    Abstract:
    Experiments were conducted to test the effects of pre-harvest bagging on fruit ripening and quality of peach (Prunus persica Batsch cv. Hujingmilu). Young fruits, at 50 days after full bloom (DAFB), were covered with bags made of single-, double-, and triple-layers of orange paper bag with 27.0%, 13.9% and 8.2% sunlight transmission, respectively. Ethylene production and respiration rate were measured, and fruit quality was analyzed at 111, 114, 117, 120 (firm-ripe stage) and 124 DAFB (full-ripe stage). Single- and triple-layer bagged fruits had higher ethylene production rates than double-layer bagged and un-bagged fruits. The skin of un-bagged fruit had higher brightness (L-value) but smaller hue angle (h degrees) at the full-ripe stage compared with that of bagged fruit. Flesh firmness of un-bagged fruit was higher than that of bagged fruit until the firm-ripe stage, although triple-layer bagged fruit had higher firmness than un-bagged fruit at the full-ripe stage. Total soluble solids in juice of single-layer bagged fruit were a little higher than those of other treated fruits at the full-ripe stage. Single-layer bagged fruit showed the highest level of gamma-decalactone, a main characteristic aroma of peach and total lactones at the firm-ripe and full-ripe stages. It was concluded that 'Hujingmilu' peach had high quality with abundant aromas when the fruits were bagged with single-layer orange paper bags at 50 DAFB. The biosynthesis of gamma-decalactone and other aromas may be affected by light to some extent.
