The experimet includes 4 treatmentsand 5 repetilions. The treatment is the length of the storage, namely 0 day ( control ), 5 days, 10 days and 15days. The observed parameters are glucose, vitamin C degree and fruit weight decrease. The research usescomplete Random design, when there is a real difference Duncan test will be used upon significant degree of5 %.
