Abstract
In this study, the effect of foliar spray with calcium chloride (0, 0.75, 1.5 and 3 g L-1) during 2, 4 and 6 weeks before commercial harvesting time of apple fruit cv. ‘Gala’ and ‘Delbarestival’ which trained in three different systems (V shape, HighTech and Cordon) was investigated. The results showed that types of training systems and foliar application of calcium can affect on fruits quality at harvest time. Tree yield, fruits weigh and fruit tissue firmness of ‘Gala’ was significantly higher than ‘Delbarestival’. Furthermore, calcium spray increased fruit firmness in compared to control and TA deacresead in compared to control. Calcium treatment increased fruit skin a* value that means more antocyanin synthesis and redness. Results generally showed that ‘Gala’ apple trained in HighTech and V shape systems as well as ‘Delbarestival’ in HighTech produced the higher fruits weight and size as well as quality favorite in compare to other system.
