title: [Effects of spraying uniconazole on plant morphology and total alkaloid content of Aconitum carmichaeli].
abstract: OBJECTIVE
  To study the effects of spraying uniconazole on plant morphology and total alkaloid content of Aconitum carmichaeli for providing theory base for establishment of planting measure.
  
  
  METHODS
  The mainly morphological character and total alkaloid content of Radix Aconiti Lateralis Praeparata were studied under different uniconazole spraying time and density.
  
  
  RESULTS
  Unieonazole could decrease plant height and leaf area, increase stem diameter, leaves and fibril roots, and the amount of dry matter. The difference in total alkaloid was not significant.
  
  
  CONCLUSIONS
  In this experiment,Spraying uniconazole has no significant effect on total alkaloid content of Aconitum carmichaeli. It is better for increasing yield per plant to applied 120 mg/L unieonazole at sub-root enlargement stage than sub-root formation stage, and it is better to applied the same density at another stage for adjusting the plant morphology.
