Physicochemical Characteristics in Fruit of Page Mandarin (Citrus reticulata) on Different Rootstocks

The aim of this study was to determine physicochemical characteristics in fruit of Page mandarin (Citrus reticulata) on different rootstocks. This study was conducted at Ramsar Research Institute in a completely randomized design with 4 treatments and 3 replications in 2015. The content of individual sugars in fruits was determined by HPLC. Total acidity (TA) and pH value of juice was also evaluated. Total carotenoids and chlorophylls content was measured using a spectrophotometer. Crude fat was extracted using Soxhlet`s apparatus .Crude protein was measured by Kjeldahl’s method. Total dry matter was determined by dehumidify of fruits in an oven at 80˚C. The results showed that, the highest of total sugars (107.35 mg/ mL), pH (3.50) and carotenoid (0.14 mg/ g) were in fruit of Page mandarin (Citrus reticulata) grafting on the Troyer citrange. According to results, the amount of total acid (0.73 %) of Page mandarin grafted on sour orange was higher than those of other rootstocks.
