Abstract:

Effects of coverage of vapor permeable light reflecting film and silver\|black light reflecting film on fruit coloring, soluble solid contents, titratable acid content and sugar accumulation in fruit of Satsuma mandarin (Citrus unshiu Marc.) were studied. The results showed that mulch with vapor permeable light reflecting film improved fruit coloring. The a* value of color parameter was significantly increased in mulch treatment during fruit coloring and thus the fruits of mulch treatment showed redder color compared with the control. Soluble solid contents increased by 1.5 and 0.5 Brix° compared to the control after mulch with vapor permeable light reflecting film and silver black light reflecting film, respectively. Titratable acid content also slightly increased. The glucose, fructose and sucrose content increased in fruit mulched by light reflecting film, especially for glucose and fructose content. However, vapor permeable light reflecting film was more effectively than silver black light reflecting film.

Key words: Satsuma mandarin, vapor permeable reflecting film, mulch, fruit quality
