Ripening and ethylene production affected by 1-MCP in different parts of kiwifruit during postharvest storage

Ethylene plays an important role in kiwifruit ripening. However, it is unclear whether there are differences ethylene production different parts of during postharvest Kiwifruit were treated with 0.5 μL L−1 1-MCP for 12 h at 20°C and stored 20 ± 1°C. The results showed the firmness, soluble sugar, total solids (TSS), AcACS1 AcETR2 gene expressions highest core, starch, AcACO2, AcACO3 seedless pulp harvest. Starch content firmness decreased significantly, sugar content, TSS, increased significantly all On other hand, can inhibit these changes fruits respiration rate expression first then reduced suppressed by 1-MCP. was detected core seeded 3 9 d storage, respectively, but not pulp. Overall, suggested softening, production, related harvest ripening, inhibited softening
