摘要(Abstract):

目的 :研究龙胆斑枯病对龙胆产量及龙胆质量的影响。方法 :采用同一等级龙胆种苗移栽 ,秋季调查每株病情 ,测定产量 ,采用HPLC法测定龙胆苦苷类成分含量。结果 :产量随病情加重而下降 ,在病情指数大于 6 0时 ,产量下降明显 ,龙胆苦苷类成分含量在病情指数大于 70时开始下降。结论 :龙胆斑枯病病情较重时才造成较大产量损失和质量下降 ,龙胆斑枯病病情指数小于 6 0时对龙胆生产造成损失很小
Objective: To study the influecnce of gentian leaf blight on the output and quality of rough gentian. Method: The same grade seedlings were transplanted, disease of every plant was investigated in autumn and the output of gentian was determined. HPLC was applied to determine the content of gentiopicroside and swertiamarin. Result: The ouptut decreased with the aggravation of the disease, and the decrease was obvious when the index of disease was above 60. The content of gentiopicroside and swertiamarin began to drop when the index of disease was above 70. Conclusion: The loss of output and the drop of quality are relatively heavy when the disease is serious. The loss of income is not obvious when the index of disease is under 60.
