RESUMEN
Object To develop a best approach for the rapid propagation of Lilium brownii F.E. Brown var. viridulum Baker by tissue culture. Methods Different parts of the bulb were tried as the explant and cultured on different culture media with the additon of different portions of various hormones at various cultural conditions. Results The best medium for the culture of explant bulb was MS+NAA 0.5 mg/L and GA 3 2.0 mg/L and the highest induction rate was at the lowest part of the scale leaves, which attained 92.5%. The small bud can further differentiate to form secondary small buds. By liquid-quivering culturing, the weight increase can be accelerated. Conclusion Tissue culture of L. brownii var. viridulum can achieve its rapid propagation, resulting in the possibility for its industrial production.
