Abstract

Abstract: Using three different genotypes of shoot sections of mature superior clones of Cunninghamia lanceolata, the effect of factors such as plant growth regulators(PGRs), genotypes, basal medium and activated charcoal were studied for rooting frequency. The results showed that genotypes and NAA were key factors influencing rooting efficiency. Genotype 1# was more capable of rooting. The basal medium 1/4 DCR added with IBA 1.0 mg/L or NAA 0.5-1.0 mg/L could increase rooting efficiency to the level of 90%. Genotype 2# had a weaker ability of rooting. The 1/2DCR basal medium added with IBA 1.5 mg/L or NAA 1.0 mg/L was better in adventitious roots induction for this genotype. For genotype 3#, it had the best rooting efficiency when the level of IBA was 1.5 mg/L or the level of NAA was 1.0 mg/L, 3/4 DCR was fit for rooting. Addition of activated charcoal could not effectively improve rooting in this experiment.
