| Research Abstract |
In this study, colony size and the image information of colony medium (color and shapes) of model mould on PDA agar was measured. Results indicated that the germination of mould and colony diameter under moving temperature was predicted by a simple model by using thermal temperature. It was found that there was temperature dependence in image information of colony. Application for postharvest was also performed for Aspergillus rot in apple, and the lesion was also predicted by derived model. Furthermore, it was suggested that fruits and vegetable subjected temporary to cold temperature slows its decay.
