O le faʻatonuina o le tuputupu aʻe e fa, Paclobutrazol, Uniconazole, Chlormequat Chloride, ma le Mepiquat chloride, e pulea uma le tuputupu aʻe o laau i se taimi puupuu e ala i le taofia o le faʻaogaina o le Gibberellic acid i totonu o laʻau. I

Paclobutrazole (Paclo) e faʻaaogaina i fualaʻau eseese e pei o araisa, saito, fualaau faisua, ma fualaau aina. Paclobutrazole (Paclo) ose la'au fa'asa'o fa'atupula'ia. E mafai ona faʻalavelaveina le tuʻufaʻatasia o gibberellins endogenous i totonu o laʻau ma faʻaitiitia le vaeluaina ma le faʻalauteleina o sela laau.

Compound sodium nitrophenolate (Atonik) o se faʻatonuga o le tuputupu aʻe o laau toto maualuga. E i ai uiga o le maualuga maualuga, leai se afaina, leai se toega, ma le lautele o le faʻaogaina o laina. E taʻua o le "Green Food Engineering Recommended Plant Growth Regulator" e le Faalapotopotoga o Taumafa ma Faatoaga Faavaomalo. leai ni a'afiaga i tagata ma manu.

Thidiazuron (TDZ) o se meaʻai masani e aofia ai le faʻafefiloi o le potassium dihydrogen phosphate ma le thiadiazuron. E tele aʻafiaga i luga o le tuputupu aʻe ma le atinaʻeina o fualaau aina: faʻateleina fua, faʻaleleia le lelei, faʻaleleia o faʻamaʻi faʻamaʻi, ma isi.
