| 摘 要： | 调查了昆明地区引起苹果早期落叶的叶部病害主要种类，结果表明：由轮斑病和斑点落叶病、褐斑病引起的苹果落叶较严重；2次调查中，轮斑病和斑点落叶病的植株发病率均为100％，8月和10月的平均病情指数分别为67．5和72．9；而褐斑病植株发病率相对较低，8月和10月的平均发病率分别为87．81％和44．98％，平均病情指数也由8月的22．3降低至10月的12．8；由褐斑病引起的苹果落叶时间要早于轮斑病和斑点落叶病。 |

| Abstract: | The main species of leaf diseases causing early defoliation of Malus pumila trees in Kunming area were surveyed. The results showed that Macrophoma kuwatsukai, Alternaria mali, Marssonina coronaria diseases were the main causes for Malus pumila tree defoliation. The incidence of both Macrophoma kuwatsukai and Alterna- ria mali was 100% individually by the twice surveys in August and October. Whereas the disease index of these two diseases was 67.5 and 72.9 separately by the two surveys. The incidence of Marssonina coronaria was compar- atively lower, the average incidence rate of which was 87.81% and 44.98% individually in August and October. The disease index dropped from 22.3 in August to 12.8 in October. However, the defoliation of Malus pumila trees caused by Marssonina coronaria happened earlier than that of caused by other two diseases. |
