摘要

Postharvest disease management is one of the key challenges in commercial mango supply chains. Comprehensive investigations were made regarding the impact of geographic locality on postharvest disease development and other quality parameters in 'Sindhri' and 'Samar Bahisht (S.B.) Chaunsa' mangoes under ambient (33±1°C; 55-60% RH) and low temperature storage/simulated shipping (12±1°C; 80-85% RH) conditions (28 or 35 days storage for 'Sindhri' and 21 or 28 days for 'S.B. Chaunsa'). Physiologicallymature (days from fruit set were 95-100 and 110-115 for 'Sindhri' and 'S.B Chaunsa', respectively) 'Sindhri' and 'S.B. Chaunsa' fruits were harvested from five geographic localities and subjected to ambient and simulated shipping conditions. Under ambient conditions, no disease incidence was observed till fruit eating stage in 'Sindhri'. However, in 'S.B. Chaunsa', significant variation in different localities was observed with respect to disease incidence. Maximum and at par disease was exhibited by the fruit collected from district Vehari and Khanewal in 'S.B. Chaunsa'. Under simulated shipping conditions, disease development varied significantly with respect to different locations and storage durations. In 'Sindhri', fruit of M. Garh, while, 'S.B.Chaunsa' fruit of districts R.Y. Khan, M. Garh and Khanewal showed higher disease incidence. Fruit peel colour development was significantly reduced as storage days increased. Fruit firmness, skin shriveling, fresh weight loss, dry matter, biochemical and organoleptic attributes also varied significantly among the fruit sourced from different orchards of different localities. Analysis of N contents in leaves and fruit peel revealed that N contents of leaf and peel were positively correlated with diseaseseverity in mango. Botryodiplodia spp., Phomopsis mangiferae, Alternaria alternata, Colletotrichum gloeosporioides were the pathogens isolated from fruits of all locations; however, the prevalence frequency varied with the geographic localities. In conclusion, the production locality, cultivar and nutrition (nitrogen content of fruit peel) had significant effect on fruit quality out-turn at ripe stage in terms of disease development so area specific disease management system needs to be implemented forbetter quality at retail.

Chaunsa'水果从五个地理地区收获并进行环境和模拟运输条件。在环境条件下，在'Sindhri'中没有观察到果实饮食阶段的疾病发病率。但是，在's.b. Chaunsa'，观察到不同地区的显着变化，观察到疾病发病率。在S.B中的地区vehari和Khanewal收集的水果展出了最大和判决疾病。 Chaunsa'。根据模拟的送货条件，疾病发展在不同地点和储存持续时间内显着变化。在'Sindhri'，M. Garh的果实，而“S.B.Chaunsa”区的水果R.Y。 Khan，M. Garh和Khanewal表现出更高的疾病发病率。随着储存日增加，果皮果皮显着显着减少。果实萎缩，皮肤萎缩，新减肥，干物质，生物化学和感官的属性在不同地区不同果园的水果中也有显着变化。叶片和果皮中的N内容物的分析显示，叶片和剥离的N含量与芒果的不良性呈正相关。 Botryodiplodia spp。，phomopsis mangiferae，alterararia alternata，colletotrichum gleoosporioides是从所有位置的果实中分离的病原体;然而，流行频率随着地理位置而变化。总之，生产局部，品种和果皮的氮含量）对疾病发展方面成熟阶段的水果质量掉转弯的显着影响，因此特定的疾病管理系统需要在零售业的质量彻底实施。
