Sunflower postharvest longevity affected by silver nitrate and sucrose treatments.


The postharvest of sunflower inflorescences was evaluate by six treatments with sucrose (4 and 10%) or sucrose plus silver nitrate (10 and 20 mgL- 1) and the control (deionized water). The treatments, with three replications each, were distributed in a complete randomized block design with three inflorescences per replication. Longer longevity was reached by 4% sucrose that increased the vase life of the inflorescence by up to five days compared to the control. Silver nitrate associated with sucrose did not improve the longevity.
