Abstract: Three infinite-growth tomato cuhivars(FA 189，Hangza 1 and Shanghai 919)were used to study the fruit storage ability and the changes of the contents of soluble solid，reduced sugar，sucrose and titratable acid in tomato fruit during
storage time at room temperature．It was found that the fruit storage tolerance varied greatly among the three cultivars．Among which，the storage tolerance of FA 189 Was the highest and the storage tolerance of Shanghai 919 was the lowest．The changes offruit firmness showed a simi~ tendency to fruit storage ability．During the fi'uit storage period，the contents of soluble solid，reduced sugar，sucrose and titratable acid markedly decreased．The contents of soluble solid and reduced sugar in Hangza 1 were higher than the other two euhivars，while the titratable acid content Was lower than that of FA189
and Shanghai 919．
