Longevity of Consolida ajacis inflorescences
influenced by pulsing with sucrose
and silver tiosulfate.
The present work had the objective to evaluate
the influence of silver tiosulfate (STS) in combination
or not with sucrose on Consolida ajacis inflorescence
vase life. The inflorescences were
standardised in length and flower opening and than
pulsed for 30, 60, 90 and 120 minutes in 5%, 10%,
15% and 20% sucrose or with 0.2, 0.4, 0.6, 0.8 and
1.0 mM STS, and the control treatments with distilled
water. In a second set of experiments the inflorescences
were pulsed with 0.2, 0.4, 0.6, 0.8 and 1.0
mM STS combined with 5% sucrose for 30 minutes.
Treatment with sucrose did not affect the vase life or
flower abscission, when compared with the control.
Pulsing the inflorescences with STS, in combination
or not with 5% sucrose, were effective in extending
the flower vase life and reducing flower abscission
and wilting. Pulsing the inflorescences with 1.0 mM
of STS mixed or not with 5% sucrose for 30 minutes
increased flower longevity from approximately 8
days (control) to about 15 days, and fell down the
abscission from 66.9% to values bellow to 17.5%.
