,华红苹果树嫁接辽砧2号中间砧后,叶片、新梢、主干、主根和侧根对多数矿质元素的吸收和利用能力均有不同程度的增加;同一种矿质元素在不同部位的含量不同,其中主根中Fe元素含量高于其他3个部位,其余各矿质元素含量均以叶片中最高;同一矿质元素在不同径级根系的含量明显不同,除了对照的K元素外,所有矿质元素均在d≤0.5 mm根径级的毛细根系内含量最高。

Abstract: This experiment took biennial potted Huahong apple as test material to study the effects of grafting of intermediate stock Liaozhen No.2 on the mineral elements contents in different parts of Huahong apple tree. The results showed that after grafting of intermediate stock Liaozhen No.2, the absorption and utilization of mineral elements in leaves, shoots, trunk, trap roots and lateral roots of Huahong apple tree all increased. The content of the same mineral element was distinctly different in different parts. The content of Fe in trap roots was obviously higher than that in other three parts, while the content of other mineral elements were all the highest in leaves. The content of the same mineral element was apparently different in different diameter classes of roots and all mineral element contents showed the highest amount in the roots with d≤0.5 mm, except the K element in the control.
