摘要

摘要影响越南山区球囊花(桔梗)的最主要问题是茎腐病和根腐病。本研究旨在鉴定老蔡省球囊花病原菌枯萎病。通过DNA测序和基于ITS序列的系统发育分析证实了F. solani的身份。在三种半固体培养基(CA、PDA和CDA)中，PDA是最适合茄菌生长发育的培养基。其生长的最佳温度和pH为25 ~ 30℃，最大生长速率为25℃;pH为5.5 ~ 7.0，最大生长速率为6.5。这是越南首次报道引起球囊茎、根腐病的茄蚜。

Molecular characterization of Fusarium solani causing stem and root rot disease of balloon flower (Platycodon grandiflorus) in Viet Nam

Abstract The most significant issue affecting balloon flower (Platycodon grandiflorus) in Vietnam’s mountainous provinces is stem and root rot disease. The purpose of this study was to identify the causal fungus Fusarium solani of balloon flower planted in Lao Cai province. F. solani’s identity was confirmed through DNA sequencing and phylogenetic analyses based on ITS sequences. PDA was the most suitable medium for F. solani growth and development of the three semi-solid media tested (CA, PDA, and CDA). The optimal temperature and pH conditions for its growth ranged from 25-30 °C with a maximum growth rate of 25 °C and pH 5.5-7.0 with a maximum growth rate of 6.5. This is the first report of F. solani causing balloon flower stem and root rot in Vietnam.

期刊介绍： Archives of Phytopathology and Plant Protection publishes original papers and reviews covering all scientific aspects of modern plant protection. Subjects include phytopathological virology, bacteriology, mycology, herbal studies and applied nematology and entomology as well as strategies and tactics of protecting crop plants and stocks of crop products against diseases. The journal provides a permanent forum for discussion of questions relating to the influence of plant protection measures on soil, water and air quality and on the fauna and flora, as well as to their interdependence in ecosystems of cultivated and neighbouring areas.
