菊花 흰녹병균의 發生 樣狀, 小生子의 適正 形成溫度, pH 및 品種別 抵抗性 = Degree of Incidences to white rust on Chrysanthemum Effect of Temperature, pH for Sporidium Formation by puccinia horinia and Resistance of Cultivars to Typical Disease

다국어 초록 (Multilingual Abstract)

Deree of incidences to white rust on chrysanthemum, effect of temperature, pH for sporidum formation by puccinia horinia and resistance of cultivars to typical disease were investigsted in the field and laboratory.
1.Degree of Incidences of white rust by puccinia horinia on chrysanthemum were progressed hightly virulence at May.
2.Sporidium formulation were developed at 5∼25℃ and pH 4.0∼8.5 after incubation. Optimum temperature and pH of formulation for sporidium were 20℃ and pH 7.0.
3.When 25 major cultivars were evaluated for their levels of resistance to damping off in the field, 7 cultivars including Weldon were showing high level of resistance and the low level of resistance were Spring Song, Arieta and Dax. The resistance cultivars to black spot were showing 7 including Westland Pink. Showing cultivars of the low level for resistance were Rose Queen and Spring Song. Resistance to brown spot were 8 cultivars including Westland Pink, and the low level for resistance were in other of Harliquine, Park Marble. Showing the resistance level for of micronutrient deficient were 13 cultivars including Westland Pink and Arieta were susceptive of the high level. Cold Resistance of flower were Harliquine and 6 the others. Cultivars, the high level of susceptible were in other of Spring Song, Rose Queen and Salmon.
