| Abstract:
Longevity (vase life) of 'White Sim' carnation cut flowers was measured monthly for one year. Five conditioning treatments were compared: control (water only); 10 minute stem emersion in 1000 ppm AgNO3; Ag emersion plus 10 or 25% sugar for 24 hrs; and 25 ppm AgNO3 plus 4% sugar continuously. Longevity in days of the control and continuous Ag plus sugar were 6–7 and 15–18 days, respectively. Neither treatment showed a distinct seasonal trend. The Ag emersion only increased longevity by 3 days over the control throughout the year. Ag emersion plus 25% sugar for 24 hours increased longevity over the Ag emersion by only 3 days during fall and winter but only 1.5 days during spring and summer. The 10% sugar treatment for 24 hrs did not give a consistent increase over Ag emersion only. | |
