Abstract:

Using stem segments of Sabina chinensis scale leaves and needle leaves as explants,the effects of different disinfection treatments,culture media,anti-browning agents,and plant hormone ratio on stem segment proliferation and rooting were investigated. The results showed that the optimal disinfection time of 0.1% HgCl2 for scale leaves and needle leaves was 18 and 16 min,and the pollution rate was 8.52% and 2.51%,respectively. Adding 1.0 mg · L-1 and 2.0 mg · L-1 PVP to the medium was suitable for anti-browning of scale leaves and needle leaves,respectively. The optimal primary culture medium for scale leaves was DCR + 2.0 mg · L-1 6-BA + 0.5 mg · L-1 NAA + 1.0 mg · L-1 PVP,with a bud induction rate of 83.27%,while for needle leaves was DCR + 2.0 mg · L-1 6-BA + 0.1 mg · L-1 NAA + 2.0 mg · L-1 PVP,with a bud induction rate of 89.35%. The optimal proliferation medium for scale leaves was DCR + 3.0 mg · L-1 6-BA + 0.5 mg · L-1 Trans-ZT + 0.5 mg · L-1 NAA + 1.0 mg · L-1 PVP,with a proliferation rate of 88.93%,while for needle leaves,it was DCR + 3.0 mg · L-1 6-BA + 0.1 mg · L-1 Trans-ZT + 0.1 mg · L-1 NAA + 2.0 mg · L-1 PVP,with a proliferation rate of 93.42%. The optimal rooting medium for scale leaves was 1/2MS + 1.0 mg · L-1 NAA + 1.0 mg · L-1 IBA + 1.0 mg · L-1 PVP,with a rooting rate of 73.29%,while for needle leaves,it was DCR + 2.0 mg · L-1 IBA + 2.0 mg · L-1 PVP,with a rooting rate of 71.64%. The survival rates of scale leaves and needle leaves plants in the substrate with a volume ratio of peat to vermiculite of 11 was 76% and 60% respectively.
