Description
Technical field
The invention belongs to rice paddy seed field, more particularly to a kind of composite water rice life extender and its preparation side
Method and application.
Background technology
Seed longeivity refers to that seed can keep the average life of its viability under certain holding conditions, i.e., seed from
The time that full maturity is undergone untill loss of life power.In actual production, seed longeivity is a community concept, refers to one
Criticize half current in the period, also referred to as seed undergone when seed is reduced to 50% from harvest to germination percentage.Rice under usual conditions
During storage seed occur deterioration, germination percentage decline, particularly hybrid rice seed store 1 year after germination percentage can drop to 70% with
Under, it is impossible to meet production needs and scrap, bring about great losses.For national strategy prepare against natural disasters seed preservation and germ plasm resource
Long-term storage, to seed longeivity extend technical requirements it is even more urgent.
The factors such as environmental condition and holding conditions of the seed longeivity during by heredity, seed development together decide on, that is, are planted
The influence of protonatomic mass, storage temperature and seed moisture content.Research shows, seed lost of life in storage, is mainly
Because seed nucleic acid, film and protein synthesis system suffer damage, peroxidation of membrane lipids, chromosome and gene distortion and
The comprehensive functions such as the degraded of embryo protein；In other storage, the oxidation of the unrighted acid in seed can cause cell membrane
Permeability increase, simultaneous oxidation formed free radical and peroxide protein, the structure of film, cell tissue etc. can be caused
Destroy；MDA is the final product of unsaturated fat acid oxidase in seed, can cause the major injury of seed membranous system, with
The increase of mda content, seed cell membrane structure keeps more complete property to reduce, the aggravation of lost of life degree.Exist in seed
Protection, removing toxic substances, repair system be the important mechanisms for maintaining the life-span.The seeds such as flavone compound protect system, can pass through
Scavenger of ROS limitation membrane lipid peroxidatio plays protective effect.The storage of seeds and detoxication mechanisms and control enzymatic oxidation/antioxygen
It is closely related to change balance.When detoxication mechanisms are affected, seed death is inevitably led to.Numerous studies simultaneously
Show, due to spraying and the characteristics of kind itself for gibberellin, hybrid rice seeds are in seed maturity later stage and storage period
Active physiological metabolism is still remain, so as to cause the consumption of part nutriment, adds the accumulation of harmful substance, harvest
After the storage of a period of time, seed longeivity declines quickly seed, is handled using appropriate inhibiting substances, can reduce and slow down this
The active physiological metabolism of kind, reduces the negative effect thus brought, is advantageous to the extension of seed longeivity.Recent research is found not
Acute variation can occur in storage to albumen synthesis and the related protein of metabolism for storage tolerance seed, and the yeast long-life
Research and nematode life search in show suppress protein translation can effectively lift the life-span.
The speed that the vigor of storage seed declines depends mainly on genetic mechanism, and the environment in seed production process is then
Affect genic expression, i.e., the change in rice paddy seed life-span also with seed moisture content in storage, temperature, humidity, logical
The factors such as gas are relevant, and these influences can be carried out appropriate adjustment by artificial measure and be avoided or mitigate.Light, O2, CO2, micro- life
The chemical substances such as thing, storage pest and the bactericide in order to kill off the insect pests with Institute of Micro-biology, can all have an impact to seed longeivity.
Mainly solve the problems, such as the storage of seeds process lost of life by engineering technology approach both at home and abroad for a long time, including build low
Temperature dries the methods of warehouse, on the basis of substantial amounts of human and material resources and financial resources are consumed, still have a large amount of seed longeivities decline and
Scrap, influence the safe storage and seed quality of seed.Vitality (i.e. life-span) skill is kept in being stored on hybrid rice seeds
The discussion of art, also packing material, pack, storage practice and suffocating treatment Pesticidal technology etc. are grinding for current kind subdomains
Study carefully focus.But so far, still it is applied without a set of effective practical technique in production, even if under refrigerated conditions,
Percentage of seedgermination will also decline year by year, successively decrease more than 3% every year, and lose the effect of seed, thus resource long-term preserve with
And there is also the problem of seed longeivity forfeiture on the deposit of national seed of preparing against natural disasters.Therefore seed longeivity is extended by different approaches,
Not only be biologically one highly inquire into the problem of, and there is great reality in agricultural production and national strategy
Meaning.

In the synthesis of liver.Coumarins medicine is similar to vitamin K structure.Coumarins medicine is in liver and vitamin K epoxies
Compound reductase combines, and suppresses vitamin K and is converted from epoxides to hydroquinone type, the circulation of vitamin K is suppressed.It is it may be said that fragrant
Legumin class medicine is vitamin K antagon, or competitive inhibitor.Used in this formula and mainly suppress water using its
The synthesis of alpha-amylase in rice later stage Rice During Ripening Process, soluble sugar content in rice is reduced, reduce respiration, extend kind
The sub- life-span.
Paclobutrazol：It is the triazole type plant growth regulator succeeded in developing the eighties, is the suppression of endogenous gibberellins synthesis
Agent.The agriculture application value of paclobutrazol is its control effect to plant growth.With plant growth is delayed, suppress cane and stretch
It is long, shorten internode, promote plant tillering, promote bud differentiation, increase plant stress-resistance performance, improve yield and other effects.Originally matching somebody with somebody
Using mainly plant growth is delayed using it in side, effect of the gibberellin (GA) for sprouting is hindered, so as to extend the seed longevity
Life.
The wettable powder of agricultural streptomycin 72%：It is soluble in water, it is antibiotic medicament.Mainly profit is used in this formula
Suppress protein synthesis and broad-spectrum high efficacy antibacterial action with it, kill microorganism inside and outside hybrid rice seeds, mitigate by micro- life
Thing various infringements to caused by seed, so as to extend seed longeivity.
The present invention compared with the prior art, has the following advantages and beneficial effect：
(1) inventive formulation is reasonable, fully utilizes in chemical raw material and natural plants extract to extending seed longeivity
Respective effect, experiments verify that to extend rice paddy seed life-span effect clearly；
