- 摘要:
- 以自然风干的多年生大白杜鹃种子为试材，采用双因子试验设计方法，研究了培养基和赤霉素浓度对种子萌发率以及幼苗生长的影响，以探讨大白杜鹃种子无菌萌发和幼苗生长的条件。结果表明：以1/2MS培养基，添加2.0 mg/L GA，在25℃温度条件下，大白杜鹃种子无菌萌发率最高，达77%，且幼苗生长状况良好。
- Abstract:
- In order to explore optimum conditions of seeds aseptic germination and seedling growth on Rhododendron decorum Franch,the double-factor design was adopted,the effect of gibberellin and medium on seed germination rate and seedling growth were studied.The results showed that medium dominated by 1/2MS modified with 2.0 mg/L GA at 25℃ was the best conditions for aseptic germination and seeding growth of R.decorum Franch,the germination rate could reach 77%.
