摘要

摘要: 目的研究食用玫瑰烈火的组培快繁技术，建立组培快繁技术体系，解决烈火食用玫瑰种苗工厂化生产的瓶颈问题。方法通过对比试验，筛选外植体最佳的消毒药剂及处理时间组合；通过正交试验，筛选芽苗增殖培养最佳的植物生长调节剂种类及浓度水平，筛选最佳的生根基本培养基、植物生长调节剂种类及浓度水平。结果（1）食用玫瑰烈火的外植体消毒以0.1%HgCl₂ 处理8 min，外加6%次氯酸钠溶液处理3~6 min效果最佳；（2）芽苗增殖最优培养基配方为MS+6-BA 2.0 mg·L⁻¹ +NAA 0.2 mg·L⁻¹+ TDZ 0. 06 mg·L⁻¹，增殖系数达3.47；（3）芽苗生根最佳培养基为改良1/2MS+ NAA0.2 mg·L⁻¹+IBA0.01 mg·L⁻¹，生根率达89.44%，根系健壮。结论通过外植体消毒对比试验，芽增殖、生根培养正交试验所建立起的食用玫瑰烈火组培快繁技术体系，可为烈火食用玫瑰种苗工厂化生产提供技术支撑，促进食用玫瑰在农业上的推广应用。

Abstract: Objective To systematically study the tissue culture and rapid propagation technology of edible rose flaming fire, and establish the tissue culture and rapid propagation technology system to solve the bottleneck problem of seedling industrialized production of edible rose flaming fire. Methods The best disinfectant and treatment time of explants were selected through comparative test; Through orthogonal test, the best plant growth regulators and concentration levels were selected for bud proliferation culture, and the best rooting basic medium, and plant growth regulators and their concentrations were selected. Result (1) The explants treated with 0.1% HgCl₂ for 8 min and then 6% sodium hypochlorite solution for 3–6 min was the best for tissue cluture of flaming fire; (2) The optimum medium formula for bud propagation was MS+6-BA 2.0 mg·L^-1+NAA 0.2 mg·L^-1+TDZ 0.06 mg·L^-1, and the multiplication coefficient was 3.47; (3) The improved rooting medium for bud seedlings was 1/2MS+NAA 0.2 mg·L^-1+IBA 0.01 mg·L^-1, the rooting rate of which was 89.44%, and the root system was strong. Conclusion The tissue culture and rapid propagation technology system of edible rose flaming fire established by the comparative experiment for explant disinfection, and the orthogonal experiment for bud proliferationand rooting culture, can provide technical support for the industrialized production of edible rose seedlings of flaming fire, and promote the popularization and application of edible roses in agriculture.
