中文摘要 | 硃砂根(Ardisia crenata Sims)之基腐病於1997年在南投地區首次發現,其根冠部及莖基部發現皮層有腐爛、環剝,最後會導致植株萎凋死亡的情形。經切片觀察及組織分離發現病原菌為Fusarium solani Mart.。將純培養病原菌的孢子接種於硃砂根的地基部,可產生與自然界相同的病徵。自人工接種發病株上亦可分離到與接種相同的病原菌。由實驗結果得知本病原菌的侵入與傷口的存在有相關。施用貝芬替灌注莖基部受感染的傷口,於發病初期可以有效地防止本病的發生。 |
英文摘要 | Foot rot of Ardisia crenata Sims caused by Fusarium solani Mart. was first observed in Nantou in 1997. Diseased plants showed basal stem rot, root crown rot, and wilting, and subsequently died. Fusarium solani has been isolated from infested tissues. The disease was reproduced in the greenhouse by inoculation of lower stems with conidial suspension of the fungus. The pathogen was reisolated from inoculated plants to complete the pathogenicity test. Results from inoculation experiments indicated that wounds in the host stem crown can promote disease development. Application of Carbendazim on incipiently infested lower stems was effective for control of the disease. |
