The impact of harvest date and coating type on storage of the Valencia Orange varieties, Bazman, Iran
Journal Title: International Journal of Farming and Allied Sciences - Year 2017, Vol 6, Issue 1
Abstract
This study, carried out to investigation of the effect of harvest date and coating type on the storage of the Valencia orange varieties using factional experiment based on a randomized complete block design with three replications. The harvest date (December 6 and 21, January 5 and 20) and coating type (control (without coating), wax and polyethylene) were considered as the first factors in four levels and second factor in three levels, respectively. After harvesting and grooming at the 6 centigrade and 87 relative humidity for two months, the storage of the fruits was detected. Results showed that the harvest date and coating type were affected fruit rot, weight loss, orange Juice content, weight of the skin and dross which were significant at the level of 1%. The harvest date of January 4 was affected fruit decay, weight loss, orange Juice content, weight of the skin and dross more than the other harvest date. Also, the ethylene coating in compression with the wax cover and control one (without coating) was significantly prevented to the reducing of the fruits decay, weight loss, orange Juice content, weight of the skin and dross. This meant that the juice loosing of the fruit with ethylene cover is less than the wax cover. Increasing of the dissolved solid materials and the titratable acidity in the control samples and waxy groomed fruit was significantly more than the ethylene covered samples which could be as a result of the decreasing juice content at these grooms. Therefore, the Valencia orange harvesting from January 4 and warping with the polyethylene cover in order to increasing of the storage and supply period, is recommended.
