【摘要】 以兴国九山姜为材料,研究多效唑在生姜试管苗快繁、壮苗、移栽及种质保存中的应用。结果表明:在生姜试管苗扩繁培养基中,附加1.5mg/L多效唑可使试管苗增殖与壮苗同步进行,大大提高移栽成活率。在MS+8.0～10.0mg/L多效唑的培养基中,生姜试管苗的种质保存期可延长至4～5个月。更多还原

【Abstract】 In the experiment, using MS medium as basic medium and Xingguojiushan ginger as material, the effects of PP333 on multiplication, strengthening, transplant, and conservation in vitro are studied. The results showed that adding 1.5 mg/L PP333 to multiplication medium, strengthening can be finished with multiplication of seedling in vitro. The seedlings in vitro get lower and stronger, roots developed. The survival rate of transplant is highly increased. Adding 8-10 mg/L PP333 to MS medium, the period of conservation of ginger in vitro at normal temperature can be prolonged to 4-5 months.更多还原
