The antifungal test of fungicides was made by using plate mycelium growth inhibition method.[Result] The pathogenic fungi was separated from leaves of Ligusticum chuanxiong Hort. and morphological characters were consistent with that of Colletotrichum gloeosporioides. In addition to chloroisobromine cyanuric acid,the other three fungicides could inhibit the mycelium growth. The growth inhibition rates of 1 000 times Metalaxyl＋mancozeb,zineb,Thiophanate-methyl for the mycelium were 26.8%,22.1%,59.8% respectively after 7 days.[Conclusion] The anthracnose was caused by Colletotrichum gloeosporioides. Ligusticum chuanxiong Hort. was a new record host plant of Colletotrichum gloeosporioides and the best inhibiting fungicide was Thiophanate methyl.展开更多

[Method] Using genomic DNA of Chuanxiong leaf extracted via an improved CTAB method as template, single factor analysis was performed to investigate the impacts of DNA template concentration, Mg2＋ concentration, dNTPs concentration, primer concentration, Taq DNA polymerase concentration on ISSR-PCR amplification and to optimize this system for Ligusticum chuanxiong hort. [Result] The ISSR-PCR amplification（25 μl） suitable for Ligusticum chuanxiong hort. was determined to be composed of 2.5 μl of 10×reaction buffer, 2.1 mmol/L MgCl2, 300 μmol/L dNTPs, 0.4 μmol/L primer, 1.0 U Taq DNA polymerase and 20-40 ng genomic DNA. [Conclusion] Our study laid basis for analyzing the genetic diversity of Ligusticum chuanxiong hort. resources distributed in 17 different areas of China.展开更多
