Abstract:

Postharvest rots of papaya reduce quality as well as quantity of papaya (Carica papaya L.). Due to firm texture, various microorganisms attack the fruit during ripening stages and cause losses. During the present investigation, effect of various weather factors on the progress of different rots was studied during the year 2019-20. However, storage conditions could not be recorded but, data in terms of normal weather conditions such as monthly average minimum temperature, average maximum temperature and average relative humidity of district Hamirpur were recorded and correlated with disease abundance of different rots viz., anthracnose (Colletotrichum fructicola and C. truncatum), Rhizopus stolonifer, Aspergillus flavus, Fusarium pallidoroseum and Alternaria sp. under study during different months to calculate simple as well as partial correlation coefficients and multiple regression equation. Weather parameters like temperature and relative humidity were found to influence the abundance of these rots to a significant level. Rhizopus rot was positively and significantly correlated with average minimum temperature, Aspergillus rot was positively and significantly correlated while, Fusarium rot was negatively and significantly correlated with average maximum as well as average minimum temperature. Regression equation with weather parameters revealed that these factors could influence the outbreak of rots up to 69.50, 13.00, 45.40, 55.70, 59.20 and 62.30 per cent in case of C. fructicola, C. truncatum, R. stolonifer, A. flavus, F. pallidoroseum and Alternaria sp., respectively.
