摘要: 探讨小茴香种子最佳处理技术;以小茴香的茎段和叶片为外植体,诱导愈伤组织,为小茴香的细胞培养和再生体系建立奠定基础。将小茴香种子进行温水处理、GA处理等,比较发芽率。加入含有0.1mg/L赤霉素(GA)的温水中浸泡,放在摇床上摇1~2 h后,栽在花盆中获得栽培苗;将栽培苗的茎段和叶片作为组培材料,茎段和叶片的升汞最适消毒时间分别为4min、3min。然后放到合适的培养基上进行愈伤组织诱导。GA处理后的种子发芽率最高。由茎段和叶片诱导愈伤组织时,最佳培养基分别为MS+蔗糖+琼脂+2.0mg/L6-BA+0.5mg/L NAA、MS+蔗糖+琼脂+2.0mg/L6-BA+0.7 mg/L NAA。确定小茴香种子栽培时获得最高发芽率的条件,初步筛选出小茴香愈伤组织诱导最佳条件。

Abstract: Objective The purpose of this experiment is to induce calli with stem sections and leaves of dill as explants,and lay the foundation of dill regeneration system establishment.Methods The dill seeds were incubated in warm water containing 0.1 mg/L gibberellic acid(GA) in shaker for 1-2 h,then planted in pots.The stem sections and leaves were separated from the cultivated plants,and dipped into mercuric chloride to sterilize for 4 min and 3 min,respectively.Afterwards,these explants were settled on culture medium for callus induction.Results The suitable culture mediums for callus induction from stem section and leaf were MS +sucrose +agar +2.0mg/L6-BA +0.5mg/L NAA and MS +sucrose +agar +2.0mg/L6-BA +0.7mg/L NAA,respectively. Conclusion In this paper,we have established the callus induction system with stem sections and leaves of dill successfully.
