Abstract :
In order to improve the vase life of alstroemeria cut flowers
(Alstroemeria aurantiaca), an experiment was performed based on completely
randomized design with 10 treatments including cycloheximide (50, 100
and 200 mg l-1), benzyladenine (50, 100 and 200 mg l-1), coconut juice (5, 10
and 20 %) and control (distilled water) in three replications. In this study,
characteristics such as vase life, dry matter, increasing ° Brix, the percentage
of flower opening, chlorophyll a and b and ionic leakage were evaluated.
The results showed that coconut juice at a concentration of 5% has the
maximum vase life (17.39 days), although it has no significant difference
with different levels of benzyladenine and 10 and 20% coconut juice
treatments. 10% coconut juice with 2.58 and 0.88 has the highest ° Brix and
flower opening index, respectively. Treatments of 50 mg l-1 benzyladenine,
5 and 10% coconut juice had the maximum impact on the amount of dry
matter. The most successful treatments for reducing ionic leakage are two
treatments of 5% coconut juice and 100 mg l-1 benzyladenine. All treatments
cause maintenance of chlorophyll a and b compared to the control, and two
treatments of 50 mg l-1 cycloheximide and 5% coconut juice had the highest
content of chlorophyll a and b, respectively among treatments. According to
the obtained results, using 5% coconut juice in the vase solution can
effectively improve the vase life of alstroemeria cut flowers.
