不同植物生长调节剂对芍药种子萌发及幼根生长的影响
Effects of Different Plant Growth Regulator Treatments on Seed Germination and Radicle Growth of Paeonia lactiflora
摘要
Abstract
In order to investigate the effects of different plant growth regulator treatments on breaking seed dormancy,promoting germination,and enhancing early seedling growth of herbaceous peony,seeds of the peony cultivar'Fengdanbai'were used as experimental materials.The effects of soaking treatments with different concentrations of melatonin(MT),gibberellin(GA3),and 6-benzylaminopurine(6-BA)on germination rate,germination potential,germination index,as well as radicle length and fresh root weight and soluble sugar content were studied.The results showed that appropriate concentrations of plant growth regulators effectively broke peony seed dormancy,significantly improved germination indices,and promoted radicle growth.The results indicated that treatment with appropriate concentrations of plant growth regulators can effectively overcame seed dormancy of peony(Paeonia),significantly improve germination parameters,and promote radicle growth.The optimal concentrations were determined as 200 mg·L-1 for GA3,200 μmol·L-1 for MT,and 100 mg·L-1 for 6-BA.Among these,treatment with 200 mg·L-1 GA3 for 24 hours exhibited the most pronounced effect,with germination percentage,germination energy,germination index,and radicle growth indicators all significantly higher than those of other treatments and the control.Furthermore,all three plant growth regulators showed a clear concentration-dependent effect,wherein the promoting effect first increased and then decreased with increasing concentration.关键词
