The mechanism of action ofIAA (Indole-3-Acetic Acid) ndeyekusimudzira kupatsanurwa kwesero, kurebesa uye kuwedzera.

Low concentration uye Gibberellic acid nemamwe mishonga yekuuraya zvipembenene synergistically inosimudzira kukura nekukura kwezvirimwa.Yakanyanya kutarisisa inokonzeresa kugadzirwa kwe endo native ethylene uye inosimudzira matutu uye senescence yezvidyarwa tishu kana nhengo.

Ndiyo yekutanga midzi mumiriri inoshandiswa mukurima uye yakafara-mazhinji-chinangwa chekukura chirimwa regulator.Asi zviri nyore kuderedzwa mukati uye kunze kwechirimwa.

The basic physiological mabasa eIBA (Indole-3-Butyric Acid)zvakafanana neIAA (Indole-3-Acetic Acid).Mushure mekubatwa nemiti, hazvisi nyore kuitisa mumuviri, uye kazhinji inogara muchikamu chekurapa, saka inonyanya kushandiswa kukurudzira midzi yekucheka.Kunyangwe yakagadzikana kupfuura indole acetic acid, iri nyore kuora kana yaiswa muchiedza.

Kushandiswa kumwe chete kune midzi yemidzi pazvirimwa zvakasiyana, asi zvakasanganiswa nemamwe magadzirirwo ekukura kwezvirimwa ane rooting effect, mhedzisiro yacho iri nani.Semuyenzaniso,IAA or IBAinoshandiswa kusimudzira midzi yakanaka, shoma uye ine matavi apo midzi inocheka;NAA (Naphthylacetic Acid)inogona kupinza gobvu, endoplasmic akawanda-matavi midzi, nezvimwewo, saka musanganiswa wavo unowanzoshandiswa mukugadzira.
