Abstract: In the process of Feicheng peach Prunus persica(L.)Batsch ev.Feicheng]fruit ripening,
the proportion of cell wall to fruit mass decreased.Soluble pectins increased remarkably from July 31 to August
16,leading to fruit firmness decrease. The ionieally bound pectin remained stable in ‘Baili Feiehengtao’
peach,but it decreased in ‘Hongli Feiehengtao’peach.Decrease of cellulose content in cell wall also played
an important role in the reduction of firmness.Both PME and cellulases played important role in peach fruit soltening.
Th e results from the two cuhivars implicated that eellulase is more important in fruit softening.Endo·PG
had not been detected in ‘Feicheng’ peach.Exo·PG took part in the process of later stage of ripening.
