Effects of preharvest chitosan application on relative expression of ethylene biosynthesis-related genes (a) AdACS2 and (b) AdACO2 during cold storage in ‘Garmrok’ kiwifruit. Vertical bars indicate SE with n = 3. Actin gene was used as internal control and the quantitative RT-PCR data were analyzed using the 2−ΔΔCT method. * Statistical difference caused by chitosan treatment was compared to untreated fruit (control) of each sampling date (p ≤ 0.05).
