星点木组培苗移栽技术研究

目的]研究星点木组培苗的移栽技术。方法]研究移栽前不同炼苗处理、移栽基质和移栽措施对星点木组培苗移栽的影响。结果]将星点木组培苗先在温室内闭瓶锻炼3 d,再打开瓶锻炼2 d后的移栽效果较好,成活率达94.44%;以泥炭土∶珍珠岩(V/V)=1∶1为移栽基质时移栽效果较好,成活率达96.67%,平均抽生高度达2.04 cm;移栽前对移栽基质进行800倍多菌灵稀释液灭菌,移栽后盖膜的移栽效果较好,成活率达95.24%。结论]该研究为星点木苗木的商业化生产提供了有力支持。

Study on Transplanting Technology of Tissue Culture Seedlings of Dracaena godseffiana

Objective] The paper was to study the transplanting technology of tissue culture seedlings of Dracaena godseffiana. Method ] The effects of different pre-treatments, different transplanting substrate and different transplanting treatments on transplant of tissue culture seedlings of D. godseffiana were studied. Result] The transplanting effect was better when the culture seedlings of Do god~effiana were pre- treatmented with caps in the greenhouse for 3 days and was uncapped for 2 days before transplanting, then the survival rate was 94.44% ; the transplanting effect was better when the transplanting substrate was peat soil ： perlite （V/V） = 1 ： 1, and the survival rate was 96.67% with the average height for 2.04 cm ; the transplanting effect was better when the transplanting substrate was sterilized by 800 times of carbendazim dilu- tion liquid and the seedlings were covered by membrane after transplanting, then the survival rate reached 95.24%. Conclusion] The study provided strong support for the commercial production of D. godseffiana seedlings.
