Yimuphi umehluko phakathi kwe-IBA 3-Indolebutyric-acid acid kanye ne-IAA 3-indole acetic acid?

Uma kukhulunywa ngezinto ezisusa izimpande, ngiyaqiniseka ukuthi sonke siyazazi. Ezivamile zihlanganisa i-naphthaleneacetic acid,IAA 3-indole acetic acid, I-IBA 3-Indolebutyric-acid, njll. Kodwa uyawazi umehluko phakathi kwe-indolebutyric acid kanye ne-indoleacetic acid?

【1】Imithombo ehlukene

I-IBA 3-Indolebutyric-acid iyi-hormone engokwemvelo ezitshalweni. Umthombo wayo usezitshalweni futhi ingakhiwa ezitshalweni.IAA 3-indole acetic acidkuyinto eyenziwe ngokwenziwa, efana ne-IAA, futhi ayikho ezitshalweni.

【2】Izakhiwo zabo zomzimba nezamakhemikhali zihlukile

I-Pure IAA 3-indole acetic acid iyi-crystal noma i-crystalline powder engenambala efana neqabunga. Incibilika kalula ku-anhydrous ethanol, i-ethyl acetate kanye ne-dichloroethane, incibilika ku-ether kanye ne-acetone, futhi ayincibiliki ku-benzene, i-toluene, uphethiloli kanye ne-chloroform.

I-IBA 3-Indolebutyric-acid iyancibilika ezinyibilikisini eziphilayo ezifana ne-acetone, i-ether kanye ne-ethanol, kodwa ayincibiliki kahle emanzini.

【3】Ukuqina okuhlukile:

Izindlela zokusebenza kwe-IAA 3-indole acetic acid kanyeI-IBA 3-Indolebutyric-acidziyafana ngokuyisisekelo. Zingakhuthaza ukuhlukana kwamaseli, ukunwebeka nokukhula, zibangele ukuhlukaniswa kwezicubu, zithuthukise ukungena kwama-membranes amaseli, futhi zisheshise ukugeleza kwe-protoplasm. Kodwa-ke, i-IBA 3-Indolebutyric-acid izinzile kakhulu kune-IAA 3-indole acetic acid, kodwa isathambekele ekuboleni uma ivezwa ekukhanyeni. Kungcono ukuyigcina kude nokukhanya.

【4】Amalungiselelo ahlanganisiwe:

Uma abalawuli behlanganiswa, umphumela uzobekwa ngaphezulu noma ube ngcono nakakhulu. Ngakho-ke, kusanconywa ukuthi kuhlanganiswe nemikhiqizo efanayo, njenge-sodium naphthoacetate, i-sodium nitrophenolate, njll.
