[Method] The axillary bud explants of Qiantang No.5 were used as experimental material. Different concentrations of Qianxing No.1 were added in the media to determine the optimal bacteriostatic con- centrations of Qianxing No.1 for induction and proliferation culture of sugarcane in the open tissue culture. [Result] The results showed Qianxing No.1 with the con- centration of 0.5% could effectively inhibit the medium contamination. Under that bacteriostatic concentration, the surviving rate of explants was up to 80%, and the propagation coefficient was 3.1. [Conclusion] This research would provide a theoretic basis for the simplification of sugarcane tissue culture procedure and the reduction of production costs.展开更多
