Quantitative Proposal of Tangerine Fruit Size Standard

บทคัดย่อ

This research was to study the distribution of tangerine fruit size and propose quantitatively draft of its standard. Methodology comprised i.) collection of tangerine fruit mechanically sized by 5 popular perforated
cylindrical type sizing machines at random, 5 sizes per machine, 50 fruits per size ; ii.) measurement of diameter of all fruit samples and iii) calculation of optimal seperation line between any two related sizes. The result revealed that tangerines were commercially divided into 5 sizes, ie. No. 3 (the smallest size), 2,1,0, and 00 (the biggest size). Standard size of different grade tangerine fruit was proposed as follows; diameter size ranges of no. 3, 2, 1, 0 and 00 were 43-46, >46-51, >51-56, >56-62 and >62-66 mm., respectively.
