非洲菊规模化扩繁生产技术研究

    Study on production technology of large scale propagation of gerbera

    • 摘要: 基于生产实践,对非洲菊扩繁生产中的继代增殖培养、壮苗生根培养、瓶栽移栽基质及育苗方式进行研究,结果表明:在增殖培养阶段将KT、BA两种激素交替使用或将KT、BA结合使用可有效避免由于激素使用不当,过早引起种苗弱化甚至玻璃化,可使大批量中间繁殖体在继代过程中稳定增殖;切割操作以“去叶留1/2基部愈伤组织丛芽小块”为非洲菊继代增殖的最佳操作方式;继代转接后前3 d不进行光照可有效节约15%左右的光照耗能;降低细胞分裂素和提高生长素用量,可达到壮苗和增殖同步的效果,也有利于分离切割提高工作效率和之后的生根培养;生根培养中适宜培养基为1/2 MS+IAA 0.5 mg/L+IBA 0.5 mg/L+AC 1.0 g/L;移栽培养宜采用湿润育苗技术。

       

      Abstract: Based on production practice, three aspects of expanding propagation production of gerbera were studied. Experimental results showed that in the multiplication culture stage, interchangeably using two hormones KT and BA or combine using KT and BA could effectively avoid weaken and vitrification of seedlings at too early stage caused by improper use of hormone, and could make large quantities of intermediate propagule stable proliferation during the subculture process. The best practices of subculture multiplication of gerbera was cutting operations to “remove leaves and remain small pieces of 1/2 basal callus clump buds”, and without lighting can effectively save about 15% of light energy in the first 3 d after transgenerational transfer. Lower cytokinin and increase dosage of auxin could achieve the effect of the synchronous seedling and proliferation and was beneficial to separate cutting to improve work efficiency and rooting culture, and the suitable medium for rooting culture was 1/2MS+IAA0.5 mg/L+IBA0.5 mg/L+AC1.0 g/L, and during transplanting culture, the technology of moisture seedling cultivation was used.
