English summary: Fruit maturity shows strong effect on its quality and shelflife. It is more importance for climacteric fruits as persimmon, of which harvesting season last quite short. During the peak time, an abundant supply of fruit makes its commercialization difficult. Therefore, purpose of this study is to determine quality of persimmon fruit cv. Nhanhau harvested at different maturity and their selflife at room temperature. Color of fruit skin was chosen as indicator for their maturity. Fruits were harvested as their skin turn yellow, greenish yellow and green in corresponding with maturity stage of 3, 2 and 1. The results show that the longer fruit stays in the mother tree the higher amount of main chemical content like dry matter, total soluble solid, carotenoid and the lower tannin they have, so quality of their ripen fruits will be better. Beside of that, the yield of more matured fruit is higher (the yield of maturity stage 3 is 3,9% and 11,3% higher than maturity stage 2 and 1). Ripen fruits harvested at maturity stage 3 have the good sensory quality. However, at that maturity their shelflife lasts very short only for 10 days at room temperature. As a result, they could be commercialized at local market or transported for quite short distances; Ripen fruits harvested at maturity stage 2 have the almost the same quality as maturity stage 3 after 10 and 20 days storage at the room temperature. So they could be commercialized at long distance markets or store over peek harvesting season; Although fruits harvested at maturity stage 1 can be last for 30 days at room temperature and their appearance is still possibly acceptable at ripen stage, but taste is not so good. Therefore, they could be used at off-season or for special purpose like fruit decoration.
