S-Abscisic Acid (ABA) Muaj nuj nqi thiab siv cov nyhuv
1.S-Abscisic Acid (ABA) yog dab tsi?
S-Abscisic Acid (ABA) yog cov tshuaj cog qoob loo. S-Abscisic Acid yog lub ntuj cog kev loj hlob regulator uas tuaj yeem txhawb kev sib koom ua ke cog kev loj hlob, txhim kho cov nroj tsuag kev loj hlob zoo, thiab txhawb nqa cov nplooj ntoo. Hauv kev ua liaj ua teb, Abscisic Acid feem ntau yog siv los ua kom cov nroj tsuag tus kheej tsis kam lossis kev hloov kho rau kev nyuaj siab, xws li kev txhim kho cov nroj tsuag drought-resistant, txias-resistant, kab mob-resistant, thiab ntsev-alkali tsis kam.
2.Mechanism ntawm kev ua ntawm S-Abscisic Acid
S-Abscisic Acid yog dav nyob rau hauv cov nroj tsuag, thiab ua ke nrog gibberellins, auxins, cytokinins, thiab ethylene, nws yog lub tsib loj cog endogenous cov tshuaj hormones. Nws tuaj yeem siv dav hauv cov qoob loo xws li nplej, zaub, paj, nyom, paj rwb, tshuaj ntsuab hauv Suav teb, thiab cov ntoo txiv hmab txiv ntoo los txhim kho txoj kev loj hlob thiab fruiting npaum li cas thiab zoo ntawm cov qoob loo nyob rau hauv kev loj hlob tsis zoo ib puag ncig xws li tsis tshua muaj kub, drought, caij nplooj ntoos hlav. txias, salinization, kab tsuag thiab kab mob, ua rau kom cov qoob loo ib cheeb tsam ntawm nruab nrab thiab qis-yield teb, thiab txo cov kev siv tshuaj tua kab.
3. Kev siv cov nyhuv ntawm S-Abscisic Acid hauv kev ua liaj ua teb
(1) S-Abscisic Acid txhim khu kev tiv thaiv rau abiotic stress
Hauv kev ua liaj ua teb, cov qoob loo feem ntau raug kev nyuaj siab (xws li drought, tsis kub, salinity, tshuaj tua kab, thiab lwm yam).
Nyob rau hauv qhov kev nyuaj siab ntxhov plawv tam sim ntawd, daim ntawv thov ntawm S-Abscisic Acid tuaj yeem qhib cov xovtooj ntawm tes ntawm cov plasma daim nyias nyias ntawm cov nplooj hlwb, ua rau kom tsis sib xws ntawm nplooj stomata, txo cov dej hauv cov nroj tsuag hauv lub cev, thiab txhim kho cov nroj tsuag cov dej tuav thiab tolerance rau drought.
Nyob rau hauv qhov kub tsis tshua muaj kev ntxhov siab, daim ntawv thov ntawm S-Abscisic Acid tuaj yeem ua rau cov kab mob khaub thuas tiv thaiv kab mob thiab ua rau cov nroj tsuag tsim cov kab mob khaub thuas.
Nyob rau hauv av ntsev vau kev nyuaj siab, S-Abscisic Acid tuaj yeem ua rau muaj kev sib txuam loj ntawm proline, ib qho osmotic regulating tshuaj nyob rau hauv cov nroj tsuag, tswj kev ruaj ntseg ntawm cell membrane qauv, thiab ua rau kom muaj kev tiv thaiv enzymes. Txo cov Na + cov ntsiab lus rau ib chav tsev qhuav qhov hnyav, ua kom cov carboxylase ua haujlwm, thiab txhim kho cov ntsev kam rau ntawm cov nroj tsuag.
Raws li kev ntxhov siab ntawm cov tshuaj tua kab thiab cov chiv puas tsuaj, S-Abscisic Acid tuaj yeem tswj hwm qhov sib npaug ntawm cov tshuaj hormones endogenous hauv cov nroj tsuag, nres kev nqus ntxiv, thiab tshem tawm cov kev tsis zoo ntawm cov tshuaj tua kab thiab chiv puas. Nws tseem tuaj yeem txhim kho kev koom tes thiab sib sau ntawm anthocyanins thiab txhawb cov qoob loo xim thiab kev loj hlob ntxov.
2) S-Abscisic Acid txhim khu kev tiv thaiv ntawm cov qoob loo rau cov kab mob
Qhov tshwm sim ntawm kab tsuag thiab kab mob yog inevitable thaum lub sij hawm loj hlob ntawm cov nroj tsuag. Nyob rau hauv cov kev ntxhov siab ntawm cov kab mob, S-Abscisic Acid induces lub activation ntawm PIN noob nyob rau hauv cov nroj tsuag nplooj hlwb los tsim cov protein enzyme inhibitors (flavonoids, quinones, thiab lwm yam), uas cuam tshuam qhov kev cuam tshuam ntxiv ntawm cov kab mob, zam kev puas tsuaj lossis txo qhov kev puas tsuaj. rau cov nroj tsuag.
(3) S-Abscisic Acid txhawb kev hloov xim thiab sweetening ntawm txiv hmab txiv ntoo
S-Abscisic Acid muaj cov nyhuv ntawm kev hloov xim thaum ntxov thiab qab zib ntawm cov txiv hmab txiv ntoo xws li txiv hmab txiv ntoo, citrus, thiab txiv apples.
(4) S-Abscisic Acid tuaj yeem nce tus naj npawb ntawm cov hauv paus hniav thiab cov hauv paus hniav ntawm cov qoob loo.
Rau cov qoob loo xws li paj rwb, S-Abscisic Acid thiab chiv xws li humic acid yog dripped rau hauv dej, thiab cov yub tawm nrog cov dej ntws. Nws tuaj yeem nce tus naj npawb ntawm cov hauv paus hniav thiab adventitious keeb kwm ntawm paj rwb seedlings mus rau ib qho twg, tab sis nws tsis pom tseeb nyob rau hauv paj rwb teb nrog siab alkalinity.
(5) S-Abscisic Acid yog tov nrog chiv kom sib npaug cov as-ham thiab ua lub luag haujlwm hauv kev poob phaus.
4.Kev ua haujlwm ntawm S-Abscisic Acid
Cog "Growth balance factor"
Txhawb kev loj hlob hauv paus thiab ntxiv dag zog rau cov hauv paus hniav, txhawb kev loj hlob ntawm cov hauv paus hniav capillary; txhawb kev loj hlob ntawm cov tub ntxhais hluas muaj zog thiab nce tawm los; txhawb sprouting thiab paj preservation, nce txiv hmab txiv ntoo tus nqi; txhawb cov txiv hmab txiv ntoo xim, sau thaum ntxov, thiab txhim kho zoo; txhim khu kev nqus cov as-ham thiab txhim kho kev siv cov chiv; compound thiab nce efficiency, thiab txo cov tshuaj tsis zoo xws li txiv hmab txiv ntoo deformity, hollows, thiab cracked txiv hmab txiv ntoo.
Nroj tsuag "tiv taus induction factor"
Induce qoob loo tiv thaiv kab mob thiab txhim kho kab mob tiv thaiv; txhim kho cov qoob loo tiv thaiv kev nyuaj siab (txias tiv taus, drought resistance, waterlogging resistance, ntsev thiab alkali tsis kam, thiab lwm yam); alleviate thiab txo cov qoob loo puas tsuaj.
Green thiab environmentally friendly khoom
S-Abscisic Acid yog cov khoom ntuj ntshiab uas muaj nyob rau hauv tag nrho cov nroj tsuag ntsuab, feem ntau tau los ntawm microbial fermentation, tsis muaj tshuaj lom thiab tsis ua rau tib neeg thiab tsiaj txhu. Nws yog ib hom tshiab ntawm kev ua tau zoo, ntuj ntsuab cog kev loj hlob active tshuaj nrog dav daim ntawv thov prospects.
5. Daim ntawv thov S-Abscisic Acid
Nws yog tsuas yog siv rau hauv nplej, nplej, lwm yam zaub mov loj, txiv hmab txiv ntoo, txiv lws suav, citrus, haus luam yeeb, txiv laum huab xeeb, paj rwb thiab lwm yam zaub, txiv hmab txiv ntoo thiab roj qoob loo. Nws plays lub luag haujlwm tseem ceeb hauv kev tswj kev loj hlob, txhawb kev cog qoob loo thiab txhawb cov xim.
