Abstract
The invention discloses a method for inducing calluses of peony anther. A murashige and skoog (MS) culture medium is adopted to induce the calluses; and substances such as 6-benzylamino adenine (BA) cytokinin, a naphthylacetic acid (NAA) plant growth regulator, a 2,4-D herbicide and the like are prepared in the MS culture medium. The definite culture medium scheme and hormone combination are provided for a peony anther explant. The optimal material taking period of the calluses is presented. The inductivity of peony calluses is over 80 percent, and the better induction effect is achieved; and the inductivity of the calluses of the anther is over 50 percent.
Description
The application divides an application for following application:
Application number: 200910083744.3; Denomination of invention: tree peony callus induction method; The applying date: 2009.5.11.
Technical field
The present invention relates to a kind of callus culture method, relate in particular to a kind of tree peony flower pesticide callus induction method.
Background technology
Tree peony is one of China's ten big famous flowers, also is the national flower of China, and the good reputation of " king in spending " is arranged.The tree peony tissue culture mainly is to utilize bud to induce plant and utilize explant to induce by the callus approach, and the callus induction of tree peony is an important stage for regeneration plant, higher callus induction rate lays a good foundation for the later stage differentiation of calli, and how obtaining the kind of higher callus induction rate and type of culture medium, hormone and concentration and condition of culture has confidential relation.
Callus culture is a kind of modal cultivation form, and except that shoot apical meristem cultivation and a part of organ culture, other several plant tissue culture forms finally all will experience callus could produce plant.Callus also usually is the source of suspension cultured cells and protoplast in addition.Callus is divided into embryo callus and non-embryonic callus tissue, and embryo callus is meant the callus of somatic embryo, through being divided into the tender plant of children.
In the prior art, the tree peony Study on tissue culture has had long history, research contents also mainly concentrates on fields such as explant selection, growth regulatory substance proportioning and culture medium prescription, mainly be to utilize stem apex direct development to become plant, and utilize the explant induction callus, utilize the research of callus differentiation generation plant less relatively then, and inducing of callus is the precondition that the callus differentiation produces plant.
There is following shortcoming at least in above-mentioned prior art:
There are callus induction difficulty, rooting rate and problems such as difficulty, brownization, vitrifying are transplanted in of low quality, the domestication of taking root.
Summary of the invention
The purpose of this invention is to provide the high tree peony flower pesticide callus induction method of a kind of callus induction rate.
The objective of the invention is to be achieved through the following technical solutions:
Tree peony flower pesticide callus induction method of the present invention comprises and chooses the tree peony explant, adopts the MS medium to carry out inducing of callus, and described tree peony explant is a flower pesticide, draws materials period: the monokaryon at flower pesticide is drawn materials mid-term;
Described MS medium comprises: MS+2,4-D2.0mg/L+6-BA1.5mg/L+NAA1.0mg/L comprises that also concentration is 6% sucrose.
As seen from the above technical solution provided by the invention, tree peony flower pesticide callus induction method of the present invention, owing to adopt the MS medium to carry out inducing of tree peony anther callus, be furnished with the 6-BA basic element of cell division, NAA plant growth regulator, 2 in the MS medium, materials such as 4-D weed killer herbicide.And the phase is drawn materials the callus induction rate height in due course.
Embodiment
Tree peony flower pesticide callus induction method of the present invention, its preferable embodiment are to comprise and choose the tree peony explant that employing MS medium carries out inducing of callus, is furnished with following one or more materials in the described MS medium:
The 6-BA basic element of cell division, NAA plant growth regulator, 2, the 4-D weed killer herbicide.
Before carrying out the inducing of callus, can cultivate pre-treatment earlier:
At first, selected tree peony explant is carried out 4 ℃ of low temperature treatment;
Then, utilize 2%NaCl0 sterilization 30min, 70% alcohol disinfecting 30s, aseptic water washing 3-5 time.
Specific embodiment:
With different explants is example, adopts different medium and different condition of culture to reach the best effect of inducing.Be that object is set forth respectively below with the different explants:
Inducing of embryo callus:
Cultivation period: annual September, after seed forms;
Cultivate pre-treatment: utilize the method that low temperature (4 ℃) is handled and gibberellin treatment combines, inoculate after utilizing conventional sterilization method (2%NaCl0 sterilize 30min, 70% alcohol disinfecting 30s, aseptic water washing 3-5 time) to sterilize;
Best medium: MS+NAA0.1mg/L+6-BA1.0mg/L;
Callus induction rate reaches 100%.
