Sažetak
In order to receive reliable results in the effect of preharvest calcium chloride (CaCl2) application on fruit growth and sensory characteristics of kiwifruit (Actinidia deliciosa cultivar ‘Hayward’) at the harvest time, a field experiment was carried out in two commercial orchards at different locations. The vines were sprayed with CaCl2 (1.5%), one, two, or three times in 35, 85 and 125 days after full bloom. The results showed that CaCl2 treatment significantly reduced fruit size, fresh weight and total dry matter content. Moreover, fruit growth relative attributes such as relative growth index, daily relative growth rate, daily transpiration rate, total carbon received by fruit and yield threshold pressure significantly decreased by thrice application. After thrice application of CaCl2, fruits showed better sensory quality. Overall, one time preharvest CaCl2 application had no-significant effect on the most fruits characteristics, while thrice application of CaCl2 could delay fruit ripening process.
