摘要
目的:建立高效的红花(Carthmus tinctorius L.)离体组织培养体系,为红花的基因操作搭建平台。方法:以萌发6~8d的红花无菌苗子叶为外植体,选用MS基础培养基,应用萘乙酸(1-naphthylacetic acid,NAA)+6-苄氨基嘌呤(6-benzyl amino purine,6-BA)+激动素(kinetin,KT)为组织培养的植物生长调节剂,优化红花的组织培养体系。结果:红花组织培养的最佳植物生长调节剂配方为:NAA 2.0mg/L+6-BA 4.0mg/L+KT 20.0mg/L,添加活性炭(4g/L)或硝酸银(5mg/L),光照时间为16h/d,光照强度9000lx,培养温度为(25±2)℃,平均愈伤组织发生率高达86.4%,而且再生芽生长稳定,重现性高。结论:本研究优化建立了红花的不定芽再生体系,为红花基因操作平台的建立奠定了基础。
Objective:To establish the regeneration system of safflower(Carthamus tinctorius L.),so as to create a platform of gene manipulation of safflower.Methods:Through tissue culture experiments,cotyledons germinated 6-8 days of safflower were selected as explants and cultured with Murashige and Skoog(MS)as the basal medium at(25±2)℃temperature with 16h/d illumination and 9000 lx light intensity.Results:The optimum callus medium of safflower was MS basal medium supplemented with 1-naphthylacetic acid(NAA)2.0 mg/L+6-benzyl amino purine(6-BA)4.0mg/L+kinetin(KT)20.0mg/L and addition of acticarbon(4g/L)or silver nitrate(5mg/L),which made the callus mean rate as high as 86.4%and with higher regeneration bud grow stability and reproducibility.Conclusion:The research optimized adventitious shoot regeneration system and established the foundation for safflower gene manipulation platform.
