Abstract
Among the most important mineral nutrients Calcium is involved in determining fruit quality. There is one approad to increase fruit firmness, how to harvest, transport and storage of kiwifruit in Iran is not appropriate and resulting damages caused by careless use of traditional methods in the field to offer to the consumer is very high. How harvest, transport and storage of kiwifruit, in Iran, it is inappropriate and resulting damages caused by the careless use of traditional methods that have been cropping up a lot of supply to the consumer. Thus, the present study was to investigate the effect of different levels, summer pruning and calcium on quantitative and qualitative characteristics kiwifruit variety Hayward was done The experiment based on a factorial, randomized complete block design with two factors, the summer pruning levels (0, 2, 4 and 8 leaf, of the last fruit) and calcium chloride concentrations (0, 5/1 percent), and a total of 8 treatments carried out. After treatment, the qualitative and quantitative properties of harvested fruits contain soluble solids (TSS), acidity (TA), fruit firmness, fruit weight, length, diameter, volume and fruit tissue calcium was evaluated. Results of data analysis showed that interactions and separate summer pruning and calcium chloride on soluble solids (TSS), fruit firmness, fruit weight, fruit tissue calcium was significant. Average data showed that the highest amount of calcium in the fruit tissue (1/93%) and the highest firmness (11/73) in the treatment of the interaction of light pruning and calcium chloride 1/5 percent isTherefore, the combination of summer pruning and calcium chloride to kiwifruit variety Hayward Resulting in greater resistance to mechanical damage during harvest and transport the fruit will be ware.
