摘　　要：分别用大黄素、大黄酚、大黄酸及槲皮素等对植物病原真菌细链格孢、盘多毛孢、栗盘色多隔孢、香石竹单孢锈等菌的产孢数量、菌丝生命活力、菌落产生孢子盘及孢子萌发等进行实验， 发现上述天然产物对上述病原真菌均有显著的抑制作用． 这一发现将对真菌的生理生化研究以及进一步寻找高效、低毒、无公害杀菌剂提供了理论依据．By using emodin,rhein,chrysophanol and quercetin respectively,the authors conducted an experiment on the spore output,hyphal viability and vigor,colony forming sporangia and spore germination of the phytopathogens including Alternaria tenuis,Pestalotia sp , Coryneum kunzei and Uromyces dianthi .The result showed that the natural products of anthraquinones as such had notable repression effects on the phytopathogens.Therefore,this discovery not only contributes to studies on physiological and biological metabolism of fungi,but provides good theoretical bases for the development of effective pesticides with the characteristics of low toxicity,no pollution and wide application.
