摘要
摘要在温室条件下，用枯丝核菌(Rhizoctonia solani k hn)和枯丝核菌(Fusarium solani, Mart.)混合接种了关节四环菌(Vahl)。Sacc。与单纯接种两种病原菌中的一种相比，可引起显著的萎蔫和根腐病。根和茎感染导致植物生长显著下降。根系总长度减少36 ~ 43%，茎高减少28 ~ 39%。一种病原菌接种植株较对照植株或两种病原菌接种植株短。在接种62天后，被混合病原菌侵染的植物的疾病严重程度等级也高于单独侵染任何一种病原菌的植物。茄蚜和茄蚜具有协同作用，可引起柽柳幼苗严重的枯枯和根腐病。
Effect of interaction between Fusarium solani and Rhizoctonia solani on damping-off and root rot disease of Tetraclinis articulata seedlings
Abstract In the greenhouse, mixed inoculation of Tetraclinis articulata (Vahl) Mast.) with Rhizoctonia solani Kühn and Fusarium solani (Mart.) Sacc. caused remarkable damping-off and root rot compared to simple inoculation with one of the two pathogens. Root and stem infections caused significant reduction in plant growth. Root system total length was reduced by 36 to 43% and shoot height losses by 28 to 39%. Plants inoculated by one pathogen were shorter than control plants or inoculated plants by both pathogens. Disease severity ratings for plants infested with the pathogens mixture also were greater than with either pathogen alone up to 62 days post-inoculation. R. solani and F. solani interact synergistically, causing severe damping-off and root rot in T. articulata seedlings.
