Abstract:
OBJECTIVETo study the influecnce of gentian leaf blight on the output and quality of rough gentian.
METHODThe 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.
RESULTThe output 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.
CONCLUSIONThe 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.
