Abstract

接種後調查 43 品種檬果果實之田間罹病率，發現品種間之罹病度差異頗大，East Indian 及 Golek 之罹病度最高，分別為 67.65% 及 65.97%；其次為愛文(Irwin) 及 Kaves，罹病度分別為 51.59% 及 50 %，而 White、Tong、Dam、Dasheri、1-4、Thailand 、TL-42、Red、Tuong、Ok Rong、圭寧及 St. Julian 之罹病度均甚低，均不超過 5 %。 Field survey of disease ratios on fruit after an artificial inoculation with Colletotrichum gloeosporioides Penzig for 463 mango varieties showed that the most susceptible ones were East Indian and Golek, with disease ratios of 67.65 and 65.97% , respectively. Irwin and Kaves were less susceptible, with the disease ratios near 50%. The resistant ones, with disease ratios less than 5% were White, Tong Dam , Dasheri, 1-4, Thailand , Tl-12, Red, Tuong, Ok Rong, "Kwei Nin", and St. Julian.
