Postharvest physiology and pathology of "Kinnow" mandarin (Citrus reticulata Blanco).

ABSTRACT :

 

Kinnow mandarin is the major commercial citrus cultivar in Pakistan. Its postharvest physiology and pathology were studied in the lab. to better understand the causes of postharvest deterioration and to develop a technology most suitable for extending the shelf-life of fruit. The effect of various postharvest techniques such as antifungal dips, wax-coating and gamma irradiation on the physiological and biochemical parameters was studied during storage. Data on respiration (CO2 production) and ethylene evolution by the fruit and physiochemical changes and fruit decay were collected. Wax-coating not only added shine to the fruit and reduced weight loss but also slowed down the rate of respiration. Gamma irradiation created the problem of skin damage to the fruit at a concn equal to or greater than 1.0 kGy. The pathogens associated with fruit decay were Penicillium digitatum and P. italicum. However, during extended storage, Alternaria citri was observed. Attack by Penicillium spp. was controlled b

y the application of thiabendazole and some antifungal wax emulsions, while black-rot (caused by A. citri) was controlled using an indigenous antifungal product: Antibiotic-F. A process for the preservation of Kinnow was developed and patented. The efficacy of this technique was tested successfully in the field in collaboration with a private sector agency.
