Description
Technical field
The present invention relates to clove leaf honeysuckle aseptic and rapid propagation method.
Background technology
Clove leaf honeysuckle is Beijing two level endangered plants, and record has 7 plants, but rarely seen one plant in the range of the administrative region of a city of Beijing.
In order to save the endangered plants, its population at individual quantity should be expanded first, but never collect seed for many years, only
A number of individual plant can be obtained by groping the means of tissue-culturing rapid propagation, and utilize the clove leaf honeysuckle quick breeding technology established
Periphery provinces and regions introduces a collection is bred, then together wild environment is arrived in cultivation again with Beijing introduces a collection, realizes that clove leaf is born
The field in winter returns.However, it is extremely difficult to establish clove leaf honeysuckle sterile rapid propagation system.
Thus, effective clove leaf honeysuckle sterile rapid propagation system is established, it is significant.
The content of the invention
The present invention is the following discovery based on inventor and completed:
It is extremely difficult to establish clove leaf honeysuckle sterile rapid propagation system, has perhaps in the first step to explant seeded process
More problems need to solve.The fast numerous the most frequently used explant of breeding, rare or endangered species is stem-segment with single bud, but clove leaf honeysuckle explant
After stem-segment with single bud inoculation, either pollute or be sterilized liquid kill, a variety of thimerosals, more concentration gradients coordinate explant sterilization
Experiment finds that clove leaf honeysuckle stem-segment with single bud contains endophyte, and is endogenetic fungus, result in the failure of explant introducing;
If using blade as explant, although sterile system can be established, inducing clumping bud rate is extremely low, and the probability that makes a variation may
It is larger, it is impossible to the effective way quickly bred as clove leaf honeysuckle.
It is contemplated that at least solves one of technical problem present in prior art.Therefore, one object of the present invention
It is to propose that one kind being capable of effective clove leaf honeysuckle aseptic and rapid propagation method.
According to an aspect of the present invention, the invention provides a kind of clove leaf honeysuckle rapid propagation method.According to this hair
Bright embodiment, this method comprise the following steps:
(1) explant is prepared:The clove leaf honeysuckle sprout with micro xylem is taken, perula is peeled off using single-edge blade, with
Petiole is quickly removed from base portion afterwards, continues to peel off base portion perula;After perula is fully exfoliated, then extend to branch skin zone,
Branch epidermis around bastem portion is all stripped clean, retains a little light green forming layer;The edge of a knife is slightly tilted, in bastem portion
Under each knife, pay attention to never cutting through xylem, sprout base portion gently chosen with point of a knife, carry bud and be no more than thick wooden of 0.5mm
Portion, as explant;
(2) sterilize:In super-clean bench, 10% is filled with the explant that cutting obtains being moved to by autoclaved tweezers
Fresh hydrogenperoxide steam generator triangular flask in, instill 3-5 drop Tween-60s, concussion 12 minutes, it is molten then to pour out hydrogen peroxide
Liquid, and with aseptic water washing explant, drain away the water, prepare inoculation;
(3) it is inoculated with:The explant by sterilization is moved to from the triangular flask rapidly and fills the training for starting proliferated culture medium
Support in bottle and carry out closing culture, the wherein xylem of sprout base portion will be completely immersed in culture medium;
(4) after the explant in the blake bottle bears Multiple Buds, the Multiple Buds are transferred in root media
Row culture of rootage, to obtain rooted seedling;
(5) rooted seedling is subjected to acclimatization and transplantses.
Quickly bred it is surprisingly found by the inventors that can effectively carry out clove leaf honeysuckle using the method for the present invention, and
And relative to existing clove leaf honeysuckle quick breeding technology, method pollution rate of the invention, the death rate are low, inoculation survival rate,
Inducing clumping bud and rooting rate are high.
In addition, clove leaf honeysuckle according to the above embodiment of the present invention, quickly breeding can also have technology additional as follows
Feature:
According to an embodiment of the invention, the clove leaf honeysuckle sprout is from the annual of wild clove leaf honeysuckle plant
Branch.Thus, clove leaf honeysuckle sprout health easily survives, and grows vigorous, is easy to induce Multiple Buds, is advantageous to numerous enter soon
OK.
According to an embodiment of the invention, the clove leaf honeysuckle sprout is gathered in late August to early September, and prepared
Moisturizing is kept in dark place before explant.Thus, explant easily survives, and is easy to the progress of subsequent step.
According to an embodiment of the invention, before explant is prepared, further comprise entering the clove leaf honeysuckle sprout
The step of row pretreatment.Thereby, it is possible to effectively reduce pollution rate, subsequent inoculations survival rate is improved.
According to an embodiment of the invention, the pretreatment is followed the steps below:By the clove leaf since terminal bud
Running water rinses 6 minutes honeysuckle sprout from top to bottom;Clip under sprout is dipped in into 75% medicinal alcohol 30 seconds, sealed with fritter preservative film
The lower clip of bag;Then whole sprout is put into the solution containing 0.2% dish detergent and soaked 20 minutes;Aseptic water washing 2 times.By
This, subsequent contamination rate is low, and inoculation survival rate is high.
According to an embodiment of the invention, in step (1), when preparing explant:
3 sharp single-edge blades are taken, are soaked 5 minutes in 75% medicinal alcohol;Blade is taken out in calcination on alcolhol burner
10 seconds, the knife back, which is put into small neck, to cool;1 blade is kept to soak, 1 blade is cooling, and 1 blade is in hand outside cutting
Implant, after often doing 5-6 action using blade, more allowing blade replacement.Thereby, it is possible to effectively avoid cross pollution, pollution rate is reduced, is carried
High subsequent inoculations survival rate.
According to an embodiment of the invention, the blade stripping perula for being down to room temperature is taken, in order to avoid sprout of burning.
According to an embodiment of the invention, in step (2), each triangular flask at most 5 explants of sterilization.Thereby, it is possible to
Pollution rate is effectively reduced, improves subsequent inoculations survival rate.
According to an embodiment of the invention, in step (2), when pouring out hydrogenperoxide steam generator, slowly to topple on one side, on one side
Sterilization triangular flask is rotated simultaneously, thimerosal is flowed through each position of bottleneck.Thereby, it is possible to effectively reduce pollution rate.
According to an embodiment of the invention, in step (2), rinsed 3-5 times with aseptic water washing explant.Thereby, it is possible to
Effectively avoid injuring explant because thimerosal remains.
According to an embodiment of the invention, in step (3), each blake bottle is inoculated with an explant.Thereby, it is possible to effective
Pollution rate is reduced, improves inoculation survival rate.
According to an embodiment of the invention, in step (3), the startup proliferated culture medium is added with 2.5mg/L 6-BA
(6- benzyls aminoadenine) and 0.1mg/L NAA (methyl α-naphthyl acetate) WPM culture mediums (Woody Plant medium).Thus, energy
Enough effectively induction explants bear Multiple Buds.
According to an embodiment of the invention, in step (4), the root media for the addition of 0.1mg/L NAA and
0.3mg/L IBA 1/2MS culture mediums.Thereby, it is possible to effectively induce Multiple Buds to take root, the rooted seedling of stalwartness is obtained.
The additional aspect and advantage of the present invention will be set forth in part in the description, and will partly become from the following description
Obtain substantially, or recognized by the practice of the present invention.
