| 摘 要： | 以Nubiana叶片为试材,对其愈伤组织的诱导、继代培养及褐变调控进行了研究。结果表明:Nubiana叶片愈伤的诱导及继代培养以WPM附加BA 0.5 mg/L和2.4-D 2.0 mg/L的培养基上效果最好;0.1%的柠檬酸(CA)具有明显地促进愈伤组织生长、抑制褐变的作用,而聚乙烯吡咯烷酮(PVP)的效果最差;3%的葡萄糖(Glu)最适于愈伤组织的诱导及继代。综合以上研究结果,获得较好的愈伤组织的适宜培养条件是:WPM BA 0.5 mg/L 2,4-D 2.0 mg/L Glu 3% CA 0.075%~0.1%,暗培养28~30 d。

| Abstract: | The inducing,subculture,and control browning of callus in leaves of Nubiana were studied in order to establish the optimum condition of inducing and growth of callus.The results showed that WPM medium supplemented with BA 0.5 mg/L and 2,4-D 2.0 mg/L was the best medium for the inducing and subculture of callus;0.1% of citric acid(CA) had remarkable results of promoting the growth and controlling the browning of callus,while the PVP showed the worst result;3%~5% of glucose was the best carbon source of inducing and subculture of callus.It can be concluded that the suitable culture condition to produce a high mass was WPM medium supplemented with BA 0.5 mg/L,2,4-D 2.0 mg/L,glucose 3% and CA 0.075%~ 0.100% for 28~30 days in darkness. |
