Abstract

Abstract: In this paper, the effect of MA (modified atomosphere) storage on respiration, ethylene production, flesh firmness, relative membrane permeability, total soluble solid and activities of PG and CX of nectarines were studied. The results showed that MA storage significently inhibited PG (polygalacturonase)
and CX ( cellulase) activities, decreased the respiration rate and the ethylene production, delayed the respiration peak and the ethylene peak, and slowed down the decrease in the flesh firmness and the increase in the relative membrane permeability. However, there was no remarkable effects of MA storage on the total soluble solids. There is a potential application of MA storage in the nectarines.

Key words: Nectarine, MA storage, Postharvest physiology, PG, CX
