Abstract:The quality and storage ability of the four main citrus fruit varieties in hunan province were comprehensively evaluated.'Gongchuan' satsuma mandarin，'Xinnv' ponkan mandarin，'Bingtang' orange，and'Newhall'navel orange fruits were collected from different main production areas in Hunan Province and stored in a ventilated and cold storage environment.Quality parameters i.e.，juice yield and titratable acid（TA），total soluble solid （TSS），and vitamin C （VC）contents and storage parameters i.e.，respiratory intensity，incidence rate，and water loss rate were compared among the four varieties.The titratable acidity in fruits decreased during storage.The incidence and water loss rates of fruits increased gradually with increased storage time，and the TSS and VC contents changed slightly.Correlation analysis revealed the negative correlation of TA with the incidence and water loss rates.Low temperature was suitable for the storage of 'Gongchuan' and 'Xinnv' fruits but not for the long-term storage of rock sugar and Newhall oranges.These findings will help in evaluating the characteristics of the four major citrus varieties and will provide useful guidance for the citrus industry.
