Abstract

The invention discloses a kind of in vitro to promote non-florescence Kiwi berry into colored method, after the accumulation that isolated shoot is carried out to certain chilling requirement, give suitable external environmental condition, it is set to be developed according to set pattern growth, reach the purpose buddingged bloom in advance, compared with prior art with advantages below:A) non-florescence Kiwi berry is caused to obtain bud, Kiwi berry monoploid (dihaploid) germplasm innovation can repeatedly be carried out by realizing 1 year;B) have a wide range of application, extend to other orchard fruits, Initial experiments material is provided for the germplasm innovation based on monoploid (dihaploid) technology.

Description

A kind of in vitro promotes non-florescence Kiwi berry into colored method
Technical field
The present invention relates to agricultural technology field, more particularly to a kind of in vitro to promote non-florescence Kiwi berry into colored side Method.
Background technology
Plant haploid (dihaploid) technology is a kind of rapidly and effectively germplasm innovation method, can be (small by flower pesticide Spore) method of culture realizes, it is used for the industrial crops such as Cruciferae, grass family and tobacco, but such as each in xylophyta Using less in fruit trees.Fruit tree is as a kind of xylophyta, and its brephic (juvenile phase) is longer, and latter year of growing up blooms once; Season plantation more than a year can not be realized as the herbaceous plant such as wheat and rice and into flower.This serious obstruction is (double based on monoploid Monoploid) technology fruit tree germplasm innovation process.
At present, monoploid (dihaploid) technology is not carried out substantially in Actinidia germplasm innovation.Actinidia shows There are 54 kinds and 21 mutation, wherein actinidia eriantha can constantly budding between 1 year, bloom, result, and remaining Kiwi berry kind is such as Chinese gooseberry and the Kiwifruit cultigen high as market application value, and breeding scholar's germplasm innovation are main Object, 1 year florescence only once, even actinidia eriantha also can only obtain bud within its growth period so that based on monoploid The germplasm innovation cycle of (dihaploid) technology is longer, compared with traditional crossbreeding, it is impossible to embody monoploid to greatest extent The superiority of (dihaploid) germplasm innovation.
The Physiological Differentiation of macaque peach bud is completed before surviving the winter.The branch for completing bud Physiological Differentiation has possessed to form bud Genetic prerequisite, i.e. related gene carried out selective expression.Give suitable condition in vitro branch, can make its according to it both Determine development models to sprout in advance, bud can be obtained, so as to solve the bottle that monoploid (dihaploid) technology is applied in fruit tree Neck problem.
The content of the invention
Goal of the invention:In order to overcome problems of the prior art, the present invention proposes one kind so that Kiwi berry shifts to an earlier date Budding and bloom, method is simple to operation, and a kind of strong in vitro of generalization promotes non-florescence Kiwi berry into colored method.
Technical scheme:In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is:A kind of in vitro Non- florescence Kiwi berry is promoted to comprise the following steps into colored method:
(1) branch selection and processing:It is collected the branch for being used as cuttings November;Gathered on the staminiferous plant good from tree vigo(u)r The branch of annual lignifying, it is placed in 0-4 DEG C of refrigerator cold-storage with wet newspaper parcel and handles;
(2) preparation of cutting bed:Cutting bed is built in the warmhouse booth of area without shade, and cutting bed bottom soil deep tillage is exposed to the sun simultaneously Wide 80-100cm furrow are made, the high cutting mediums of 15-20cm are laid thereon, through being exposed to the sun and spraying and spray universal bactericide 25% 1500 times of Fluoxastrobin dilution and the high 1000-1500 times of dilution of 10% generation have the function that sterilizing pesticide;
(3) cuttings prepares:The branch of step (1) chilling treatment is taken out, the cuttings for cutting into 10-15cm is tied up, incision Mouth alignment, and lower cut is immersed in rooting powder solution 10-12h, upper cut coats wound smears, prevents the invasion of pest and disease damage It is lost with moisture;
(4) cuttage:Cuttage depth is the 1/2-2/3 of cutting length;Poured with watering can permeable after cuttage, make cuttings and cutting bed Cutting medium fully contacts;
(5) management after cuttage:Temperature control is at 20-25 DEG C;Cuttings do not sprout the last week pour it is permeable once, take out tip lamina Pour within 2-3 days afterwards it is permeable once;Requirement generally to moisture is seedbed top layer sandy soil non-whitening, holds agglomerating but not water outlet and is Preferably;Fine day needs to shade, and noon temperature Gao Shixu lifts canopy ventilation;
(6) cuttings, which is sprouted, buddings and dredges flower bud, and collection microspore is in monokaryotic stage to the bud of double-core early stage and is used for monoploid (dihaploid) germplasm innovation is tested.
In the step (1) the chilling treatment time be not less than 1 week, on the one hand progress chilling requirement accumulation, on the one hand to from Body branch is preserved.
It is more highly preferred to, the cutting medium in the step (2) is that thin river sand, vermiculite and peat soil press 2:1:2 quality Ratio mixes.
It is that 20% 1000-2000 times of methyl α-naphthyl acetate Dilution for powder configures with containing active ingredient to obtain more excellent rooting efficiency The rooting powder solution immersion cuttings lower cut formed.
It is more highly preferred to, the selection of time of cuttage November to next year crop field Kiwi berry sprout then in the step (4) Before sprouting.
To ensure that nutrition supply is sufficient needed for flower bud development, the bud collection in the step (6) is specially young sprout 2-3cm Pinching, each cuttings retain 2-4 bud.
Further, secondary flower bud is extractd in the collection selection of the bud.
The present invention principle be:After the Physiological Differentiation of macaque peach bud, that is, the selective expression of related gene is completed, in vitro After branch completes certain chilling requirement accumulation, suitable external environmental condition is given, it is developed according to set pattern growth, reaches To the purpose bloomed of buddingging in advance.
Beneficial effect:A kind of in vitro provided by the invention promotes non-florescence Kiwi berry into colored method, will be in vitro After branch carries out the accumulation of certain chilling requirement, suitable external environmental condition is given, it is developed according to set pattern growth, Reach the purpose buddingged bloom in advance.There is advantages below compared with prior art:A) non-florescence Kiwi berry is caused to obtain bud, Kiwi berry monoploid (dihaploid) germplasm innovation can repeatedly be carried out by realizing 1 year;B) have a wide range of application, extend to other wood This fruit tree, Initial experiments material is provided for the germplasm innovation based on monoploid (dihaploid) technology.
