AbstractThe leaf color of leaf mustard is controlled by a pair of alleles.The green-leafed variety 20Z6 and the purple-leafed variety 2OZ5 were the near-isogenic lines.To investigate whether natural allelic variation controlling leafcolor affects the storagecharacteristics of leaf mustard，we stored both the green-leafed and purple-leafed varieties under low temperature （ 5‰ ） and compared their storage characteristics during the storage period.The results showed that after 9 d of low-temperature storage，there was no significant diference in weight loss rate between green-leafed and purple-leafed leaf mustard.During low-temperature storage period，the contents of chlorophyll，anthocyanin，total phenols，soluble protein （at 3 and9 days after storage） and total soluble solids of the purple-leafed leaf mustard were significantly higher than those of the green-leafed variety.However，the activities of peroxidase，catalase and ascorbate peroxidase in the purple-leafed leaf mustard were not significantly higher than those in the green-leafed variety. These results suggested that the storage characteristics and nutritional quality of purple-leafed leaf mustard were significantly superior to those of greenleafed leaf mustard.The enhanced storage tolerance of purple-leafed leaf mustard was primarily atributed to higher levels of non-enzymatic antioxidants such as phenol compounds，but was largely unrelated to the activities of reactive oxygen metabolic enzymes such as peroxidase， catalase and ascorbate peroxidase.In summary， purple-leafed leaf mustard exhibited higher nutritional qualityand stronger storage tolerance compared to green-leafed leaf mustard，suggesting thatthe allelic variation controlling color trait influence the storage tolerance of leaf mustard. These results could provide technological insights for the breeding of new leaf mustard varieties with strengthen storage properties.
