Abstract
The present invention relates to a method for generating the somatic embryos of northern schisandra and regenerating plants, particularly to a method for generating cell embryos and regenerating plants. The present invention solves the problems of the existing asexual propagation method of the northern schisandra, for example, the culturing and the breeding period is long, the survival rate is low, and the genic properties of the regenerated plants can not keep accordant with that of female parent. The present invention comprises the following methods: (1) good individual nutritive organs of the northern schisandra are fetched and pre-treated; (2) the nutritive organs are cultured; (3) somatic embryos are subcultured; (4) embryonic calluses are cultured to obtain germinated somatic embryos; (5) the germinated somatic embryos are cultured to obtain complete regenerated plants; (6) the regenerated plants are transplanted in soil to culture, and then seedlings of the northern schisandra are obtained. The present invention has the advantages that the fetching material range of the somatic embryogenesis is board, the breeding speed is high, the proliferation multiple is high, the survival rate reaches above 80 percent, and the present invention can produce the regenerated plants having the same good properties as the female parent in scale.
Description
Technical field
The present invention relates to a kind of blast takes place and plant regeneration method.
Technical background
Fructus schisandrae (Schisandra Chinensis Baill) belongs to the perennial wild woody climber of Schisandraceae (Schisandraceae), and its fruit is important traditional Chinese medicine, also can be used for making wine and making fruit drink.Find the drug ingedient couplet benzene ring octadiene system lignans in recent years in fructus schisandrae fruit, seed and stem, so fructus schisandrae comes into one's own day by day, development prospect is very wide.Because environmental destruction and long-term predation formula are plucked, wild resource destroys serious, and supply falls short of demand in fructus schisandrae market.China fructus schisandrae clone kind " red pearl " has good proterties, but because of it adopts the breeding of growing directly from seeds, does not have ripe vegetative propagation system, is difficult to obtain promote.There are many defectives in the asexual process that adopts at present, as: the cottage propagation method is transplanted a cutting and must just can be taken root with the branch of life in 2 years, and branch quantity is few, and cultivation period is long; Ground stem breeding method root system too a little less than, leave parent after survival rate low, can not be applied to produce; Induce axillalry bud sproutung method propagation multiple low, have only 3.2 times, the long speed of blastogenesis is slow, so also be not suitable for being applied to producing; Zygotic embryo inductor blast take place and the method for plant regeneration method loaded down with trivial details, and be the somatic embryo inducement material with the zygotic embryo, it is consistent with female parent that the genetic character of regeneration plant can not keep.
Summary of the invention
The objective of the invention is the problem that present fructus schisandrae asexual process cultivation period is long, survival rate is low in order to solve, the propagation multiple is low, the long speed of blastogenesis genetic character slow, regeneration plant can not keep and female parent is consistent, and a kind of fructus schisandrae somatic embryo that provides takes place and plant regeneration method.The fructus schisandrae somatic embryo takes place and plant regeneration method carries out according to the following steps: (one) cuts good fructus schisandrae individual nutrition organ and carries out preliminary treatment, be inoculated into then on the MS medium of the 2,4 dichlorophenoxyacetic acid, 10~60g/L sucrose and the 5.0~8.0g/L agar that add 0.5~10mg/L; (2) be 29 ± 1 ℃ in temperature, the photoperiod is to cultivate for 7~9 weeks in the culturing room of the dark 8h of bright 16h/, obtains somatic embryo; (3) somatic embryo is transferred to the identical solid culture medium of (one) step composition in successive transfer culture 2~3 months, obtain callus; (4) the translucent milky embryo callus that successive transfer culture is obtained changes over to and is added with 2 of 0.5~10mg/L, cultivated 25~35 days on the MS medium of 4-dichlorphenoxyacetic acid, transfer to inorganic salt concentration afterwards again and be MS 1/4~1/2 and added on the MS medium of 10~60g/L sucrose and 5.0~8.0g/L agar, be to cultivate for 4~5 weeks, the somatic embryo that obtains germinateing under the condition of the dark 8h of bright 16h/ at 25 ± 1 ℃, photoperiod; (5) somatic embryo that germinates is transferred to (four) and gone on foot in the identical medium of composition and cultivated for 4~5 weeks, obtain complete regeneration plant; (6) regeneration plant is transplanted into the soil cultivation, promptly obtains the fructus schisandrae nursery stock; Wherein preliminary treatment is that nutrition organs is put into concentration with the running water flushing after one day be that 70% alcohol soaks 30s in the step (), use distilled water flushing again 2 times, the liquor natrii hypochloritis who the puts into concentration 3% then 10min that sterilizes is afterwards with sterile distilled water flushing 4~6 times.The fructus schisandrae somatic embryo takes place and plant regeneration method also can carry out according to the following steps: (one) cuts good fructus schisandrae individual nutrition organ and carries out preliminary treatment, be inoculated into then on the MS medium of the 2,4 dichlorophenoxyacetic acid, 10~60g/L sucrose and the 5.0~8.0g/L agar that add 0.5~10mg/L; (2) be 29 ± 1 ℃ in temperature, the photoperiod is to cultivate for 7~9 weeks in the culturing room of the dark 8h of bright 16h/, obtains somatic embryo; (3) somatic embryo is transferred to the identical solid culture medium of (one) step composition in successive transfer culture 2~3 months, obtain callus; (4) the translucent milky embryo callus that successive transfer culture is obtained changes over to and adds 2 of 0.5~10mg/L, cultivated 4~5 months on the MS medium of 4-dichlorphenoxyacetic acid, choose afterwards little group that eugonic embryo callus is cut into 25~35mg transfer to inorganic salt concentration be MS 1/4~1/2 and added on the MS medium of 10~60g/L sucrose and 5.0~8.0g/L agar, be to cultivate for 4~5 weeks, the somatic embryo that obtains germinateing under the condition of the dark 8h of bright 16h/ at 25 ± 1 ℃, photoperiod; (5) somatic embryo that germinates is transferred to (four) and gone on foot in the identical medium of composition and cultivated for 4~5 weeks, obtain complete regeneration plant; (6) regeneration plant is transplanted into the soil cultivation, promptly obtains the fructus schisandrae nursery stock; Wherein preliminary treatment is that nutrition organs is put into concentration with the running water flushing after one day be that 70% alcohol soaks 30s in the step (), use distilled water flushing again 2 times, the liquor natrii hypochloritis who the puts into concentration 3% then 10min that sterilizes is afterwards with sterile distilled water flushing 4~6 times.
The successive transfer culture cycle of fructus schisandrae somatic embryo was 4 weeks.The present invention can induce the bipolar structure with young root, young shoot, than two kinds of different hormones of needs respectively the organ occurring mode of evoking adventive bud, adventive root be more conducive to realize the automated production of nursery stock.Somatic embryo generation scope of selecting material of the present invention is wide, and little to female parent destruction, reproduction speed is fast, propagation multiple height, the 30mg embryo callus can obtain 1800~2200 individual cells embryos in 2 months, bud fast growth, cultivation growth in 15 days 2.0~3.0cm, and survival rate is up to more than 80%.But the present invention's hybrid vigor fixing, a large amount of production and maternal regeneration plant with identical merit used for many years and be need not the breeding process of complexity such as three series mating.And the present invention also can be used as the modular system of different biological events in the research plant embryos generating process.
