Yintoni umahluko phakathi kwe-IBA 3-Indolebutyric-acid acid kunye ne-IAA 3-indole acetic acid?

Xa kufikwa kwiiarhente zokugquma iingcambu, ndiqinisekile ukuba sonke siyazazi. Eziqhelekileyo ziquka i-naphthaleneacetic acid,IAA 3-indole acetic acid, I-IBA 3-Indolebutyric-acid, njl. Kodwa ngaba uyazi umahluko phakathi kwe-indolebutyric acid kunye ne-indoleacetic acid?

【1】Imithombo eyahlukeneyo

I-IBA 3-Indolebutyric-acid yi-hormone ephilayo kwizityalo. Umthombo wayo ukwizityalo kwaye inokuveliswa kwizityalo.IAA 3-indole acetic acidyinto eyenziwe ngokwenziwa, efana ne-IAA, kwaye ayikho kwizityalo.

【2】Iimpawu zabo zomzimba nezekhemikhali zahlukile

I-acetic acid ye-IAA 3-indole ecocekileyo yi-crystal okanye i-crystalline powder engenambala efana negqabi. Inyibilika lula kwi-anhydrous ethanol, i-ethyl acetate kunye ne-dichloroethane, inyibilika kwi-ether kunye ne-acetone, kwaye ayinyibiliki kwi-benzene, i-toluene, ipetroli kunye ne-chloroform.

I-IBA 3-Indolebutyric-acid iyanyibilika kwizinyibilikisi ze-organic ezifana ne-acetone, i-ether kunye ne-ethanol, kodwa ayinyibiliki kakuhle emanzini.

【3】Uzinzo olwahlukileyo:

Iindlela zokusebenza kwe-IAA 3-indole acetic acid kunyeI-IBA 3-Indolebutyric-acidziyafana ngokusisiseko. Zinokukhuthaza ukwahlukana kweeseli, ukwandiswa kunye nokwandiswa, zibangele ukwahluka kwezicubu, zonyuse ukuvuleka kwee-membranes zeseli, kwaye zikhawulezise ukuhamba kwe-protoplasm. Nangona kunjalo, i-IBA 3-Indolebutyric-acid izinzile ngakumbi kune-IAA 3-indole acetic acid, kodwa isenokonakala xa ivezwa ekukhanyeni. Kungcono ukuyigcina kude nokukhanya.

【4】Amalungiselelo e-compound:

Ukuba abalawuli baxutyiwe, isiphumo siya kuba ngaphezulu okanye sibe ngcono nangakumbi. Ke ngoko, kusacetyiswa ukuba kuxutyiwe ngeemveliso ezifanayo, ezifana ne-sodium naphthoacetate, i-sodium nitrophenolate, njl.
