Nitric Oxide Extends the Postharvest Life of Water Bamboo Shoots, and MAP improves the effect of NO

Harvested water bamboo shoots can be stored for only a few days before they lose weight?and become soft. Nitrogen oxide (NO) and modified atmosphere packaging (MAP) have previously?been used to prolong horticultural crop storage.?In the present study, we analyzed the joint effect of?these two methods on extending the postharvest quality of water bamboo shoots. Water bamboo?shoots were treated with (1) 30 ?L L?1 NO, (2) MAP, and (3) a combination of NO and MAP. The NO?treatment delayed the softness and weight loss through maintaining the integrity of the mitochondrial?ultrastructure and enhancing the ATP level by activating the expressions and activities of succinic?dehydrogenase, malic acid dehydrogenase, and cytochrome oxidase. MAP improved the effect of NO?on the mitochondrial energy metabolism. These results indicate that NO and MAP treatments are?effective at suppressing the quality deterioration of water bamboo shoots, MAP improves the effect?of NO in extending postharvest life, and NO may be the main effective factor in the combination of?NO and MAP. ? The picture shows the effects of NO and MAP treatment on the color and skin-wilting of water bamboo shoot?stored at 4 ?C for 0, 14, and 28 d.
