对千年桐抗枯萎病性状进行研究表明,千年桐是枯萎病的高抗物种。其抗性与其根部表皮细胞和木栓层较厚、单宁和钾含量较高及过氧化氢酶和多元酚氧化酶活性较强有关。以千年桐作砧木,三年桐优株无性系作接穗嫁接的桐林,不仅能保持高度的抗病性,而且生长快、结实早、盛果期长,能达到高产稳产的目的。 Studies on the resistance of A. tunga to Fusarium wilt showed that A. trilobata is a high resistant species to Fusarium wilt. Its resistance and its root epidermal cells and cork layer thick, tannin and potassium content is higher and catalase and polyphenol oxidase activity. With millennium Tong as rootstock, three years of Tong tree clonal scion graft Tong Lin, not only to maintain a high degree of disease resistance, and grow fast, early fruiting, fruiting period, can achieve the purpose of high and stable yield.
