Speaking of many cuts the flower,
exposes can have the symptom in the ethylene gas which the flowers fading speed
speeds up and withers, reduces the market value.These questions may borrow the
use ethylene inhibitor to reduce its harm, Including the use ethylene
synthesizes inhibitor AVC and AOA as well as ethylene competition inhibitor
STS.New development ethylene competition inhibitor 1-MCP,Is one kind of
non-toxic synthesis gas, is easy to use in the fumigation processes on.
The partial types cut flower in 20 ℃
under, the use density 10-20 ppb 1-MCP fumigation 6-12 hours, might avoid it
receiving the ethylene the injury, the type have included
dianthus,snapdragon,calyx canthus.However,Use alone 1- MCP only can provide the
short-term protection to certain varieties,For example calyx canthus,Therefore
possibly is unable to be suitable and matches in the long-term exportation
transportation sells the work.The repetition processes 1-MCP to be possible to
reply its protection effect,But in ships and the sale time can create
inconveniently actually.The recovery way is in ships process, Slowly
releases 1-MCP in the vessel to lengthen the resistance ethylene time.At present
had is cutt flower to ship the process to test sustainably releases 1-MCP also
elastic plastic sealed tube.
Exportation transport test
Some 2 batch carry on the transport
test the calyx canthus to transport to England from Australia,These calyx
canthus'stems are from the Australian Brisben's farm recovery and the
exportation,Its stem long prunes is 50cm and take 400g as a bunch,Soaks in kills
insect and sterilization solvent.Then these flower was laid aside in being
filled with the rain water in the pail,Sets at into 2 ℃ to refrigerate passes
the night.The first large stock of goods has used 12 cardboards wooden
crates,Takes the inside lining respectively by 1 news paper.The bouquet of
flowers is wrapped 2 layers,4 bunches of 1 layer.Lays aside 1 separately, 2 or 3
continues to release 1-MCP the pipe in paper box lower level bouquet of
flowers's above,Does not have the laying aside to continue to release the 1-MCP
pipe the paper box to take comparison group.
In second large stock
of goods,In 12 boxes is takes the inside lining by the low density polyethylene
plastic thin film or the newsprinting paper.After the packing good calyx canthus,
these boxes are divided into 2 groups,6 box still installed are continuing to
release 1-MCP the pipe,But other 6 box then have not put have any pipe.This 2
large stocks of goods ship from the farm by way of 107 hours arrive the English
London a laboratory.
After arrives English the
laboratory,All flowers all emigrate out of paper box and lay aside in pack the
deionized water in the pail,And moves to the room temperature 20 ℃, the relative
humidity 70% and has 12 hours illuminations every day the bottles put in life
test room.After 24 hours again absorbing water,Stochastically takes out 36
floral axes from each group to lay aside in is loaded with the deionized water
and in the 10ppm chloride ion vase.
Test result
The flowers are by in 20 ℃ under employ the 10ppm ethylene regarding the
ethylene sensitivity test, every day lays aside 12 hours conditions to carry on.
In ships in the process, continues from the pipe to release 1-MCP to the box in,
can effectively delay the ethylene to induce the flowers fading 5 day. On the
contrary, from box that did not place continuously releases the tube take out
the flowers died of old age in first day.Laid aside 3 pipes boxes is best for
all processing of flower protection effect.May effectively retard the fading
function which the ethylene creates,Extrapolated possibly is massive 1-MCP
causes it to compare the average in the box distribution.
No matter the inside lining is uses
the plastic membrane perhaps or the news uses the paper, 1-MCP continued the
release regarding the Chimonathus Praecox which shipped by the paper box all to
provide the suitable degree protection. Compares with comparison group, does not
have the ethylene in the shipping environment in the situation, continues to
release 1-MCP not to be able to lengthen the bottle put life. Therefore, 1-MCP
continues the release to apply after preventing ships exposes under the ethylene
condition most can display the effect.
However in the for sale abroad
process, in the paper box lays aside the pipe and is unable to reduce because
the artificial operation to create the flower bud and the flowers falls off.
Furthermore, the use plastic film for the inside lining box to carries on
the transportation, Its flower bud and the flowers fall the probability to use
the newsprinting paper to be high 50-67%,Possible reason for flower bud and
blossom before 1- MCP form the valid density have already shed off namely.
Continues to release 1-MCP and
independent employment 1-MCP and comparison of the STS processing.
In an attachment experiment,
Chimonathus Praecox's stem lays aside after pick in is filled with the rain
water in the pail.Part lays aside in joining density 790ppb 1-MCP in the
airtight freezer storage,Other then lays aside in 2 ℃ under and includes the
0.2mM silver ion to compel in the imbibition 14 hours.Then again lays aside
these flower bouquets in the hard paper box.Other not has processed with 1-MCP
or STS the flower bouquet then takes contrapose group,The part joins 3 pipe to
continue to release 1-MCP,Each box has 8 bunches of bouquets of flowers,After
seals the box namely transports to London from the farm.
In 20 ℃ under, continues to
release 1-MCP the processing to be able to protect the floral axis to avoid
because the ethylene producing it after the transportation to fall the flower to
reach for 3 days long time.Relative under, independent employment 1-MCP
fumigation processing and STS processing then only can lengthen the flowers to
fall separately 1 and 2 days.Therefore 1-MCP continues the effect which releases
processes to be obviously good.
However，In front of for sale abroad by 1-MCP gas fumigation Chimonathus
Praecox bouquet of flowers，The effect in prevented the flower bud and the
flowers fall in exportation processing,Obviously good than continues to release
1-MCP or STS processes.In the for sale abroad process 1-MCP fumigation
processing cannot prevent the flowers fall off but can remarkably reduce the
quantity actually which the flowers falls.In all processing method,The flowers
fall the main reason all creates for the transportation process in physical
collision.The bouquet flowers that in continues to release 1-MCP processing
possibly in the transportation initial period,In the paper box the 1-MCP gas not
yet achieves in front of the enough density,On already suffered with the
ethylene correlation to flowers falls off, but STS then is unable completely in
ships in the process to prevent the flowers fall off.
This unexpectedly result completely and the formerly findings were
contradictory,Before STS by the proof is one kind of strong ethylene
inhibitor.Moreover, this result pointed out in compels attracts processing
only then the few silvers ion to absorption by flower.Very possibly very much
flower in the business processing to place in in bucket of fill the aqua of STS
at the same time,but is unable to absorb the enough silver ion.
Conclusion
Ships in processing in the
Chimonathus Praecox packing, penetrates the PVC tube continually to release
1-MCP to provide a substitution way substitution to use the 1-MCP processing
many times, and has provided a best anti-ethylene ability after the exportation.
This research describes and appraised 1-MCP which continue to release the system
pattern, may let cultivate entrepreneur and transport entrepreneur easily to use
for to protect they cutflower.The further will let 1-MCP continue release equip
to be able stably to release the 1-MCP gas is the future research
emphasis,Specially can avoid be threaten ethylene in the transportation initial
period protection flowers.In this transition period，The suggestion may process
through the transportation before 1-MCP fumigation and match continues to
release the 1-MCP processing，Causes cutflower after transportation period and
transportation not ethylene influence.
