Abstract： An experiment was conducted in Baishui County，Weinan City， Shaanxi Province，to investigate theeffectsof differentreflectivefilmsonapplecolorationand quality，aiming toprovideatheoretical basis for their scientific application inorchards.The experiment involved two apple cultivars，‘Ruiyang’and‘Red Fuji’，and included six treatment groups：‘Ruiyang’with no mulching，silver reflective film，and biodegradable reflective film；and‘RedFuji’with the same three treatments.The results showed that，compared with no mulching，both reflective film treatments significantly improved the colorationand internal qualityof‘Ruiyang' and‘Red Fuji’.Silver reflective film significantly increased the a * value，a */b* value，soluble solids content（SSC），and SS/TA ratio，and significantly decreased the b* value and titratable acidity in both cultivars. Biodegradable reflective film significantly increased the L* value，a value，a */b* value， SSC，and SS/TA ratio of‘Ruiyang’，and significantly decreased titratableacidity，but hadno significant efect on thecolor parameters or internal qualityof‘Red Fuji’.Considering the environmental impact and the efects on fruit coloration and quality，biodegradable reflective films are recommended for‘ Ruiyang' .
