Khoom piav qhia:

Indole -3-Butyric Acid (IBA)

CAS Nr.: 133-32-4

Cov mis mos molecular: C12H13NO2

Molecular Luj: 203.2

 

Muaj nuj nqi:

Indole-3-Butyric Acid (IBA) muaj kev ruaj ntseg zoo dua li ntawm lAA thiab tsis tuaj yeem yooj yim decomposed los ntawm AA oxidase. IBA kuj tseem muaj sijhawm ntev ntawm bio-kev ua haujlwm.

IBA yog cov nroj tsuag tseem ceeb hauv paus cov khoom uas tuaj yeem nqus tau los ntawm cov hauv paus, qia, nplooj thiab txiv hmab txiv ntoo. Nws yog siv los pib tsim cov hauv paus hniav thiab nws tuaj yeem ua rau lub hauv paus adventitious kom loj hlob thiab txhawb rooting ntawm txiav twigs.

lBA yog ib qho dav-spectrum auxin cog kev loj hlob regulator uas tuaj yeem txhim kho cov ntsiab lus ntawm chlorophyll, protein thiab nucleic acid hauv cov nroj tsuag. Lub sijhawm no, nws txhim kho kev ua haujlwm ntawm photosynthesis.

Indole-3-Butyric Acid (IBA) tuaj yeem ua rau cov txiv hmab txiv ntoo muaj txiaj ntsig thiab txo qis abscission ntawm cov txiv hmab txiv ntoo. Kho qhov piv ntawm staminate thiab pistillate paj.

IBA tuaj yeem ua ke nrog cov chiv thiab txhim kho kev nqus ntawm cov chiv zoo heev.
