Abstract :

This study aimed to evaluate the effects of calbron and calcium chloride on some quantity and quality traits of Red, Golden delicious and Fuji apple on MM106 in an factorial trial in randomized completely block design with 3 replications. Percentage initial and final fruit drop, fruit weight, vitamin C, total soluble solids, titretable acidity, pH were determined. The results indicate that the highest effects on the initial and secondary fruit drop relating to Red delicious (18.54, 43.33%) and the lowest ones on Fuji (14.76, 39.18%). Also, increasing the amount of vitamin C in Fuji and Golden Delicious cultivars, by spraying calcium chloride was observed in comparison with control. No significant differences were found in pH and acidity in Fuji and Red Delicious with control. Spraying with calcium chloride followed the greatest impact on the amount of total soluble solid in the Fuji cultivar. The different cultivars that we used in this experiment, in addition, the presence of genetic many of the characters were different too. That showed different response to the treatments that we used. In conclusion foliar applications of calbron and calcium chloride have the greatest effect on Fuji and the lowest ones on Red delicious apple.
