Vaega o le INDOLE-3-BUTYRIC ACID (IBA): INDOLE-3-BUTYRIC ACID (IBA) o se auxin endogenous lea e mafai ona faʻaleleia le vaevaega o sela ma le tuputupu aʻe o sela, faʻaosofia le faʻavaeina o aʻa faʻapitoa, faʻateleina seti fua, puipuia le pa'ū o fua, ma Suia fugala'au fafine ma tane Fuafuaga ma isi. E mafai ona ulu atu i le tino o la'au e ala i le epidermis mu'amu'a o lau, lala, ma fatu, ma felauai atu i vaega o lo'o galue fa'atasi ai ma le tafe o mea'ai.

Forchlorfenuron, e lauiloa foi o le KT-30, CPPU, ma isi, o se faʻatonuga o le tuputupu aʻe o laʻau faʻatasi ma le furfurylaminopurine aafiaga. O se fufurfurylaminopurine faʻapipiʻi faʻatasi ma le gaioiga sili ona maualuga i le faʻalauiloaina o le vaevaeina o sela. O lona gaioioiga olaola e tusa ma le benzylaminopurine 10 taimi, e mafai ona faʻaleleia le tuputupu aʻe o fualaʻau, faʻateleina le fuaina o fualaau aina, faʻalauteleina le faʻalauteleina o fualaau aina ma le faʻasaoina.

Thidiazuron (TDZ) o se faʻatonuga o le tuputupu aʻe o laʻau urea. E mafai ona fa'aoga i lalo ole tulaga maualuga ole gaogao, tamato gaosia, pepa ma isi fua. A maeʻa ona mitiia e laulaau o laʻau, e mafai ona faʻalauteleina laulaʻau vave, lea e aoga i le seleseleina masini. ; Faʻaoga i lalo o tulaga maualalo, e iai le cytokinin gaioiga ma e mafai ona faʻaaogaina i apu, pears, peaches, cherries, watermelons, melons ma isi fualaʻau e faʻateleina ai fua o fualaʻau fualaʻau, faʻalauteleina le faʻalauteleina o fualaau aina, ma faʻateleina fua ma le lelei.

Brassinolide (BR) e ese mai isi faʻatonuga o le tuputupu aʻe o laʻau i lona tasi-auala faʻatatau i le faʻalauiloaina o fua o fualaʻau ma faʻaleleia le lelei. Mo se faʻataʻitaʻiga, e le gata o loʻo i ai galuega faʻaletino o auxin ma cytokinin, ae o loʻo i ai foi le malosi e faʻateleina ai le photosynthesis ma faʻatonutonu le tufatufaina atu o meaʻai, faʻaleleia le felauaiga o gaʻo mai laʻau ma laulaau i fatu, faʻaleleia le teteʻe o fua i mea leaga i fafo, ma siitia le tuputupu ae o vaega vaivai o le laau. O le mea lea, e matua lautele le faʻaaogaina ma le faʻatinoga.
