In fact, this is not the case at all. When you walk to Gua Tian to look at the female flowers on the melon vine, as early as the flower pollination, the watermelon peel has been bathed under the sun, and the so -called "central part" is not developed at this time.

The more real reason is that the watermelon is close to the outer skin and the part close to the center comes from two different structures in development. This development difference directly affects the sweetness of watermelon.
