Abstract

‘California’ papaya is a relatively new-released papaya cultivar and dominating papaya markets in Indonesia. It has a very short shelf-life with a quickly decrease of fruit qualities. Anthracnose [Colletotrichum gloeosporioides (Penz.) Sacc] is one of its major postharvest disease. Postharvest treatments with a fruit coating of sugar ester blend KD-112 and low storage temperature are common practices in agroindustries other than papaya. This research objectives were to study the effects of fruit coating KD-112 and storage temperatures to the growth of C. gloeosporioides in vitro and in vivo in papaya fruits. Two paralel experiments of in vitro and in vivo were conducted in a completely randomized design of a 3 x 2 factorial design. The first factor was KD-112 (0, 7 and 14%), the second one was storage temperatures [room temperature (27-28 ºC) and cooler one (16-18 ºC)]. In the in vitro experiment, observations were made on a PDA substrat in petri dishes embeded with KD-112, and later inoculated with C. gloeosporioides. At the in vivo experiment, observations were made on papaya fruits inoculated with fungi C. gloeosporioides. The results showed that KD-112 did not significantly decrease the fungal growth of C. gloeosporioides both in vitro and in vivo, low storage temperature of 16-18 °C decreased significantly the fungal growth in vitro by 36.71% and reduced the disease severeness in vivo by 43.75%, but their interaction did not decrease significantly the fungal growth both in vitro and in vivo.
