摘要
Post-harvest diseases represent a serious problem for citriculture, reducing fruit quality and crop yield. This work aimed to characterize the post-harvest injuries of oranges 'Pêra', 'Lima' and 'Natal' and tangor 'Murcott', during handling in the packinghouse. Samples of one hundred fruits were collected on arrival at the packinghouse, before culling and in the pallet, after hand packing into wood boxes. The fruits were individualized and submitted to humid chambers for 24 hours. Fruits were incubated for 20 days at 25oC and 85% of relative humidity. The incidence of diseases was assessed visually after the removal of the humid chamber and every three days. Fungal pathogenicity was confirmed by fungal inoculation in healthy fruits. Post-harvest disease incidence was similar in different phases of handling system for varieties Lima and Natal. For Pêra and tangor 'Murcott' disease incidence was lower on arrival at the packinghouse compared to other handling phases. Green mold was the most frequent disease in all varieties. Other important diseases were anthracnose (Colletotrichum gloeosporioides), stem-end rots (Lasiodiplodia theobromae and Phomopsis citri), and sour rot (Geotrichum candidum).

收获后的病是一个严重的问题citriculture，降低果实品质和产量的影响。这项工作的目的是描述橙子“佩拉”的收获后的伤害，“利马”和“新生”和tangor“默科特”，处理在屠宰过程中。中百水果样品收集抵达屠宰，宰杀前和托盘，到手后包装成木箱子。水果是个性化，并提交潮湿室24小时。水果孵育20天，在25℃和相对湿度为85％。疾病的发生率在除去湿润室的和每三天后视觉评估。真菌致病性真菌接种于健康的水果证实。收获后的发病率是在处理系统的品种利马和纳塔尔不同阶段相似。对于佩拉和tangor“默科特病发病率较低的到达屠宰相比其他处理阶段。绿霉是最常见的疾病中的所有品种。其他重要疾病是炭疽病（炭疽病菌），干式腐烂（Lasiodiplodia theobromae和拟茎点霉螨）和腐酸（白地霉）。
