*3.1. Fruit Weight and Size at Harvest*

The chitosan-treated fruit had the highest fruit weight of 86.27 and 91.79 g (*p* ≤ 0.05) at 100 and 500 mg·L−<sup>1</sup> concentrations, respectively (Table 1) when compared with the average weight of the control fruit (81.49 g). The fruit size was measured by means of fruit length, longitudinal width, and transverse width. There was no difference in fruit length and longitudinal width between the treatments, except for the transverse width (Table 1). The smaller values of transverse width of 50.28 and 51.86 mm were measured for fruit treated with 100 and 500 mg·L−<sup>1</sup> chitosan, respectively, and a larger value of transverse width was observed for the control fruit (52.06 mm).

**Table 1.** Effects of preharvest chitosan application on fruit weight and fruit size at harvest in 'Garmrok' kiwifruit. Experimental data represent means ± standard error with n = 10. \* in each column indicate significant differences between treatments on harvest day, according to the least significant difference (LSD) test at *p* ≤ 0.05.
