Repeated preharvest applications of methyl jasmonate (MJ) to 'Fuji' apple (Malus sylvestris var. domestica (Borkh.) Mansf.) fruit were evaluated for impacts on peel color, size, fruit fi nish, and maturation. MJ treatments at 2 week intervals began 48 days after full bloom (DAFB) (early season) or 119 DAFB (late season) and fruit were harvested 172 DAFB. MJ treatment stimulated signifi cant increases in peel red color following the initial application and thereafter. Early season MJ treatment reduced fruit diameter and length to diameter ratio but slowed softening and starch hydrolysis. Fruit receiving late season MJ treatments had increased incidence of bitter pit and splitting, shorter green life, and slower softening. Results suggest preharvest application of MJ impacts apple color development and other aspects of fruit quality. Chemical name used: methyl 3-oxo- 2-(2-pentenyl)cyclopentane-1-acetate (methyl jasmonate). Red peel color is an important commercial grading criterion and contributes to the mar- ketability of many apple (Malus sylvestris var. domestica (Borkh.) Mansf.) cultivars. Antho- cyanins, carotenoids, and xanthophylls are the primary peel components that contribute to apple color (Sun and Francis, 1967; Workman, 1963). These pigments along with other fl avonoids also function in photoprotection (Merzlyak and Chivkunova, 2000). Methyl jasmonate (MJ) enhances anthocy- anin production in a wide variety of plant ma- terials including seedlings of soybean (Glycine max Merr.) (Franceschi and Grimes, 1991) and Arabidopsis thaliana (L.) (Feys et al., 1994), tulip bulbs (Tulipa gesneriana L.) (Saniewski et al., 1998a), and peach shoots (Prunus persica Batsch.) (Saniewski et al., 1998b). MJ also enhances anthocyanin synthesis in 'Tsugaru' apple fruit peel disks (Kondo et al., 2001) and whole 'Fuji' apple fruit peel under laboratory conditions while also stimulating production of quercetin glycosides and other phenolic compounds (Rudell et al., 2002). MJ stimulates s-carotene biosynthesis in 'Golden Delicious' apple peel in the dark (Perez et al., 1993) and in 'Fuji' peel in concert with UV/visible light along with chlorophyll b (Rudell et al., 2002). Increased red color development in apple fruit coincides with heightened jasmonic acid (JA) levels early in fruit development as well as near the onset of ripening (Fan et al., 1998). These results suggest jasmonates may be involved in promoting apple fruit anthocyanin formation in situ. Our objective was to determine if preharvest applications of MJ to 'Fuji' apple fruit alters color development and other aspects of fruit quality.
