为了有效利用安吉白茶资源,以安吉白茶幼叶作为外植体,探讨了不同植物生长调节剂对愈伤组织诱导、增殖及茶多酚积累的影响.研究结果表明,TDZ有利于愈伤组织的诱导、增殖及茶多酚的积累,当TDZ的质量浓度为 1.0 mg/L时,愈伤组织的诱导率为92.1%,茶多酚的质量分数为20.6%,表儿茶素的相对含量为5.3%.
For utilization of Anji Baicha,the effects of different plant growth regulators on callus,proliferation and accumulation of tea polyphenols of Anji Baicha were investigated using leaf as explants.The results showed that TDZ was more effective for callus induction,proliferation and accumulation of tea polyphenols.The callus induction frequency reached 92.1 % when the concentration of TDZ was as high as 1.0 mg/L.The mass fraction of tea polyphenols was 20.6%,and the relative abundance of epicatechin increased to 5.3%.
