| 摘 要： | 用不同浓度茶多酚对稻瘟病菌进行抑菌和抑菌机理研究。结果表明,不同浓度的茶多酚对稻瘟病菌菌丝生长和分生孢子萌发具有很强的抑制作用。随着茶多酚浓度的增加,其抑制作用增强,其中5.00 mg/mL和10.00 mg/mL抑制效果最好,其抑制率高达100%,且分生孢子畸形,细胞破裂,原生质外溢。其作用机理主要是破坏菌体的细胞膜结构,抑制CAT、POD酶活,使其丧失细胞膜的屏障和酶系的保护功能,最终导致菌体生长受到抑制或死亡。

| Abstract: | The inhibitive effect of tea-polyphenols(TP) on Pyricularia oryzae at different concentrations and the inhibitive mechanism were studied.The results showed that TP had strong inhibition on hytha growth and conidia germination.With the increasing of TP concentration,the inhibition was increased.The inhibitive efficiency at the concentrations of 5.00 mg/mL and 10.00 mg/mL was the highest,and the inhibitive ratio achieved 100%.The conidia distorted,the cell burst,and the protoplasm overflowed in this condition... |
