Abstract

California papaya is climacteric fruit with short shelf-life due to quickly decrease of fruit qualities. Starch degradation into sugars during fruit ripening makes its tissues are susceptible to diseases. Applications of fruit coating with chitosan and low temperature storage are expected to increase its fruit shelf-life and supress the fungal growth of anthracnose (Colletotrichum gloeosporioides). This research objectives were to study the effects of chitosan, storage temperatures, and their interactions to the growth of anthracnose in-vitro and in-vivo in California papaya fruits. Two parallel in-vitro and in-vivo experiments were conducted in a completely randomized design of 3 x 2 factorial design. The first factor was chitosan (0; 1.25; 2.50%), the second one was storage temperatures (27-28 °C and 16-18 °C). In in-vitro, observations were made on PDA substrate embedded with chitosans in petri dishes, and inoculated with anthracnose. In in-vivo, observations were made on chitosan-coated papaya fruits inoculated with anthracnose. The results showed that chitosan applied in-vitro supressed totally the fungal growth, but was ineffective in-vivo, low storage temperature 16-18 °C decreased significantly the fungal growth in-vitro by 33.98% and reduced disease severeness in-vivo by 50.02%, and the two factors were interacted in supressing the fungal growth.
