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.
