Abstract:
Studied the effects of salt stress on seed germination and young seedling growth of Apocynum venetum.The results showed that the optimal germination was obtained under control conditions and salt content was 20%;With the rising of the salt stress,the activities of SOD,POD and the praline content first increased and then reduced,and they reached the maximum values when salt content was 60%;The contents of MDA first were reduced and then increased as concentrations of the salt increased,and they reached the minimum values when salt content was 40%.These results suggested that the seedling growth of Apocynum venetum suitable for some concentrations of salt,but its seed germination was suitable for saltless and low-salt environment.
