| 摘 要： | 以对苹果粗皮病抗性不同的两个苹果品种富士(感病) 和乔纳金(抗病) 为材料,通过田间采样、室内盆栽模拟,结合组织化学、显微鉴定和X- 射线微区分析,研究了枝条内锰的累积、分布与粗皮病抗性的关系。结果表明,锰在韧皮部的含量高于木质部,感病品种含量高于抗病品种;粗皮病病斑部位存在氧化锰沉淀,韧皮部锰的局部累积和分布与病斑的分布相一致;锰在感病品种的枝条横截面上存在局部累积现象,而在抗病品种上分布较均匀。

| Abstract: | With two apple cultivars of different resistance to internal bark necrosis (IBN) as plant material, field investigation and greenhouse culture were carried out to elucidate the relationship between accumulation and distribution of Mn in apple shoots and resistance to IBN. Investigation revealed higher Mn content in phloem and shoot of sensitive cultivar than those in xylem and shoot of resistant cultivar. Histochemical test, microscopic observation and X ray analysis indicated that manganese oxide deposited in the IBN spot tissue,and the accumulation and distribution of Mn coincided with the IBN spot in phloem. Localized accumulation of Mn was found in the shoot cross section of sensitive cultivar, while a even distribution of Mn was found in resistant cultivar. |
