Abstract

Abstract: In order to explore the methods to improve the coloring and quality of Citrus reticulata Blanco var. orah, the experiment of spraying glucose and ABA on postharvest Orah was carried out. The results showed that sprayed glucose had an obvious effect on improving the solid-acid ratio of Orah. The solid-acid ratio of Orah PT3 sprayed with 1% glucose twice was 29.50, and that of Orah PT4 sprayed with 5% glucose twice was 30.98, which were 24.68% and 30.94% higher than CK, respectively. Sprayed ABA had a certain effect on improving the red value a* and the comprehensive coloring index CCI. In the added value of a*, the added value of 10 mg/L YK2 treatment was 3.65, and that of 50 mg/L YK3 treatment was 3.88, which was significantly different from that of CK. It was recommended that 0.1%~1% edible glucose should be sprayed to improve the solid-acid ratio, and 5~10 mg/L ABA should be sprayed to improve the coloring, thereby prolonging the shelf life and improving the quality of Orah.

Key words: Citrus reticulata Blanco var. orah, glucose, ABA, coloring, quality
