Abstract： To elucidate how bird-proof nets of different colors influence leaf photosynthetic characteristics and fruit quality in apple， nine-year-old Yanfu 3/M9 trees were covered with polyethylene nets in three colors （red， blue，and white）. We systematically measured leaf net photosynthetic rate， light intensity，and both external and internal fruit-quality attributes. Results showed that leaves under blue nets exhibited the highest net photosynthetic rate [19.53μmol/（m2⋅s）]， significantly higher than red nets [17.37μmol/（m2⋅s）] ，with white nets intermediate [18.96μmol/（m2⋅s）] . Blue nets significantly increased single-fruit weight （229.33g） ， surface gloss index （81.25%） ， and soluble solids content （16.83%） . Red nets produced the greatest fruit firmness （8.81kg/cm2） ，whereas white nets significantly improved the fruit coloration index （78.75%） .In conclusion， the blue bird-proof net demonstrated the most prominent advantages in enhancing leaf photosynthetic efficiency and improving overallfruit quality， indicating high potential for practical

applicationand promotion
