Vase life

• The use of proper preservative solution throughout the period of post-harvest handing is very important to prolong the life of cut flowers.
• Dipping of the stem for a very short period (5 seconds) in 1200-4800 ppm silver nitrate or soaking the stems in 1000 ppm silver nitrate for 10 minutes.
• Addition of 2 % sucrose to silver nitrate was found beneficial.
• It increased the vase-life from 12 days to 20 days.
