目的对一点红进行组织培养研究,探讨在短时间内快速繁殖一点红种苗的方法。方法以一点红带有腋芽的茎段为外植体,用MS+BA1·5mg/L+NAA0·1mg/L培养基。结果经30d诱导培养,可得丛生芽4~5个;小芽苗转入1/2MS+NAA1mg/L培养基上诱导生根,20d后可长成具有3~4条根系的再生植株。结论此途径为人工栽培一点红提供优质种苗。
Objective To study the tissue culture of reddish red and discuss the method of rapidly propagating the red seedling in a short period of time. Methods The shoots with axillary buds were used as explants with MS + BA1.5mg / L + NAA0.1mg / L medium. Results After induction for 30 days, 4 to 5 shoots were obtained. Small shoots were transferred to 1 / 2MS + NAA1mg / L medium to induce rooting. After 20 days, regenerated plants with 3-4 root systems were obtained. Conclusion This approach provides high quality seedlings for artificial reddening.
