Key Findings
- The study by the Chinese Academy of Sciences found that blue LED light during the day (8:00 to 18:00) accelerates grape berry coloration and increases anthocyanin content
- Blue LED light at night (20:00 to 6:00) did not significantly enhance anthocyanin accumulation compared to the control
- Daytime blue light exposure boosts the expression of genes related to anthocyanin biosynthesis and light signaling, suggesting a regulatory mechanism influenced by light conditions
