中文摘要 | 山葵因長期栽植之結果,病害已有日益嚴重的趨勢。自1990到1998年間,於臺灣中、南部等栽培區調查,發現山葵地上部主要真菌病害種類,以Phoma wasabi引起之葉黑斑病(或稱葉斑病);Peronospora alliariae-wasabiae引起之露菌病及Albugo wasabiae引起之白�蚽f等最為普遍;至於由Ersiphe sp.引起之白粉病則僅在簡易溫室設施內及遮蔭較差之區域發生。葉黑斑病全年均可發生,惟夏季(五至六月或雨季)較為嚴重。白�蚽f亦可周年發生,惟在3至5月及9月至11月發生較嚴重,至於高溫期則偶有發生。露菌病主要發生於4至5月間及9至10月間;至於白粉病僅在10月至翌年2月間發生較嚴重,其他時期則少見。在臺灣,上述山葵病害除葉黑斑病曾被記載外,其他均為首次報導;特別是山葵白粉病是世界首次之記載。在測試之山葵品系中,顯示紅梗種(真妻或本地種)對露菌病、白�蚽f與葉黑斑病較青梗種(信玄與臺農一號)感病;相反的,青梗種白粉賡較為感病。 |
英文摘要 | The wasabi (Wasabia japonica) is an important exported economic commodity from Taiwan to Japan. According to a survey for fungal diseases on aboveground parts of wasabi plantings during 1990 to 1998, Phoma leaf spot caused by Phoma wasabiae, white rust caused by Albugo wasabiae, and downy mildew caused by Peronospora alliariae-wasabiae were common fungal disease on wasabi in the central and central-southern counties of Taiwan. On the contrary, powdery mildew incited by Erysiphe sp was only found in greenhouse at Mayfeng (Nan-Tou), and few fields at Ta-pang (Chiayi). Phoma leaf spot of wasabi was observed around whole year. White rust of wasabi was also found in the whole year, but severely occurred in March to May and in September to November. Downy mildew of wasabi was often found in April to May and in September to October. Powdery mildew only occurred in November and this could be the first report of the wasabi diseases in the world (at least in Taiwan and Japan). For susceptibility tests of wasabi cultivars to these fungal pathogens, the results indicated that the cultivar of Sin-shin of wasabi was more resistant to Phoma leaf spot, white rust, and downy mildew than Local variety and 70-I-1 cultivars of wasabi. However, the sin-shin cultivars was more susceptible to powdery mildew than Local variety and 70-I-1 cultivars of wasabi. |
