摘　　要：以野生药食两用植物少花龙葵为材料,在室内水培条件下,研究了不同处理浓度萘乙酸(NAA)、插条类型及插条留叶方式对少花龙葵插条生根的影响。结果表明:在5～20 mg/LNAA处理下,诱导少花龙葵半叶嫩枝和半叶硬枝形成不定根的适宜浓度分别是5 mg/L和20mg/L;少花龙葵嫩枝和硬枝分别在其适宜NAA浓度处理下,均以缺叶插枝的生根效果为差;少花龙葵嫩枝在5 mg/L NAA处理下以全叶插枝的生根效果最好,生根率100%;少花龙葵硬枝在10 mg/L NAA处理下半叶与全叶插枝的生根效果较为一致,生根率均为96.67%。The effects of 5-20 mg/L NAA and different cutting types, retaining leaves ways on cutting propagation of wild medicinal and edible plant Solanum nigrum L. var. Pauciflorum Liou were studied in water culture under the controlled conditions. The results showed that the suitable NAA treatment concentration for rooting of half leaf browse was 5 mg/L,and 10 mg/L for rooting of half leaf hardwood. The rooting rat of without lamina browse was the lowest in the treatment of 5 mg/L of NAA compare to half leaf browse and whole lamina browse, the rooting rat of whole lamina browse was the highest compare to half leaf browse and without lamina browse, the rooting rat of whole lamina browse in the treatment of 5 mg/L of NAA was 100%. The rooting rat of without lamina hardwood was the lowest in the treatment of 10 mg/L of NAA compare to halfleaf hardwood and whole lamina hardwood, but the rooting rat of whole lamina hardwood and half leaf hardwood was equal, both the rooting rat of whole lamina hardwood and half leaf hardwood was 96.67%.
