Post-harvesting longevity
of pseudo-bulbs storing Dendrobium nobile
(Orchidaceae) flowers.
Orchids are considered ornamental plants of
great importance in the flowers market, being used
as poted plants or cut flower. The objective of this
work was to evaluate the postharvest longevity of
pseudo-bulbs of Dendrobium nobile wistli flowers,
using preservant solutions with different concentrations
of sucrose. Treatments used were as follows:
T1) distilled water; T2) no water; T3) 10gL-1 of sucrose;
T4) 20gL-1 of sucrose; T5) 30gL-1 of sucrose;
T6) 40gL-1 of sucrose and T7) 80gL-1 of sucrose.
Longevity was evaluated by a grading criteria. The
experimental design was entirely casualized, with
seven treatments and ten replications. Flower durability
was ten days and longevity was not influenced
by the preservant solutions containing sacharosis.
