Indlela yokusebenza yeI-IAA (Indole-3-Acetic Acid) ukukhuthaza ukuhlukana kwamaseli, ukunwetshwa kanye nokwanda.

Ukuhlushwa okuphansi kanye ne-Gibberellic acid nezinye izibulala-zinambuzane zikhuthaza ukukhula nokuthuthukiswa kwezitshalo.Ukugxila okuphezulu kudala ukukhiqizwa kwe-ethylene engapheli futhi kukhuthaza ukuvuthwa kanye ne-senescence yezicubu zezitshalo noma izitho.

Yi-ejenti yokuqala yokutshala izimpande esetshenziswa kwezolimo kanye nesilawuli sokukhula kwezitshalo esinezinjongo eziningi.Kodwa wonakaliswa kalula ngaphakathi nangaphandle kwesitshalo.

Imisebenzi eyisisekelo ye-physiologicalI-IBA (Indole-3-Butyric Acid)zifana ne-IAA (Indole-3-Acetic Acid).Ngemva kokumuncwa izitshalo, akulula ukuqhuba emzimbeni, futhi ngokuvamile kuhlala engxenyeni yokwelapha, ngakho-ke isetshenziselwa ikakhulukazi ukukhuthaza ukuqothulwa kwe-cuttings.Nakuba izinzile kune-indole acetic acid, kulula ukubola uma ibekwe ekukhanyeni.

Ukusetshenziswa okukodwa kunomphumela wokukhula kwezimpande ezitshalweni ezihlukahlukene, kodwa kuhlanganiswe nezinye izilawuli zokukhula kwezitshalo ezinomphumela we-rooting, umphumela ungcono.Ngokwesibonelo,IAA or IBAisetshenziselwa ukukhuthaza izimpande ezinhle, ezincane futhi ezinamagatsha lapho ukusika kumila;I-NAA (Naphthylacetic Acid)ingadala izimpande eziwugqinsi, ezinamagatsha amaningi e-endoplasmic, njll., ngakho-ke inhlanganisela yazo ivame ukusetshenziswa ekukhiqizeni.
