The changes of dietary liber content in cultivars of Asian pear (Pyrus pyrifolria) fruits were investigated during the growth. In peel and flesh, insoluble dietary fiber (IDF) decreased regardless of cultivars while soluble dietary fiber (SDF) increased during the growth. Total dietary fiber (TDF) content in peel of 26.6％, 25.4％ and 27.7％ to 10.5％, 1.07％ and 11.9％, respectively. They were higher than TDF content in the peel of Korean tangerine. The IDF contents of their peels were higher than SDF content of them, but reverse results were found in flesh near the maturation time. The ratio of SDF content to IDF content in the peel and flesh during the whole growing time increased continuously. Contents of neutral detergent and acid detergent fiber in peel and flesh decreased with the pear growth. Hemicellulose content of peel decreased from 11.3％ to 1.3％ in Pungsu, from 16.5％ to 1.2％ in Shingo and from 10.6％ to 1.8％ in Chuhwang, respectively. The cellulose content also showed the similar result. Lignin contents of the peel and flesh were decreased continuously during the whole growing period.
