ABSTRACT
Objective To study the effect of different treatment methods on seed germination of wild Morinda officinalis How(MOH),which will provide evidence for breeding new cultivars of MOH.Methods We observed the morphological feature,thousand-seed weight and hygroscopicity of wild MOH,and studied the effect of different treatment methods on the germination rate,germination vigor,and germination index of the seeds.Results The thousand-seed weight was 38.03 g and the seed coat had good hygroscopicity.Stripping seed coat,acid etching with sulfuric acid,and the combined treatment of stripping seed coat with exogenous hormones of gibberellin(GA) and 6-benzyladenine(6-BA) had an effect on increasing germination rate,and the germination rate arrived 88.89% after the combined treatment of stripping seed coat with 4 mg/L 6-BA.Conclusion The germination inhibitors containing in the seed coat mainly contribute to the difficulty of the germination of MOH,and the germination inhibitors containing in the seed also have some influences on the germination.
