- 摘要:
- 以朱顶红新品种‘苏红’与‘风车’的鳞茎为试材，采用切割繁殖、组培繁殖方法对2种朱顶红新品种进行了繁殖技术的研究，以提高朱顶红繁殖效率，加速朱顶红新品种的推广。结果表明：切割繁殖使这2个品种繁殖率和生长量差异明显，‘苏红’繁殖率和切割5个月后的子球生长量大于‘风车’；组培繁殖采用鳞茎切割后的小子球，2个品种最适的初代消毒方式为75%的酒精30 s，0.1%升汞18 min，饱和次氯酸钙20 min；消毒后的小子球进行4分切割后组培增殖最快，污染率最低。
- Abstract:
- To promote the propagation efficacy of Hippeastrum，bulb cutting and tissue culture were studied for new cultivars by ‘Suhong’ and ‘Fengche’.The results showed that the reproduction rate and the growth rate of baby bulb after 5 months of ‘Suhong’ were bigger than ‘Fengche’.Baby bulb from bulb cutting was used in tissue culture.For two cultivars，the optimized disinfection program was disinfect baby bulb with 75% alcohol for 30 seconds，0.1% mercuric chloride 18 minutes and saturated calcium hypochlorite 20 minutes.After disinfection quarter cutting was used to cut baby bulb.This system had the highest reproduction efficacy and the lowest pollution rate.
