中文摘要 | 由臺灣全省百合栽培地所採集之罹病植株,共分離得 26 株疫病菌。經鑑定所有菌株均為 Phytophthora parasitica。將疫病菌培養於小米粒培養基上,並以土投菌法壤投菌法進行病原性測定,接種量為每盆缽 1 克,發現除 2 株菌外,其餘 24 株均具病原性。以前述人工接種抗病測定方法,檢視商業化栽培百合品種,結果顯示,受測之東方型百合均為感病品種。亞洲型則視品種而定約 50% 品種具抗病性。受測鐵砲百合具抗病性。 |
英文摘要 | In Taiwan, 26 isolates of Phytophthora parasitica were isolated from diseased tissues of field-growing lily. By the use of soil amendment artificial inoculation all the isolates caused stem rot on lily in pathogenicity tests, except two isolates. Phytophthora inocu- lum was prepared by growing the fungus in millet seed and water (1:1) medium for 14 days, and then added the inoculum into the planting mix at a rate of lg/pot. Reac- tions between a commercial variety of lily and phytophthora were tested by this method. Oriental lilies tested susceptible to the pathogen. However, half of Asiatic lily varieties showed resistance to the pathogen. Easter lily is also resistant to Phytophthora. |
