| Outline of Final Research Achievements |
The fruit of melting-flesh peach (Prunus persica (L). Batsch) cultivars produce high levels of IAA. IAA induce increased level of ethylene caused by high expression of PpACS1, resulting in rapid fruit softening at the late-ripening stage. In this study, we examined the regulation of fruit softening using some inhibitors of auxin biosynthesis. The melting -flesh peach which were treated with inhibitors, produce lower level of ethylene and keep firmer than control fruit. The cell wall modifying isonzyme 3 may some effect on melting-flesh during fruit softening.
