Uburyo bwibikorwa byaIAA (Indole-3-Acide Acide) ni uguteza imbere kugabana, kurambura no kwaguka.

Ubushuhe buke na aside ya Gibberellic hamwe nindi miti yica udukoko bifatanyiriza hamwe guteza imbere imikurire niterambere ryibimera.Kwibanda cyane bitera umusaruro wa endogenous etylene kandi bigatera gukura no gusaza kwingirangingo cyangwa ingingo.

Nibintu byambere byashinze imizi bikoreshwa mubuhinzi kandi bigari-bigari byinshi bigamije gukura kw'ibimera.Ariko byangirika byoroshye imbere no hanze yikimera.

Ibikorwa shingiro byimikorere yaIBA (Indole-3-Acide Butyric)birasa na IAA (Indole-3-Acide Acide).Nyuma yo gutwarwa nibimera, ntabwo byoroshye kwitwara mumubiri, kandi akenshi biguma mubice bivura, bityo bikoreshwa cyane mugutezimbere imizi yibiti.Nubwo ihagaze neza kuruta aside irike, biroroshye kubora iyo ihuye numucyo.

Gukoresha inshuro imwe bigira ingaruka kumizi yibihingwa bitandukanye, ariko bivanze nibindi bigenga imikurire yikimera bifite ingaruka zo gushinga imizi, ingaruka nibyiza.Kurugero,IAA or IBAikoreshwa mugutezimbere imizi myiza, idakabije kandi ishami amashami iyo gutema gushinga imizi;NAA (Acide Naphthylacetic)Irashobora gutera imizi, endoplasmeque imizi myinshi-ishami, nibindi, bityo guhuza kwabo gukoreshwa kenshi mubikorwa.
