In order to study the effect of different planting areas on the color of Pomelo cv. Huangjinmiyou fruit, Pujiang and Guang’an Pomelo cv. Huangjinmiyou were used in this experiment. Brightness, red and green deviation and blue and yellow deviation of exocarp, mesocarp and pulp parts in the test samples were measured, and the composite index of color difference was calculated. The results showed that the comprehensive index of color difference in the exocarp and pulp of Pomelo cv. Huangjinmiyou from the two planting areas changed almost synchronously. But it was negative at 90 days after anthesis and positive at 120 days after anthesis in the mesocarp of Pujiang pomelo. It was still negative at 150 days after anthesis in the mesocarp of Guang’an pomelo until 180 days after anthesis. It reflects the comprehensive index of fruit color displayed by the accumulation of carotenoids. The external environment stimulates the accumulation of carotenoids. Therefore, color variation difference may be caused by different environmental factors in the two regions.
