Abstract:Microrhizome of Zingiber officinale Rosc. cv. Jiushan were inducted from tube plantlets, which were derived from explant of stem tip, cultured on MS medium supplemented with 0.2 mg L-1 BA and varying concentrations of combinations of sucrose, NAA, Ca3（PO4）2, Paclobutrazol （Pac）. The results showed that rhizome production was best in tube culture on MS medium supplemented with 0.2 mg L-1 6-BA, 0.5 mg L-1 NAA, 2.5 mg L-1 Ca3 (PO4)2, 2.5 mg L-1 Paclobutrazol and 8% sucrose. NAA and 6-BA had no promotion effects on rhizome induction. More illumination stimulatory rhizome growth of the ginger.[
