摘要
豆科槐属多年生植物越南槐(Sophorɑtonkinensis Gagnep.)是我国传统中药材山豆根的基源植物,药用其干燥根及根茎,具有清热解毒、消肿利咽的功效,在历版《中华人民共和国药典》中均有收载[1]。广西是山豆根药材的道地产区[2],近年来随着山豆根市场需求的日益增大,越南槐在广西的种植面积由最初的60多公顷扩增至600多公顷。
The pathogen causing round leaf spot of Sophora tonkinensis(Lour.)was identified by Koch’s postulates,morphological characteristics and combined gene sequences analysis on ITS,TUB,and ACT.The results showed that morphological characteristics of a pathogenic representative isolate SDG-1 was similar to that of Didymella glomerata.The isolate SDG-1 was clustered into one clade in phylogenetic tree with D.glomerata.Taken together,these results indicated that the round leaf spot of S.tonkinensis was caused by D.glomerata.This is the first report of a round leaf spot on S.tonkinensis was identified as D.glomerata.
