- 摘要:
- 为探索星点木组培微枝瓶外生根繁殖技术,以星点木组培微枝为试验材料,研究了不同植物生长调节剂种类、浓度对星点木组培微枝试管外扦插生根的影响。结果表明:星点木组培微枝试管外扦插生根率较高,生长调节剂能很好地促进生根;激素种类显著或极显著地影响星点木的生根效果;而不同激素浓度仅对平均侧根长和侧根数差异达到极显著水平,对总根长、偏根率及生根率差异不显著。应用隶属函数法综合评选出以浓度为50 mg·L-1 IBA处理微枝对生根效果最好。
- Abstract:
- In order to explore the bub outside tube of tissue culture plantlets of Dracaena godseffiana propagation technology,using tissue culture plantlets of Dracaena godseffiana as tested materials,the effect of different kinds and concentrations of plant growth regulators on tissue culture plantlets rooting of Dracaena godseffiana was studied.The results showed that plant growth regulators could promote rooting well.The rooting effect of the cuttings were significant among plant growth regulators(P<0.01).The average only differences in lateral root length and number of lateral root were significant among concentration of plant growth regulators(P<0.01) and the total root length,partial root rate and rooting rate difference was not significant.A comprehensive evaluation on cuttage rooting of plant growth regulators on tissue culture plantlets of Dracaena godseffiana was given based an subordinate function values analysis.The 50 mg·L-1 IBA had the best rooting effect.
