以萼距花为试材,分别研究不同浓度的NAA、IAA和不同基质对扦插繁殖的影响,在单因素试验基础上采用正交实验优化条件。结果表明:生根条件分别为NAA浓度150mg/L、IAA浓度250mg/L、基质为园土时生根效果最好;萼距花扦插繁殖的最佳条件为基质园土,IAA浓度250mg/L,NAA浓度100mg/L。
Taking Cuphea hookeriana Walp as research materials, effect of different concentrations of NAA, IAA and different medium type on cuttings rooting were studied with orthogonal test based on single-factor test. The results showed that,the effect of treatment with 150 mg/L NAA or 250 mg/L IAA was the best for the rooting efficiency respectively,and cutting in garden soil had a better rooting effect than in other substrates; the cutting rooting of C. hookeriana with treatmented by 250 mg/L IAA and 100 mg/L NAA in garden soil was the best.
