Result and analysis
Tupe is to the influence of cut-flower water content
Fig. 1, Fig. 2 show: no matter be under normal temperature or the refrigeration storing, crane hopes the percentage of water loss of blue cut-flower all increase progressively along with the increase of storing fate, and is extremely significant correlation (under 25 ℃: rCK1=0.979**, rA=0.977**, rB=0.975**, rA-2=0.974**; Under 12 ℃: rCK2=0.970**, rC=0.971**, rD=0.977**, rC-2=0.978**).Each handles increase progressively (except the C-2 the 10th day) that has suppressed percentage of water loss to some extent 1-MCP.
Under the normal temperature (Fig. 1), it is minimum to repeat the stifling percentage of water loss of handling, and 6h, 24h handle and take second place, and CK is the highest.Store and transport the 4th, 10 day, repeat stifling processing and 6h processing and contrast and all reach utmost point significant difference; Wherein repeat stifling the processing and handle well than 6h, the two reaches significant difference.
Refrigeration is (Fig. 2) down, stores and transports 4-8 days, and the inhibition that 6h handles is best, and all the other are that 24h handles, repeats stifling the processing successively, and CK is the poorest; Store and transport the 10th day and repeat the stifling percentage of water loss of handling on the contrary greater than CK; Statistical analysis stores and transports the 4th, 10 day result and shows: all reach extremely significant difference between each is handled.Above result shows that the refrigeration storing should not repeat to fumigate.Store and transport the 2nd day and respectively handle percentage of water loss and negative value occurs, may still to be in the after-ripening stage relevant with refrigeration initial stage dehydration cut-flower slow and freshly harvested.
The differences that compare between each is handled under two kinds of storing temperature show: except repeating stifling processing, in identical tupe and storing fate, percentage of water loss that refrigeration is respectively handled is down wherein handled minimum all less than under the normal temperature with 6h.
Tupe is to the influence of acetate releasing quantity
Table 1 shows: under the normal temperature, the acetate releasing quantity that 1-MCP three handles all is subjected to the utmost point to be suppressed significantly; Wherein, 6h handles and to repeat the stifling acetate releasing quantity of handling less, and handles with 24h and to reach significant difference.
(25 ℃) different disposal pattern is hoped the physiological influence of blue cut-flower to crane under table 1 normal temperature
Under the refrigeration, each is handled acetate releasing quantity and is (seeing Table 2) to big order from childhood: 6h processing＜24h handles＜repeats stifling processing＜CK.Wherein, 6h, 24h handle and all reach utmost point significant difference with CK, also are remarkable difference between the two, but it is not remarkable with the difference of CK to repeat stifling processing.
Relatively under two kinds of storing temperature between the same treatment pattern difference of acetate releasing quantity show: except repeating stifling the processing, down the acetate releasing quantity of each tupe is all less than the acetate releasing quantity of same treatment pattern under the normal temperature in refrigeration, and the acetate releasing quantity of handling with 6h is minimum.
Table 2 refrigeration (12 ℃) different disposal pattern is down hoped the physiological influence of blue cut-flower to crane
Tupe is to the influence of the relative membrane permeability of petal
Under the normal temperature (table 1), through 1-MCP stifling three handle the relative membrane permeability of petals all the utmost point reduce significantly, it is minimum wherein to repeat the stifling relative membrane permeability of handling of petal, secondly is that 6h handles, 24h handles higher relatively, and each all reaches utmost point significant difference between handling.Refrigeration is (table 2) down, through 1-MCP stifling three handle the relative membrane permeability of petals equally all the utmost point reduce significantly, but that the three relative membrane permeabilities of handling of petal are handled with 6h is minimum, secondly is that 24h handles, it is higher relatively to repeat stifling processing, and each also all reaches utmost point significant difference between handling.Under two kinds of storing temperature between the same treatment pattern difference of the relative membrane permeability of petal be: except repeating stifling the processing, the refrigeration relative membrane permeability of each tupe down and is handled minimum with 6h all less than the relative membrane permeability of same treatment pattern under the normal temperature.
Tupe is to the influence of petal anthocyan
No matter be under normal temperature (table 1) or refrigeration (table 2) storing, 1-MCP three handles and all reduces the content that crane is hoped orchid lobe anthocyan to some extent.But repeat stifling processing and 6h processing and contrast under the normal temperature storing reach the significant difference, and all the other each action effects of handling are not remarkable.Relatively under two kinds of storing temperature between the same treatment pattern difference of petal anthocyanidin content show: refrigeration down the anthocyanidin content of each tupe all less than the anthocyanidin content of same treatment pattern under the normal temperature.
The flowers are in blossom puts the influence of rate to inferior for tupe
Table 1 shows: under the normal temperature, 1-MCP respectively handles equal utmost points and promotes crane to hope the opening of blue the 2nd, the 3rd Xiao Hua (i.e. time flower) significantly, and each size order of handling that time the flowers are in blossom and putting rate is: 6h processing＞24h handles＞repeats and fumigates processing＞CK.Wherein, the open rate that 6h handles time flower increases by 16.9 (35.8%) than contrast, and its action effect and other two kinds of storing patterns also reach extremely significant difference.Table 2 shows: refrigeration down, each size order of handling that time the flowers are in blossom and putting rate is: 6h processings＞24h processings＞CK＞repeat stifling the processing respectively reaches utmost point significant difference between processing.Wherein, 6h and 24h handle the opening that the utmost point promotes the 2nd, the 3rd Xiao Hua significantly, and especially 6h handles, and secondly the open rate of flower increases by 23.9 (64.0%) than contrast; Suppress time opening of flower significantly and repeat the stifling utmost point of handling.The difference that relatively time the flowers are in blossom between the same treatment pattern under two kinds of storing temperature puts rate shows: the normal temperature storing down the same treatment pattern time the flowers are in blossom puts rate all greater than the refrigeration storing, show that low temperature has suppressed the opening of inferior flower.
Tupe is to inferior influence of spending fresh-keeping rate
Under the normal temperature (table 1), each tupe of the 1-MCP all utmost point improves time fresh-keeping rate of flower significantly, and each processing is inferior spends the size order of fresh-keeping rate to be: 6h handles＞repeat stifling processing＞24h processing＞CK, and wherein 6h handles than contrasting and exceeds 42.1 (167.7%).Between handling, each reaches extremely significant difference.Refrigeration is (table 2) down, each processing is inferior spends the size order of fresh-keeping rate to be: 6h processing＞24h processing＞CK＞repeat to fumigate and handle, wherein, 6h and 24h handle equal utmost points and improve time fresh-keeping rate of flower significantly, reduce time fresh-keeping rate of flower significantly and repeat the stifling utmost point of handling.
Relatively time spend the difference of fresh-keeping rate to show between the same treatment pattern under two kinds of storing temperature: the refrigeration storing down, 6h handles, 24h handles and contrast time spend fresh-keeping rate all to be higher than the normal temperature storing, be lower than the normal temperature storing on the contrary and repeat stifling processing.The highest with the stifling fresh-keeping rate of 6h under the refrigeration storing in all tupes under two kinds of storing temperature, reach 83.6%; Contrast under the normal temperature minimum (25.1%).Illustrate that the refrigeration storing is conducive to the fresh-keeping of time flower, and stifling inferior flower is produced of repeating that refrigerates under the storing injured.
To sum up:
Crane is hoped blue suitable storing temperature: under two kinds of storing temperature between the same treatment pattern difference of every physiological metabolism index be: except repeating stifling the processing, refrigeration storing cut-flower percentage of water loss, acetate releasing quantity, the petal membrane permeability of all the other processing down all stores and transports less than normal temperature; Inferiorly spend fresh-keeping rate then to store and transport greater than normal temperature.The refrigeration storing petal anthocyan of all processing down all stores and transports less than normal temperature.Above result shows: low temperature storing and transporting is conducive to crane and hopes the fresh-keeping of blue cut-flower.But under the low temperature, each handle time the flowers are in blossom that the rate of putting all stores and transports less than normal temperature.
The crane of 1-MCP is hoped the blue suitable treatment time: no matter be under normal temperature or the refrigeration storing, cut-flower percentage of water loss, acetate releasing quantity, petal membrane permeability, petal anthocyan that different time is handled are 6h processing＜24h processing＜CK, and inferior the flowers are in blossom puts rate and fresh-keeping rate is 6h processing＞24h processing＞CK.Wherein, acetate releasing quantity two is handled with contrast and is reached utmost point significant difference, and the two reaches significant difference; The petal membrane permeability, inferior the flowers are in blossom puts rate and fresh-keeping rate each all reaches utmost point significant difference between handling; Show that two kinds of fumigation times all are conducive to the opening that crane is hoped the fresh-keeping and inferior flower of blue cut-flower, and best with the stifling treatment effect of 6h.
Repeat whether to fumigate: refrigeration down, repeating stifling every physical signs of handling all handles not as good as 6h is stifling, open rate and the fresh-keeping rate of therein ethylene burst size, petal membrane permeability, inferior flower all reach utmost point significant difference, the open rate of inferior flower and fresh-keeping rate even also poorer than contrast illustrate: should not repeat to fumigate under the refrigeration storing.Under the normal temperature, although repeating physiological metabolism indexs such as the stifling cut-flower percentage of water loss of handling, acetate releasing quantity, petal membrane permeability, petal anthocyan all handles less than 6h is stifling, but the open rate of inferior flower and fresh-keeping rate are handled not as good as 6h is stifling, illustrate: normal temperature storing crane down hopes suitable repetition of blue cut-flower fumigate processing, but effect is undesirable.As seen, crane hopes blue cut-flower not need to repeat stifling the processing.
In the sensitive difference comparison sheet 1 of physiological metabolism index, the table 2 each physiological metabolism index of handling to the stifling susceptibility of handling of 2 μ L/L1-MCP namely each handle with the situation that departs from of contrast as can be known: departure degree greater than 50% index acetate releasing quantity, relative membrane permeability are arranged, inferior the flowers are in blossom puts rate and inferiorly spend fresh-keeping rate, wherein inferiorly spends fresh-keeping rate even greater than 100%; And the departure degree of anthocyan is lower, is least responsive physiological metabolism index.
To sum up analyze as can be known: the crane of 2 μ L/L1-MCP hopes that the suitable stifling pattern of blue fresh cut-flowers storage fresh-keeping is refrigeration storing (12 ℃) the stifling processing of 6h down.And stifling processing of 6h is economical and effective pattern easily under the normal temperature.
Hope that with crane blue fresh cut-flowers is test material, pluck open the 1st Xiao Hua and spray healthy and strong spray of the same size of the same day, be sent to laboratory (25 ℃), it is isometric that arrangement back water is cut 50cm, after 24h rehydration (running water) cooling, by the requirement of fresh cut-flowers outlet storing, per 1 pricks 10 flower packings, the flower place puts the cup-shaped plastic foil, and incision is wrapped moisture sponge.Rehydration, handle all in climatic cabinate (25 ℃, 75% relative moisture) and carry out.The peace happiness training that 1-MCP reagent adopts Taiwan sharp system company to produce
Test is carried out under room temperature (25 ℃) and refrigeration (12 ℃) two kinds of temperature simultaneously, and 1-MCP arranges six concentration of 0 (CK), 0.2,1,2,4,8ul/L and handles.Volume with the aviation storing and transporting box is that unit calculates the requirement that each concentration is handled peace happiness training, each concentration is handled required An Xipei divides equally, put into aviation storing and transporting box two that bouquet is housed immediately after soaking into distilled water, each repeats an independent case, seal all slits of each aviation storing and transporting box in case the 1-MCP gas leak with adhesive tape at once, take out peace happiness training behind the 6h, each handles simulation aviation storing research under corresponding treatment temperature.Each is handled and repeats 6 times, separated into two parts, and a part is used for the tracking and testing of cut-flower weight-loss ratio, and another part is used for the observation of the 1st every physiological index determining of Xiao Hua and the 2nd, the 3rd Xiao Hua (i.e. time flower) open rate and fresh-keeping rate.
