Thaum nws los txog rau cov tshuaj tua cov cag, kuv paub tseeb tias peb txhua tus paub txog lawv. Cov uas feem ntau suav nrog naphthaleneacetic acid,IAA 3-indole acetic acid, IBA 3-Indolebutyric-acid, thiab lwm yam. Tab sis koj puas paub qhov txawv ntawm indolebutyric acid thiab indoleacetic acid?
【1】Cov peev txheej sib txawv
IBA 3-Indolebutyric-acid yog ib yam tshuaj hormones endogenous hauv cov nroj tsuag. Nws qhov chaw nyob hauv cov nroj tsuag thiab nws tuaj yeem tsim tau hauv cov nroj tsuag.IAA 3-indole acetic acidyog ib yam khoom uas tsim los ntawm kev dag, zoo ib yam li IAA, thiab tsis muaj nyob hauv cov nroj tsuag.
【2】Lawv cov khoom siv lub cev thiab tshuaj lom neeg sib txawv
IAA 3-indole acetic acid ntshiab yog ib qho tsis muaj xim zoo li nplooj siv lead ua los yog hmoov crystalline. Nws yooj yim yaj hauv anhydrous ethanol, ethyl acetate thiab dichloroethane, yaj hauv ether thiab acetone, thiab tsis yaj hauv benzene, toluene, roj av thiab chloroform.
IBA 3-Indolebutyric-acid yog soluble nyob rau hauv cov organic solvents xws li acetone, ether thiab ethanol, tab sis tsis zoo soluble nyob rau hauv dej.
【3】Kev ruaj khov sib txawv:
Cov txheej txheem ua haujlwm ntawm IAA 3-indole acetic acid thiabIBA 3-Indolebutyric-acidyeej zoo sib xws. Lawv tuaj yeem txhawb kev faib cell, kev ntev thiab kev nthuav dav, ua rau muaj kev sib txawv ntawm cov ntaub so ntswg, txhim kho qhov permeability ntawm cov cell membranes, thiab ua kom cov protoplasm ntws sai dua. Txawm li cas los xij, IBA 3-Indolebutyric-acid ruaj khov dua li IAA 3-indole acetic acid, tab sis nws tseem yooj yim rau decomposition thaum raug lub teeb. Nws yog qhov zoo dua los khaws cia kom deb ntawm lub teeb.
【4】Cov tshuaj sib xyaw ua ke:
Yog tias cov tshuaj tswj tau sib xyaw ua ke, cov nyhuv yuav zoo ib yam lossis zoo dua. Yog li ntawd, nws tseem pom zoo kom sib xyaw nrog cov khoom zoo sib xws, xws li sodium naphthoacetate, sodium nitrophenolate, thiab lwm yam.
