中文摘要 | 山木麻黃和大花紫薇種子幼苗猝倒病於 1996 年在林業試驗所中埔分所溫室首次 發現。罹病山木麻黃和大花紫薇幼苗地際部產生水浸狀黑褐色病斑,使部份或整個幼苗呈腐 爛狀, 最後全株猝倒死亡。 經病組織分離與細胞核染色鑑定後, 證實為立枝絲核菌( Rhizoctonia solani Kuhn )所引起。將病原菌接種到栽培山木麻黃和大花紫薇幼苗的苗床 ,均可產生與自然界發生病害相同的病徵。山木麻黃和大花紫薇接種分離株 B82 與 B83 的 發病率分別為 55-70% 與 50-65%。經分離接種的病組織也可獲得相同的病原菌。 經與已天 菌絲融合群配對,結果顯示為害山木麻黃和大花紫薇的紋枯病菌均屬 AG-4 菌絲融合群。此 兩病原分離株菌絲最適生長溫度介於 20-28 ° C 之間。 當溫度低於 10 ° C 或高於 36 ° C,其菌絲生長緩慢。立枯絲核病菌引起山木麻黃和大花紫薇苗猝倒病為新病害。 |
英文摘要 | Damping-off of Casurina junghuhniana and Lagerstroemia speciosa seedl- ings was first observed in 1996 in the greenhouse of Chungpu Branch Station, Taiwan Forestry Research Institute.The diseased seedlings of C. junghuhniana and L. speciosa were covered with blackish-brown spots at the basal stems, were rotten in part or throughout the entire seedling, and eventually died. Rhizoctonia solani Kuhn was isolated from the diseased tissues and was identified by nuclear staining. Seedlings of the two hosts were transplanted into soil incorporated with R. solani. After one month, disease incidences of C. junghuhniana and L. speciosa were 55-70% and 50-65%, when two R. solani isolates B82 and B83 were inoculated, respectively. The fungus was reisolated from diseased tissues. This is the first report of R. soplani on these two hosts. Optimum temperatures for fungal growth in vitro were 20-28 ° C. Temperatures below 12 ° C or above 36 ° C inhibited fungal growth. |
