*3.3. Loss of Fruit Weight*

The loss of fruit weight for all treatments displayed a similar increasing pattern as the storage period proceeded (Table 2 and Table S3). Preharvest chitosan application (100 and 500 mg·L−1) deterred the weight loss of 'Garmrok' kiwifruit during the cold storage, and the highest (*p* ≤ 0.05) weight loss was observed in the control fruit (Table 2). Although the weight loss appeared to be slightly higher at 500 mg·L−<sup>1</sup> chitosan than 100 mg·L−<sup>1</sup> chitosan, they were not statistically significant. The greatest loss of fruit weight for each treatment was observed at the end of storage (90 days), as shown as weight loss of 1.8%, 2.2%, and 2.3% for 100, 500 mg·L−<sup>1</sup> chitosan and control treatment, respectively.
