Description
Technical field
The invention belongs to the super dried preservation technical field of seed, relate in particular to a kind of method of super dried preservation khuskhus seed.
Background technology
Khuskhus is the good tropical leguminous forage of a class, originates in Central and South America.This genus has kind or 44 of subspecies, accounts for 1/3rd of the torrid zone, the world, south subtropics area sown pasture herbage variety, in the torrid zone, China south China, the establishing in large scale utilization of south subtropics area.It has the characteristics of drought-enduring, acidproof infertile soil, high yield, high-quality, the suitable torrid zone and the plantation of south subtropics area.Be mainly used in herding, green fodder, processing hay meal, green manure, orchard, rubber plantation cover crop and water and soil conservation etc.This herbage all has plantation in Australia, South America, Southeast Asia and African country as tropical pasture, and it also is China torrid zone, the most important tropical pasture in south subtropics area, has broad application prospects.Khuskhus is the part of tropical pasture germ plasm resource mainly with seminal propagation, and its seed is the indispensable material base of the good tropical pasture kind of seed selection, is the important materials of carrying out physiologic theory research.Prolong the seed storage life-span to greatest extent, significant for the long preservation of germ plasm resource and high price seed.But, also do not set up the khuskhus seed bank at present in the torrid areas, and khuskhus is preserved with live body mainly, will more plant once again in per 2～3 years, preserves the khuskhus germplasm by this way and has some disadvantages.Carry out the super dried preservation research of tropical pasture seed, protection, breeding and the germ plasm resource of its bio-diversity are preserved with utilization have very important scientific meaning and application prospect.
Seed moisture content and reserve temperature are two most important factors that influence the seed storage life-span, suitably reduce seed moisture content and reserve temperature and all can effectively prolong seed longevity.But be subjected to the restriction of dry technology and dewatering for a long time, generally believe that stored seeds should not be too dried, classical theory is decided to be seed safety water content lower limit with 5%～7% water content, thinks and breaks through the generation that this lower limit will speed up seed vitality decline and blastation.The condition of the long preservation seed germplasm that FAO (Food and Agriculture Organization of the United Nation) (FAO) and IBPGR (IBPGR) formulate is that the water content of 5%-7% and-18 ℃～-25 ℃ reserve temperature are the general accepted standard in various countries, the world today (IBPGR, 1976).But, the low temperature storage plant germplasm is costly, this is to be difficult to realize for economically less developed region and single breeding units, seed operating unit, and the seed storage technology that develop energy-conservation, economical and convenient and safety is the great practical problem that the preservation plant germplasm resource need solve.
The super dry-storage of seed is the research focus of phase late 1980s germplasm preservation aspect rise, being intended to explore seed moisture content, to be reduced to traditional lower limit following but still effectively keep the dry technology of seed vitality, to reach the purpose of long preservation germ plasm resource under normal temperature condition.Because this technology can reduce the expense of building the storehouse and keeping the storehouse running significantly, have huge economic benefit and application prospect in the germ plasm resource preservation.It preserves technology as energy-saving and environmental protection, economical and practical seed, is subjected to the favor of countries in the world.
Super dry-storage energy significant prolongation seed longevity, storage effect is not second to low temperature storage.1986, the Ellis of Britain was reduced to 2% with the sesame seed moisture content from 5%, and discovery can make its shelf-life prolong more than 40 times, and this is equivalent to reserve temperature from 20 ℃ of effects (Ellis and Hong, 1986) that are reduced to-20 ℃.The imagination of super dry storage has been proposed on this basis.In recent years, both at home and abroad super the dried preservation research of seed has been obtained remarkable progress, not only in the physiology of seed field, and has all started no small upsurge in germ plasm resource preservation field, part Study result delivers (Zheng et al., 1998 at " Nature "; Ellis and Roberts, 1998; Demir and Ozcoban, 2007; Perez-Garcia et al., 2007).Compare with low temperature or ultralow temperature storage practice, although the problem that super dry storage exists some to solve technically, this technology is simple and easy to do relatively, small investment, and running expense is low throughout the year, and in environmental protection positive effect is arranged.
There are larger difference in the super dry-storage effect of different monoid seeds, anti-dried degree and super dried time wet condition, and at present, the seed of super dry-storage relates to about more than 50 species, mostly is the seed of vegetables, melon and fruit, beans, cereal, medicinal plant and trees greatly.Studies have shown that most seeds can be down to water content below 5%～7% safely by special dry technologies such as freezing vacuum drying, air blast silica dehydrator, desiccant room temperature dryings, seed storability at normal temperatures increases substantially, in conjunction with specific packing technique, can obtain better preservation effect (Wang Xiaofeng etc., 2001).
People such as Ellis are doing number of research projects aspect the super dry storage of seed, successively the seed of more than 20 kind of kinds such as paddy rice, barley, wheat is tested, the result shows, in certain water content ranges, all all meet seed moisture content and the storage temperature action rule to the seed storage life-span for planting experimentally son, but not of the same race suitable water content lower limit difference (Ellis, 1998; Leon-Lobos and Ellis, 2002; Ellis and Hong, 2006).
The research of the relevant super dry storage of China is started late with respect to Britain.Zheng Guanghua etc. at first carried out the super kept dry research of seed in China in 1989, and were obtaining certain progress (Zheng et al., 1998) aspect the physiology of super dry seed and the cytology.Zheng Guanghua, Cheng Hongyan, Wang Xiaofeng etc. to Chinese cabbage seeds research think, Chinese cabbage seeds through super dried technical finesse, its water content was down to 1.6% o'clock, its seed germination rate and vigor are without any obvious variation, and aspect vitality index and the germination rate burin-in process there is being more patience (Wang et al., 2003) than the contrast seed.People such as Sun Hongmei place 50,35,20 ℃ of storages respectively with the corn seed of different moisture content, and the result shows the optimum moisture content difference of corn seed storage under the different temperatures, presents with the reduction of reserve temperature trend of rising (Sun Hongmei etc., 2004).People's such as Zhou Xiangsheng research thinks that seeds such as the rape of high oil content, radish, Semen sesami nigrum are suitable for super kept dry, but suitable water content lower limit not of the same race variant (Zhou Xiangsheng and Bi Xinhua, 1993).In order to solve the imbibition damage problem after super dry handle of seed, people such as Zhang Yun orchid carried out different times wet methods to the super dry seeds of crops such as pea, millet in 1994 and have compared, think same variety seeds sometimes its high-moisture seed and low moisture seed adapt to return wet method different, should adopt the suitable wet method of returning according to its seed moisture content height is different.Poly-diethanol (PEG) is returned wet seed, and its concentration transfers influential effect very big to oozing, if improper use does not only have the repairing effect that the accent effect impairs cell membrane on the contrary of oozing.
Seed moisture content and reserve temperature are two most important factors that influence the seed storage life-span, suitably reduce seed moisture content and reserve temperature and can effectively prolong seed longevity, and the method for preserving seed at present mainly contains three kinds:
(1) low temperature or ultralow temperature storage practice, being about to the seed germplasm preserves under the condition of the reserve temperature of the water content of 5%-7% and-18 ℃～-25 ℃, the low temperature storage plant germplasm is costly, is difficult to realize for economically less developed region and single breeding units, seed operating unit.
(2) live body is preserved the khuskhus germplasm, will more plant once again in per 2～3 years, and it is time-consuming to take ground.
(3) super dry storage is energy-conservation, easy, an effective seed storage technology.Although the problem that exists some to solve technically, this technology is simple and easy to do relatively, small investment, and running expense is low throughout the year, and in environmental protection positive effect is arranged.
At present, the seed of super dry-storage relates to about more than 50 species, mostly is the seed of vegetables, melon and fruit, beans, cereal, medicinal plant and trees greatly.Studies have shown that most seeds can be down to water content below 5%～7% safely by special dry technologies such as freezing vacuum drying, air blast silica dehydrator, desiccant room temperature dryings, seed storability at normal temperatures increases substantially, in conjunction with specific packing technique, can obtain better preservation effect.But there are larger difference in the super dry-storage effect of different monoid seeds, anti-dried degree and super dried time wet condition.
