竹荪粗提物对香蕉枯萎病菌FocTR4的抑制效果

Inhibitory Effect of Bamboo Fungus Crude Extracts on Banana Fusarium Wilt Pathogen

  • 摘要: 竹荪作为一种重要的药食两用真菌,其抑菌活性也被广泛证实。本研究通过比较香蕉枯萎病菌FocTR4在含有66.7、50.0、40.0 g·L-1竹荪菌盖、菌托和菌柄粗提取物的PDA培养基上的生长情况,研究竹荪提取物对FocTR4的抑制效果。研究发现:各竹荪粗提物对FocTR4的生长均有一定的抑制作用,菌盖粗提物的抑制效果最佳,极显著优于菌托和菌柄;66.7 g·L-1的菌盖粗提取物对FocTR4的抑制率最高,前6 d均高于30%,在第2 d甚至高达41.18%。结果表明:竹荪提取物尤其是菌盖提取物可有效抑制FocTR4的生长,具有用于香蕉枯萎病农业防治的潜质。

     

    Abstract: Bamboo fungus is a popular pharmaceutical and food material. In recent years, its antimicrobial effects were frequently reported. The present study compared the growth of FocTR4 on a PDA medium containing 66.7 g·L-1, 50.0 g·L-1L or 40.0 g·L-1 of the crude extracts (CEs) from pilei, volva and stipes of the fungi to determine the fungal inhibition effect of CEs. The results showed that all CEs inhibited FocTR4 growth with the efficacy declined as the concentration of CE decreased. The inhibition of pileus CE was the strongest and very significantly higher than those of volva and stipe CEs. The volva CE was only slightly better than the stipe CE in that regard. At 66.7 g·L-1, the pileus CE exhibited a higher than 30% inhibition rate in 6 days. The rate peaked on the second day to 41.18%. The CEs of bamboo fungus, especially from the pilei, demonstrated an effective inhibitory effect on FocTR4, suggesting a promising potential of it being used for controlling banana Fusarium wilt.
