Abstract:
Taking American parsley seeds as test material，the effect of the extracts solution of parsley seeds on the mycelium growth，spore formation and spore germination of ?Fusarium oxysporium f.sp. cucumeris were studied using spore germination and spore suspension liquid method，to discuss the allelopathy mechanism.The results showed that the mycelium of Fusarium oxysporium f.sp.cucumerinum was thinner and less forked after treated with three parsley seeds extraction (distilled water, ethanol and acetone).The spore formation and spore germination were allelopathic inhibited differently after treated，the inhibition rates of spore formation were 40.32%，62.26%，60.42%，and the inhibition rates of spore germination were 19.04%，27.28%，28.08%.Through the electron microscopy observation，the structure of membranes of Fusarium oxysporium f.sp.cucumeris，spores were destructed by three parsley seeds extraction treatment，the intracellular structural was disorded and the contents exosmosed.
