(Dendranthema grandiflorum L.)
belongs to Asteraceae family and commonly farmed all around the world today (Dole
and Wilkins, 2004; Hashemi et al., 2013) and ranked as the second most
economically important cut flower after rose (Kafi and Ghahsareh, 2009). Studies
on postharvest life of chrysanthemum cut flowers have shown to have long vaselife
by 8-10 days longer because it is not sensitive to ethylene. However,
water stress as a result of vascular occlusion has been reported as an
important factor in reducing the quality of chrysanthemum cut flowers (Halevy
and Mayak, 1979; Adachi et al., 1999; Nabigol et al., 2005) and the
formation of air embolism within the stems prevents nutrient and water
transport in vascular system which will ultimately result in increased
hydraulic resistance and water stress of chrysanthemum cut flower.
flowers vaselife is mainly affected by two factors, namely ethylene and microorganisms.
Ethylene accelerates the senescence of multiple flowers and microorganisms cause
by vascular blockage and thus result to reduce the vaselife of cut flowers (Van
Doorn, 1994, Zencirkiran, 2005; Zencirkiran, 2010).
The active solution 1-methylcyclopropene
(MCP), preservative for flowers is used to retain freshness of fresh cut
flowers (Asil et.al.,
2013). It can prevent
the aging of fresh cut flowers caused by ethylene, controlling its wither and bloom
before maturity, decrease the browning, yellowing and dropping of flower and leaves.
Especially, it can slow down the aging reaction of fresh cut flowers when there
is trace ethylene in the storage, transportation and sale
environment which extend the life of fresh cut flowers.
other hand, Chrysal CVBN neutralizes the damaging effect of daffodil slime in
mixed bouquets (Hunter, 2004), an easy-to-use stable tablet that dissolves quickly and produces clear and
odorless water, a conditioner for cut flowers used by growers, bouquet makers or
florists. Not harmful to flowers and maintains a good quality of leaves and
provides nutritional supplements to the flower for optimum bloom and a long vaselife
for the consumer (Services: Private label design, FAQ and care information). In
some cases, the lifespan even doubles. The use of these products creates an
added value for the entire horticultural chain: from grower to retailer to
consumer (Wiegel, 2012).
addition of cut flower food, Molasses or sugar continues to feed flowers after
they are cut, helping unopened buds to open and extending the life and vitality
of open flowers (Prince,
1988) molasses is a viscous by-product of refining
sugarcane or sugar beets into sugar. It varies by amount of sugar, method of
extraction, and age of plant. Sugar feed is the most important addition to any
homemade plant food. The lower pH does help the flowers absorb more water, but
more importantly, the acidified water creates a hostile environment for
microbes. Microbes, fed on decaying plant material and especially at any sugar added
base. Tap water is usually about neutral at 7.0, and for cut flowers it is best
to bring pH down to 3.5 or 4.0 (Tayama et.al., 1988).
