The aim of the research is to find out the effect of long storage against glucose and vitamin C degree and also to find out how many days of the storage whioch can still maintain the glucose and vitamin C degree upon siam orange ( Citrus nobilis var. microcarpa ). It is expected that the research may give any information especially for the seller of siam orange about the effect of long storage against glucose and vitamin C degree and how many days the storage should be performed. The experimet includes 4 treatments and 5 repetilions. The treatment is the length of the storage, namely 0 day ( control ), 5 days, 10 days and 15 days. The observed parameters are glucose, vitamin C degree and fruit weight decrease. The research uses complete Random design, when there is a real difference Duncan test will be used upon significant degree of 5 %. The result of the research indicates that the glucose degree of siam orange upon the storage of 5 and 10 days increases compared to the control. Upon the storage of 15 days the glucose degree decreases compared to the storage of 5 and upon the storage of 5 days does not change compared to the control, but it starts decreasing upon the storage of 10 and 15 days
