Lub mechanism ntawm kev ua ntawmIAA (Indole-3-Acetic Acid) yog los txhawb cell division, elongation thiab expansion.

Tsawg concentration thiab Gibberellic acid thiab lwm yam tshuaj tua kab synergistically txhawb kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag.High concentration induces zus tau tej cov endogenous ethylene thiab txhawb lub maturation thiab senescence ntawm cov nroj tsuag cov ntaub so ntswg los yog lub cev.

Nws yog tus thawj rooting neeg sawv cev siv nyob rau hauv kev ua liaj ua teb thiab ib tug dav-spectrum multi-purpose cog kev loj hlob regulator.Tab sis nws yog yooj yim degraded sab hauv thiab sab nraum cov nroj tsuag.

Basic physiological functions ntawmIBA (Indole-3-Butyric Acid)zoo ib yam li IAA (Indole-3-Acetic Acid).Tom qab nqus los ntawm cov nroj tsuag, nws tsis yooj yim rau kev coj ua hauv lub cev, thiab feem ntau nyob twj ywm hauv kev kho mob, yog li nws yog siv los txhawb cov rooting ntawm cuttings.Txawm hais tias nws ruaj khov dua li indole acetic acid, nws yooj yim rau decompose thaum raug teeb.

Kev siv ib leeg muaj cov nyhuv hauv paus rau ntau yam qoob loo, tab sis tov nrog lwm cov nroj tsuag kev loj hlob regulators nrog rooting nyhuv, cov nyhuv yog zoo dua.Piv txwv li,IAA or IByog siv los txhawb kev nplua, sparse thiab branched keeb kwm thaum cuttings noj paus;Naphthylacetic Acid (NAA)tuaj yeem ua rau cov ntoo tuab, endoplasmic multi-branched keeb kwm, thiab lwm yam, yog li lawv cov kev sib xyaw ua ke feem ntau siv hauv kev tsim khoom.
