Abstract
楊桃炭疽病（病原菌：Colletotrichum gloeosporioides）爲臺灣地區楊桃栽培上最常見的病害。本病之病徵、病原菌形態、病原性及影響病害發生之因子，如溫度、感染源之來源等爲本研究探討的重點。C. gloeosporioides係以分生孢子爲感染源，分生孢子之發芽及附著器形成的最適溫度分別爲16~36C及16~24C。Anthracnose of carambola caused by Colletotrichum gloeosporioides is widespread in Taiwan. The disease symptom, morphology of the causal agent and the factoces in firs affecting the disease incidence such as temperature and inoculum sourelds were surveyed in this study. The optimum temperatures for the conidial germination and appressorial formation were 16~36C and 16~24C, respectively.
