The author made a comparative study of red grape and Kyoho grape from fruit anatomical results, respiratory characteristics, postharvest physical and chemical indicators, and endurance of fruit to sulfur dioxide. The results showed that compared with Kyoho and Kyoho, the former had a The thickness of the epidermis is large, the average diameter of sub-epithelial cells and pulp cells is also large, the number of microtubule bundles is large, the respiratory intensity is low, and the reducing sugar, crude fiber, total pectin content and stalk pull resistance are significantly higher than the latter, but the PG enzyme activity, The electrical conductivity of the pulp tissue and the endurance of the fruit to sulfur dioxide were significantly lower than the latter. When stored at room temperature for a short period of time, the storability of red extraction was significantly better than that of Kyoho. However, due to the relatively poor disease resistance in the period of red extraction and the storage period is sensitive to sulfur dioxide, the effect of long storage at low temperature is not necessarily better than that of Kyoho.
