Commercial Floriculture

Inherent factors influencing post-harvest life of flowers

• Keeping quality of flowers vary from species and cultivars, this may be due to genetic or inherent factors like differences in anatomical, physiological, physical, biochemical and genetic make up.
  
• Keeping quality also depends on

  • Carbohydrate reserves,
    
  • Osmotic concentration,
    
  • Pressure potential of petal cells,
  • Stomatal functioning,
    
  • Difference in number of thick walled supporting cells in the xylem element and phloem fibre,
    
  • Presence or absence of a complete ring of secondary thickening in flower peduncles,
    
  • Differences in the diffusive resistance of leaves in the field.
    
  • Lignifications,
  • Level of plant hormones and
  • Susceptibility to disease and insects.
