菊花‘北甘菊’和‘神马’对除草剂草丁膦的敏感性研究

Sensitivities of Chrysanthemum lavandulifolium and Chrysanthemum Morifolium 'Shenma' to Herbicide Glufosinate

[目的]探究不同菊花品种对除草剂草丁膦的敏感性。[方法]以野生菊花‘北甘菊’和秋季切花菊‘神马’为材料,研究了菊花对除草剂草丁膦的敏感性表现。[结果]不同品种不同营养生长期的植株对草丁膦的敏感性不同,‘神马’植株平均叶片数为13叶片期时对草丁膦的敏感浓度为40 mg/L,‘甘菊’植株平均叶片数为8叶期时对草丁膦的敏感浓度为50 mg/L。[结论]为草丁膦抗性的转基因菊花的筛选提供了理论依据。

[ Objective] The aim was to explore sensitivities of different varieties of Chrysanthemum to herbicide glufosinate. [ Method] The sensitivities of wild Chrysanthemum lavandulifolium and autumn cut Chrysanthemum morifolium ＇ Shenma＇ to herbicide glufosinate were stud- ied. [ Result] The glufosinate sensitive concentration of Chrysanthemum changed with their vegetative growth phases and species. The sensitive concentration of Chrysanthemum morifolium＇ Shenma＇ to glufosinate was 40 mg/L at 13-leaf stage, while the sensitive concentration of Chrys- anthemum lavandulifolium to glufosinate was 50 mg/L at 8-leaf stage. [ Conclusion] The research result provides theoretical for the screening of transgenic Chrysanthemum with resistance to glufosinate.
