Resumo: The benefits of calcium applications pre and postharvest on fruit storage ability have been mentioned in the bibliography. It was objective of this work to study the effect of calcium preharvest application in two different forms and calcium chloride application postharvest on 'Hayward' kiwifruit storage ability. Kiwifruit vines were sprayed with 0.03% CaCl2 or 0.03% CaO at one, three and four months before harvest. The control did not have any treatment. After harvest, half fruits were dipped for 2 min in a solution of 1% CaCl2, left to dry and stored at 0 degrees C. The other half was stored at the same temperature without any treatment. The commercial yield was not affected by treatments. During storage, fruits dipped in 1% CaCl2 softened slower and than fruits not treated. Weight loss was higher in fruits treated with CaO preharvest. SSC showed a significant decrease in fruits sprayed with CaO from 4 to 6 months storage. This work suggests that immersion of kiwifruit in 1% CaCl2 postharvest benefits storage life capacity; preharvest spraying with CaCl2 seems to be better than with CaO. However, we have to try higher calcium concentrations in order to get better results in storage ability but, without causing toxicity on the vines.
