| 摘 要： | 以七彩千年木为试材,采用水培法经过不同浓度萘乙酸(NAA)处理,进行清水、遮黑扦插等条件诱导水生根系试验,筛选诱导水生根系的最佳NAA浓度,再进行不同营养液(清水、1/4MS、Hoagland溶液、KC营养液、必绿水溶性肥料)的培养试验.结果表明:采用低浓度NAA短时间(1 d)处理可促进根系生长,NAA最佳诱导浓度为1 mg/L.在供试营养液中,Hoagland溶液对促进七彩千年木的生长发育效果最好.

| Abstract: | In this paper Dracaena marginata was used as the test material to study the technology of hydroponic culture.With different concentration of NAA treatment to induce aquatic root system,the aim was to choose the best concentration of NAA.After the water-cultivated-root growed,different nutrient solutions(clear water,1/4MS,Hoagland solution,KC nutrition and watersoluble fertilizer) were used to culture the plantlet of Dracaena marginata in order to find suitable nutrient solutions to promote Dracaena marginat... |
