对参试的２３个材料，以发病率为依据，通过自然感染和人工接种的方法进行抗病性鉴定。结果表明，在田间自然感病下，未发现高抗和抗病材料，只有７个中抗材料，即意大利酸橙、小红橙、酸柚、枳、摩洛哥酸橙、蚌柑、２５８８宜昌橙；在室内人工接种保持高温高湿条件下，１２个参试品种中１个为感病，１１个为重感。 The 23 materials tested were evaluated for disease resistance by natural infection and artificial inoculation based on the incidence rate. The results showed that in the field of natural disease, no high resistance and resistance to disease-resistant material was found, only seven anti-resistant materials, namely Italian lime, small red orange, sour grapefruit, trifoliate orange, Moroccan lime, clams, 2588 Yichang orange In the indoor artificial inoculation under the conditions of high temperature and high humidity, one of the 12 tested varieties was susceptible and 11 were heavy.
