Abstract:
Taking the seeds of Anemarrhena asphodeloides as materials,the germination potential,germination rate,radicle length and germ length of Anemarrhena asphodeloides seeds were studied under PEG stress and mixed salt stress,in order to provide scientific basis for artificial cultivation of A.asphodeloides.The results showed that as the increasing of the concentrations of PEG and salt,the seed germination of A.asphodeloides was inhibited,the germination potential,the germination rate，length and diameter of radicle and germ showed a significant negative correlation with it. Under the PEG stress,A.asphodeloides seed germination potential decreased from 16% to 4%,the germination rate decreased from 80% to 52%,and the lethal concentration of the seed germination was 15%. Under the stress of NaCl and NaHCO3 (1∶1) mixed solution,the A. asphodeloides seed germination potential decreased from 16% to 6%,the germination rate decreased from 80% to 14%,and the A. asphodeloides seed germination lethal concentration was 1.20%.The results showed that the A. asphodeloides seed has certain resistance to drought and salt stress.
