Brassinolide: 14-Hydroxylated Prassinolide (Crystal daim ntawv) Foliar tshuaj tsuag lossis cov pa hluav taws xob uas zoo dua?

14-hydroxylated tooj dag yog lub ntuj broassinolide, uas yog dav siv nyob rau hauv ntau hom qoob loo.
Tam sim no, muaj ntau cov neeg txau txau cov qauv ntawm 14-hydroxylated tooj liab, tiv thaiv cov txiv hmab txiv ntoo thiab txo qhov kev pheej hmoo ntawm kev ua tshuaj tua kab.
Txawm li cas los xij, kev tshuaj tsuag foliaring tsuas tuaj yeem ua si 20% ntawm lub zog ntawm brassinolide. 14-hydroxylated broassinolide cov kab hauv dej tuaj yeem ua tau zoo dua nws lub luag haujlwm hauv kev txhawb nqa hauv paus kev txhim kho hauv paus, txhim kho thiab kev thauj mus los.

Cov hauv paus hniav yog ib qho ntawm 6 tus kab mob loj ntawm cov nroj tsuag.Lawv yog cov tseem ceeb ntawm cov qoob loo nqus thiab thauj cov dej thiab cov as-ham. Nyob rau tib lub sijhawm, lawv ua lub luag haujlwm tseem ceeb hauv kev khaws cia cov as-ham thiab kho cov qoob loo. Rau cov qoob loo, qhov tseem ceeb ntawm lub hauv paus system yog qhov pom tus kheej. Kev noj qab haus huv hauv paus hniav yog qhov yuav tsum tau ua ntej rau cov txiv hmab txiv ntoo muaj zog thiab noj qab haus huv. Ib lub zoo qoob loo sau yog raws ntawm "hauv paus".

Ntxiv rau kev kho thiab txhawb cov qoob loo, cov hauv paus hniav ntawm cov qoob loo kuj ua si plaub lub luag haujlwm tseem ceeb: kev nqus, synthesis, thiab cia. Cov qoob loo tsuas yog nqus cov dej thiab cov as-ham los ntawm cov hauv paus taub, thiab tom qab ntawd cov zaub mov thauj tau rau ntau yam txiv hmab thiab cov txiv hmab ntawm cov hauv paus hniav; Nyob rau tib lub sijhawm, ntau yam cov assients synthesized rau ntawm nplooj kuj tseem thauj mus rau ntau cov hormones cog ntau yam, thiab qee yam khaws cia hauv Parenchyma cov ntaub so ntswg ntawm cov hauv paus hniav.

Thaum lub hauv paus system puas ntsoog, kev nqus thiab kev sib haum xeeb thiab dej los ntawm cov qoob loo yog cuam tshuam ncaj qha, thiab cov synthesis ntawm cytokinins thiab ntau yam organic sib xyaw yog qeeb. Cov qoob loo ncaj qha yog tias cov qoob loo ncaj qha thiab muaj ntau yam cov tsos mob muaj txiaj ntsig zoo tshaj plaws, cuam tshuam nrog cov txiaj ntsig thiab cov qoob loo zoo.


14-hydroxylated Prassinolide txhawb txhawb txoj kev loj hlob hauv paus
14-hydroxylated tooj liab tuaj yeem txhawb txoj kev txhim kho hauv paus, thiab txhim kho cov dej ua haujlwm thiab ua kom muaj zog thiab cov as-ham los ntawm lub hauv paus system. 14-hydroxylated siv biostimulant pollen pinden polysaccharide ntawm cov hauv paus cov lus qhia ntawm cov qoob loo ntawm cov qoob loo thiab cov as-ham.

14-hydroxylated precassinolide txhim kho txoj kev nqus thiab kho
Tom qab cov qoob loo nqus cov as-ham los ntawm passive nqus thiab cov kev nqus tau, lawv tau thauj mus rau qhov chaw saum toj ntawm cov ntoo los ntawm cov ntoo. 14-hydroxylated broassinolide tuaj yeem ua kom muaj peev xwm nqus tau cov khoom muaj peev xwm los ntawm cov hauv paus hniav loj thiab kev txhawb nqa cov hauv paus system los thauj cov khoom noj rau cov chaw ua haujlwm saum toj no.

14-hydroxylated precassinolide txhim kho kev ntxias, tsis kam, acid thiab alkali, thiab kev tawm tsam mus rau ntuj qhuav.
Piv txwv li, kev ua chiv nyob rau lub caij ntuj no thiab lub caij nplooj ntoo hlav thaum ntxov tsis pom cov nyhuv nta zoo. Qhov laj thawj tseem ceeb yog qhov ntsuas kub yog tsawg dhau, ua rau cov nroj tsuag los ua dormant thiab tsis muaj qhov tseem ceeb. 14-hydroxylated broassinolide tuaj yeem txhim kho qib kev ua si thiab kev ua haujlwm medeess, thiab los ntawm kev txhim kho lub hauv paus haujlwm ntawm lub hauv paus system nyob rau hauv cov nyom ib puag ncig. Cov hauv paus hniav yog sib sib zog nqus thiab nplooj yog lush. Cov hauv paus hniav yog ib qho tseem ceeb tshaj plaws hauv cov qoob loo hauv cov qoob loo, thiab lawv qhov tseem ceeb yog tus kheej. Cov neeg ua liaj ua teb kuj tseem them ntau dua thiab ntau mloog rau kev noj qab haus huv ntawm cov hauv paus hniav. Raws li hom ntuj broassinolide, 14-hydroxylide Brassinolide tau pom ntev tau lees paub los ntawm cov neeg ua liaj ua teb thiab kev tiv thaiv hauv paus ua haujlwm. 14-hydroxylated tooj dag kuj tseem siv tau cov kev txhim kho dav.
