Effect of exogenous ethylene on fresh weight loss
and vase life
The studied cut orchid hybrids had different weight losses
through day 1, 3 and 5 in vase solution, with D. Darren
Glory showing significantly highest weight loss compared
to other hybrids (Table 1). In addition, the main effect of
ethylene on weight loss of the orchids was significant
(Table 1), although comparison of weight losses between
exposed and non-exposed orchids to ethylene showed
that only D. ‘Shavin White’ had significantly higher weight
loss in flowers exposed to ethylene (Figure 1). Moreover,
the interaction between ethylene treatment and days in
vase solution was significant (p ≤ 0.05). Flowers exposed
to ethylene had constant weight loss until third day in
vase solution (Figure 2). After 3 days in vase solution,
flowers exposed to ethylene showed a quadratic increase
in weight loss and by 5 days in vase solution, the flowers
had 26% weight loss. However, there was no significant
