Abstract:

The type of sugar accumulation of Watermelon fruit is "intermediate type".Their photosynthetic production are raffinose and stachyose, and by this form to transport.But finally the sugar into the fruit is sucrose yet. Therefore, sucrose is the main form of sugar accumulation and the important factor of fruit quality in many kind of fruit. During the process of sugar accumulation of watermelon fruit, the sucrose invertase, sucrose phosphate synthase and sucrose synthase are the most important metabolic enzymes. At the same time, fructose and glucose are controlled by these enzymes. So, these enzymes make the three kinds of sugar that sucrose, fructose and glucose become balance at the time of watermelon fruit maturity.
