Abstract:

Fruit expansion rule and dynamic change of soluble solid content of different batches of ‘Cuimi’ kumquat was studied. ‘Cuimi’ kumquat in Rong’an County of Guangxi was used as the experimental material. The transverse diameter and longitudinal diameter of the fruit were measured during the expansion period of different batches of fruits, and the soluble solids content of the fruit was measured at the maturity stage. The results showed that in the fruit enlargement stage of ‘Cuimi’ kumquat, the first and second batches of fruits were easy to form large fruits, and the third batch of fruits was smaller. In the early stage of fruit ripening, the soluble solids content of the second batch of fruit was the highest, and in the middle and late stages, the soluble solids content of the third batch of fruit was the highest. The results showed that the first and second batches of fruits expanded early, lasted for a long time to form large fruits, and the soluble solid content was also high, and the market price was high. Therefore, corresponding measures should be taken to preserve the first and second batches of fruits in production, so as to improve the yield and increase the benefit.

Key words: ‘Cuimi’ kumquat, different batches, fruit swelling, soluble solids, dynamic change
