To investigate the effects of sodium nitroprusside（SNP） treatment on energy metabolism in ginger rhizomes， ginger rhizomes was dipped in 0 and 0.25 mmol/L SNP for 10 min and then stored at room temperature. The activities of H+-ATPase， Ca2+-ATPase， succinate dehydrogenase （SDH） and cytochrome oxidase（CCO） in mitochondria， content of ATP， ADP， AMP and energy charge were determined during storage. The results showed that the activities of H+-ATPase， Ca2+-ATPase， SDH and CCO were enhanced by SNP treatment. SNP treatment also delayed the decrease of ATP and ADP contents and energy charge in mitochondria of ginger rhizomes. These results suggested that SNP treatment can maintain higher energy levels through regulation the activity of enzymes in energy metabolism to delay the senescence and keep the quality of ginger rhizomes.
