The effects of ascorbic acid (ASA) on the seed dormancy of Malus sieversii were investigated in this study. Firstly, the dormant seeds during different periods of cold stratification were stripped of their coats and incubated for 7 d to investigate the germination, endogenous ASA content and L-galactose-1, 4-lactone dehydrogenase (GLDH) activity. In part two, the dormant embryos without coats were treated with exogenous ASA and lycorine (Lyc) to measure the germination, endogenous ASA, GLDH, α-amylase, and GA. The results show that after the cold stratification, ASA and GLDH increased significantly before the onset of dormancy breaking, and the seed coat was not the determinant factor for maintaining dormancy. In addition, exogenous ASA increased the dormancy breaking, germination, endogenous ASA, GLDH, α-amylase, and GA, whereas Lyc showed the opposite effects. It reveals that ASA participates in the onset of dormancy breaking of Malus sieversii seeds, and it is able to break dormancy. On the other hand, Lyc significantly inhibits GLDH activity, and reduces endogenous ASA, thus ultimately prolonging seed dormancy. Furthermore, exogenous ASA enhances α-amylase activity and increases endogenous GA accumulation of the seeds, and ultimately promotes embryo dormancy breaking.
