Qhia peb:
S-abscisic acid muaj cov teebmeem physiological xws li ua rau lub paj dormancy, nplooj hlav thiab inhibiting cell loj hlob, thiab tseem hu ua "dormant hormone".
Nws tau tshawb pom nyob ib puag ncig xyoo 1960 thiab tau yuam kev lub npe vim nws muaj feem cuam tshuam nrog kev poob ntawm nplooj nplooj. Txawm li cas los xij, tam sim no paub tias kev poob ntawm cov nplooj thiab txiv hmab txiv ntoo yog tshwm sim los ntawm ethylene.

S-abscisic acid yog ib puag ncig tus phooj ywg ntsuab khoom,S-abscisic acid yog ib qho kev loj hlob ntawm cov nroj tsuag active tshuaj.
Cov khoom ntuj no feem ntau pom muaj nyob hauv cov nroj tsuag. Nws yog ib txwm muaj nyob rau hauv txiv hmab txiv ntoo, zaub thiab nplej noj los ntawm tib neeg thiab muaj kev nyab xeeb rau tib neeg thiab ib puag ncig.

Cov khoom siv raw siv hauv cov txheej txheem ntawm abscisic acid technical yog tag nrho cov khoom tsis muaj tshuaj lom thiab tsis muaj mob ua liaj ua teb thiab cov khoom lag luam sab nraud. Nws tau txais los ntawm microbial fermentation, tsis muaj qhov sib ntxiv ntawm cov khoom tsis zoo lossis cov tshuaj, thiab tsis muaj cov tshuaj lom hauv nws cov qauv tshuaj.

Kev siv ntawm S-abscisic acid

1.S-abscisic acid yog ib qho zoo inhibitor ntawm noob germination
S-abscisic acid tuaj yeem siv rau kev khaws cov noob thiab kev khaws cia.

2. S-abscisic acid tuaj yeem txhawb nqa cov khoom khaws cia hauv cov noob thiab txiv hmab txiv ntoo, tshwj xeeb tshaj yog khaws cia cov protein thiab qab zib.
Kev siv abscisic acid nyob rau theem pib ntawm cov noob thiab kev loj hlob ntawm txiv hmab txiv ntoo tuaj yeem ua tiav lub hom phiaj ntawm kev nce cov qoob loo ntawm cov qoob loo thiab txiv hmab txiv ntoo.

3. S-abscisic acid tuaj yeem txhim kho qhov txias thiab Frost tsis kam ntawm cov nroj tsuag.
S-abscisic acid tuaj yeem siv los pab cov qoob loo tiv taus qhov kub thiab txias tsis zoo thaum lub caij nplooj ntoo hlav thaum ntxov thiab cog qoob loo tshiab uas muaj zog tiv taus txias.

4. S-abscisic acid tuaj yeem txhim kho drought tsis kam thiab ntsev-alkali kam rau ntawm cov nroj tsuag.
S-abscisic acid muaj txiaj ntsig zoo heev hauv kev pab tib neeg tiv thaiv ntau thiab ntau qhov chaw qhuav dej, tsim thiab siv cov teb nruab nrab thiab tsis tshua muaj txiaj ntsig, thiab kev cog qoob loo.

5. S-abscisic acid yog ib qho kev loj hlob inhibitor.
S-abscisic acid tuaj yeem cuam tshuam kev loj hlob ntawm tag nrho cov nroj tsuag lossis cov kab mob sib cais. Cov txiaj ntsig ntawm ABA ntawm cov nroj tsuag loj hlob yog qhov sib txawv ntawm IAA, GA, thiab CTK, thiab nws inhibits cell division thiab elongation. inhibit qhov elongation thiab kev loj hlob ntawm cov kabmob xws li bud sheaths, twigs, cag, thiab hypocotyls.

6. Daim ntawv thov ntawm S-abscisic acid hauv vaj paj
Txij li thaum S-abscisic acid (ABA) tuaj yeem kaw lub qhov hws loj ntawm nplooj, nws tuaj yeem siv los khaws paj, ua kom lub sijhawm paj ntev (lub ntsiab lus ntawm paj preservatives), tswj lub sijhawm paj, thiab txhawb kev cog qoob loo (horticultural regulation).

Yuav siv li cas S-abscisic acid ua ke
1. S-abscisic acid + auxin
Feem ntau txhawb rooting thiab seedling retardation tom qab transplanting seedlings, los yog seedling cuttings, thiab lwm yam.

2. Ethylhexyl + S-abscisic acid, S-abscisic acid + gibberellin
Lub luag haujlwm yog los tswj kev loj hlob ntawm kev loj hlob thiab nce txiv hmab txiv ntoo.

3. Anti-agonist + S-abscisic acid
Ua kom muaj kev nqus ntawm cov as-ham, txhawb kev loj hlob ntawm cov yub, ua kom tag nrho cov khoom qhuav, thiab txhim kho qhov txias txias, drought-resistant, kab mob, thiab kab-resistant.
