Description
The present invention relates to the improvement to microreproduction technology, in more detail, it is a kind of method and apparatus of dividing plant material.
The benefit of plant micropropagation is well-known:
1. it provides a kind of controlling plant disease, thereby improves the both convenient and effective method of plant quality.And the release disease, this point becoming resemble to the Middle East promising export market of this class applied at the sign that becomes more and more important aspect the quarantine request.
2. the micropropagation of plant, it can provide a kind of method of fast breeding.Except conduct reached remarkable this ubiquity meaning of means that increases of quantity, it was returned people and brings some other special benefit.For the production of the commercial numbers of new varieties, can be by manual micropropagation, approximately only the needization expense just can reach with the conventional method required time half.Even be easy to the species of breeding like this by slitting for resembling liane, and can provide convenience for increasing large quantities of new varieties apace, also be very important.
3. micro-propagation technique, it makes and utilizes the space to become possibility more prolifically.The cultivation again of plant helps to obtain for the gratifying high usage of lab space.Also impel people to utilize the space of greenhouse and plant " adaptability exercise " better.On the market of seasonal supply, although number needs to increase, because the quick breeding of kind just needn't leave idle place in the storehouse midium or long term.Under the condition that temperature, periodicity of illumination and nutrient balance are controlled, can continue in any time in 1 year to operate.Cultivate storage, perhaps temperature is reduced, all can be used to slow down the growth rate of plant, provide the high yield that adapts on the time so that adapt to seasonal needs.
Micro-propagation technique is applied to the correlation that species are improved to be needed to discern between vegetable material, medium and the breeding condition three.Having designed the successful species scope that standardized micropropagation job step was suitable for promptly increases along with the continuous growth of the potential field in the commercialization application.Setting foot in the Australian of micropropagation work and the number of other some foreign nursery stock culturists has increased in nearest 6 years greatly.The main path of having adopted has two: at first being that laboratory and existing nursery is integrated, is that this nursery is expanded widely subsequently; Also can only set up the laboratory, and the plant in will cultivating is sold to other nursery.Though begin slowlyer, the demand for the nursery of micropropagation plant and grower is just promptly increasing afterwards.
The operating sequence of carrying out micropropagation by organ culture can be summarized as follows:
1. initial incubation.Take off spray from selected plant, carry out surface sterilization, be put into thereafter in the medium of sterilization.
2. the bud on these sprays can continued growth, so it is cultivated in the proliferated culture medium (SM) at spray again.
3. spray is promptly grown in the spray proliferated culture medium, and a large amount of clone sprays is provided.For the quantity that increases spray and to keep strain constant, to cultivate again in fresh spray propagation base every 3 to 4 all sprays.
4. cultivate at petri diss or similarly during the root media (RM) in the container when the sample of spray, root obtains growing again.
Plant is is normally loaded and transported in laminate container.The plant recipient shifts out plant under the situation of bacterium of not going out from container, and carries out " adaptive training " at external condition in the very high environment of humidity.
Cultivate again normally and to transplant indoor carrying out.Indoor in transplanting, use sterile tweezers that spray is shifted out from container, use sterile scalpel that they are cut apart, all be to be divided into cluster bunch little spray or single spray very roughly usually, be put into then in the fresh medium.The stripping and slicing of the meristematic cell that does not comprise sufficiently complete that is partitioned into will poor growth or is not grown fully.The plant that comprises or do not comprise noble cells completely hardly will can regeneration " typically " or clonal plant.
In this operation process, maximum cost is that spray is cultivated the work of changing expense the another kind of medium again from a kind of medium.The expense of Pei Yanging is at least three times of the required expense of all other operation process again.Its reason can describe with the cultivation again of arbor.For the skilled person, finishing 5,000 culture transferring operations every day, here all is very high index.No matter these operations are in macroscopic view or all are subjected to the restriction of identical productivity ratio in the microcosmic scopes.In addition, in many laboratories, the control of germ-free condition is incomplete, just may be very big to such an extent as to pollute loss.The purification of container for plants, outfit, control and slitting store with adaptability exercise place between transfer and its culture transferring exercised base to adaptability, these operations all are labor intensive power.
Thereby, the ability that at present Australian and external nursery stock cultivation industry is satisfied for the demand of micropropagation plant is subjected to making the cost of slitting process by hand in the micropropagation process, and even by the very big restriction of the most skilled operating personnel at the maximum operation amount every day that does not have just can finish under the situation of adverse effect.
So, the object of the present invention is to provide a kind of method and apparatus of dividing plant material.It will overcome above unfavorable factor, and this unfavorable situation is improved.
