Indole-3-acetic acid CAS 87-51-4
Indole-3-acetic acid, tseem hu ua auxin, yog ib qho tshuaj uas tswj kev loj hlob ntawm cov nroj tsuag thiab yog ib qho hmoov dawb crystalline. Indole-3-acetic acid yaj tau hauv acetone thiab ether, yaj me ntsis hauv chloroform, thiab tsis yaj hauv dej. Tau los ntawm kev sib xyaw indole nrog hydroxyacetic acid. Indole-3-acetic acid yog siv los ua ib qho tshuaj uas tswj kev loj hlob ntawm cov nroj tsuag, uas tuaj yeem txhawb kev faib cell, ua kom cov hauv paus hniav sai dua, ua kom cov txiv hmab txiv ntoo loj hlob sai dua, thiab tiv thaiv cov txiv hmab txiv ntoo poob.

Indole-3-acetic acid yog ib qho tshuaj uas tswj kev loj hlob ntawm cov nroj tsuag dav dav nrog indole-3-acetic acid thiab auxin ua haujlwm; Tswj cov hluav taws xob thiab proton channel ntawm lub cell membrane. Siv ua ib qho tshuaj uas tswj kev loj hlob ntawm cov nroj tsuag, nws tuaj yeem txhawb kev faib cell, ua kom cov hauv paus hniav sai dua, ua kom cov txiv hmab txiv ntoo loj hlob sai dua, thiab tiv thaiv cov txiv hmab txiv ntoo poob. Tus ua ntej ntawm Indole-3-acetic acid biosynthesis hauv cov nroj tsuag yog tryptophan. Lub luag haujlwm tseem ceeb ntawm auxin yog tswj kev loj hlob ntawm cov nroj tsuag, tsis yog tsuas yog txhawb kev loj hlob xwb, tab sis kuj tseem tiv thaiv kev loj hlob thiab kev tsim cov kab mob.
Feem ntau ntim rau hauv 5kg / nruas, thiab kuj tuaj yeem ua pob khoom raws li koj xav tau.
