Description
Technical field
The invention belongs to rice paddy seed field, more particularly to a kind of formula and system for improving hybrid rice seeds storage capacity
Preparation Method and application.
Background technology
The storage of seeds ability refers to that seed can keep the average life of its viability under certain holding conditions, that is, plants
The time that son is undergone from full maturity to loss of life power.It is different from the storage of common paddy, kind must be still reached after the storage of seeds
Sub- germination percentage standard, the needs of crop production could be met.But seed vitality and germination percentage decline after general rice storage, hybridization
Germination percentage can drop to less than 70% after rice is stored 1 year, it is impossible to meet production needs and scrap, bring about great losses.It is right
Prepared against natural disasters in national strategy the preservation of seed and the long-term storage of seed resource, to extending the technical requirements of the storage of seeds ability more
It is urgent.
Because seed long keeping ability is determined by factors such as heredity, the environmental condition during seed development and holding conditions jointly
It is fixed, i.e., influenceed by seed quality, storage temperature and seed moisture content.Mainly pass through engineering technology both at home and abroad for a long time
Approach come solve the storage of seeds ability shorten problem, including build low temperature drying warehouse the methods of, consume substantial amounts of manpower,
On the basis of material resources and financial resources, still there are a large amount of seed vitalities to decline and scrap, influence the safe storage and seed quality of seed.
Numerous studies show that seed vigor in storage declines, and is primarily due to seed nucleic acid, film and protein
Synthesis system suffers damage, the comprehensive function such as peroxidation of membrane lipids, the distortion of chromosome and gene and degraded of embryo protein；Separately
In outer storage, the oxidation of the unrighted acid in seed can cause membrane passage to increase, and simultaneous oxidation is formed
Free radical and peroxide protein, the structure of film, cell tissue etc. can be damaged.Seed protection system can pass through
Scavenger of ROS limitation membrane lipid peroxidatio plays protective effect.Recent studies indicate that stored intolerant to stored seedses
Acute variation (Gao2016) can occur for the protein related with metabolism to albumen synthesis in journey.In addition, histon deacetylase (HDAC)
Activator resveratrol can effective anti-aging (Yin offers brightness 2013).Numerous studies also indicate that simultaneously, due to gibberellin
Spray and the characteristics of kind itself, hybrid rice seeds still remain active physiology in seed maturity later stage and storage period
Metabolism, so as to cause the consumption of part nutriment, adds the accumulation of harmful substance, storage of the seed through a period of time of harvest
Behind Tibetan, seed vitality declines quickly, is handled using appropriate inhibiting substances, can reduce and slow down this active physiological metabolism,
The negative effect thus brought is reduced, is advantageous to the raising of seed long keeping ability.In addition, the change of rice paddy seed storage capacity
Also relevant with the factor such as seed moisture content, temperature, humidity, ventilation in storage, these influences can be fitted by artificial measure
When adjustment is avoided or is mitigated.Light, O2、CO2, microorganism, storage pest and for the sterilization to kill off the insect pests with Institute of Micro-biology
The chemical substances such as agent, can all have an impact to the storage of seeds ability.
On hybrid rice seeds storage capacity keep Discussion on Technology, including packing material, pack, storage practice and
Suffocating treatment insect prevention and be the study hotspot of current kind subdomains with Storage in cold bank technology etc..But so far, do not have still
A set of effective practical technique is applied in production, even if under refrigerated conditions, percentage of seedgermination will also decline year by year, often
Year successively decreases more than 3%, and loses the effect of seed, so also being deposited on the deposit that resource long-term preserves and country prepares against natural disasters seed
Seed vitality is lost the problem of.Therefore extend the storage of seeds ability by different approaches, be not only biologically one non-
The problem of constant value must be inquired into, and there is Great significance in agricultural production and national strategy.
The content of the invention
In place of solving shortcoming and defect present in above-mentioned prior art, primary and foremost purpose of the invention is to provide one
Kind improves the formula of hybrid rice seeds storage capacity.The formula can be by being used alone or by ripe with rice paddy seed
The field management measure in later stage combines to improve the storage capacity of rice paddy seed.
Another object of the present invention is to provide the preparation method of above-mentioned formula.
It is still another object of the present invention to provide the application of above-mentioned formula.
