Study on Germination Characteristics of Artemisia indica Willd.Seeds

摘要(Abstract):

[Objective] The aim was to investigate the germination characteristics of Artemisia indica Willd.seeds cultured under different conditions.[Method] Germination tests were carried out to evaluate the effects of different germination beds,temperature,illumination,pH value,water potential,planting depth,pretreatment,storage methods and storage time on germination of Artemisia indica Willd.seeds.[Result] The results showed that the seeds on paper(TP) assumed the highest germination rates,which was 94.32%.The suitable range of germination temperature of the seeds was from 20 to 35 ℃,and the germinability and germination rate were 67.50% and 93.25% respectively cultured at 25 ℃.Illumination had no effect on the germination of the seeds.The germination rate was 80.21% to 92.98% with pH of 4-10.The most suitable solution potential was 0--0.2 Mpa,with the germination rate of 88.25%-93.02%,and the most suitable soil depth was from 0 to 1 cm,with the germination rate of 92.53%.Gibberellin is conducive to the germination of the seeds and the vitality of seeds can be maintained for longer time storage in refrigerator.[Conclusion] The study revealed the germination characteristics of Artemisia indica Willd.seeds and the optimum culture conditions,which would provide reference for the further introduction and cultivation of Artemisia indica Willd..
