Abstract: As an important economic species, Toxicodendron vernicifluum could be propagated by the way of plant tissue culture. In order to solve the contamination, nystatin, amphotericin B, benzalkonium chloride, 75% ethanol and 0.1% mercuric chloride were used. Besides, cysteine, MS and White medium were used to solve browning. SPSS 12.0 statistical software was used for the single factor analysis of variance and Duncan's new multiple comparison analysis. By counting contamination rate, browning rate and survival rate, the best method of disinfection was 75% ethanol soaked 1 min, 1% benzalkonium soak 1 min, 0.1% mercuric chloride for 20 min, and the contamination rate was 1.15% . The best optimum medium was White culture mixed with 100 mg/L cysteine, and the browning rate was 1.15%. The survival rate was improved to 97.67%. The efficient and stable sterile system of Toxicodendron vernicifluum had been laid a solid foundation for the whole tissue culture system.
