摘要
白芷根腐病由菜豆壳球孢引起。该菌在培养中只产生菌丝体和微菌核。菌丝在ＰＤＡ培养基上生长最快，产生的微菌核数量最多；在白芷培养基生长较慢，但形成的微菌核个体最大。菌丝生长的温度为１０～４０℃，最适温度为２５～３５℃，生长的ｐＨ值为３～１２，最适ｐＨ值为５～６。
he pathogen that caused root rot on Angelica dahurica after harvest and its mainCharacteristics were studied.The result showed that the root rot was caused byMacrophomina phaseolina,The fungi only produced mycelia and microsclertia in cultiva-tion and research process. The pathogen can grow best on PDA me(lium and produce mi-crosclerotia greatly, its growth speed was slower on BDA medium comparatively,but thesize of microsclerotia prodticed on BDA was the greatest.For growth of this fungi.therange of temperature was 10～40 ℃, the optium was 25～35 ℃,the pH range and optiumpH value were pH 3～12, pH 5～6,respectively.
