The fruits were stored for 3 months in normal storage. The antioxidant properties, elements and enzymes were evaluated at the time of harvest and during the storage period at intervals of one month. The results showed that the use of higher concentrations of calcium nitrate and potassium phosphite improved the characteristics measured on the day of harvest. Fruits treated with 4 g L-¹ calcium nitrate and 3 g L-¹ and 1.5 g L-¹ potassium phosphate had the best effect on antioxidant properties and elements. Also, the amount of APX and SOD enzymes increased with these treatments during the storage period.</span></span></span></span></div> سانگین, آنتوسیانین, فنول‌, ویتامین C Sanguine, Anthocyanin, Phenol, Vitamin C 437 446 http://journal-irshs.ir/browse.php?a_code=A-10-276-1&slc_lang=fa&sid=1 Amirali Mohammadi امیرعلی محمدی Amiralimohammadi72@yahoo.com 10031947532846008766 10031947532846008766 Yes Mazandaran Agricultural and Natural Resources Research and Education Center مرکز تحقیقات و آموزش کشاورزی و منابع طبیعی مازندران Mehrdad Shahabian مهرداد شهابیان mshahabian@yahoo.com 10031947532846008767 10031947532846008767 No Mazandaran Agricultural and Natural Resources Research and Education Center ، مرکز تحقیقات و آموزش کشاورزی و منابع طبیعی مازندران Mahmoud Reza Ramezanpour محمودرضا رمضانپور mrramezanpour@yahoo.com 10031947532846008768 10031947532846008768 No Mazandaran Agricultural and Natural Resources Research and Education Center ، مرکز تحقیقات و آموزش کشاورزی و منابع طبیعی مازندران
