O le faʻatupulaia o le totoina o meaola o se taimi lautele mo se vasega o vailaʻau vailaʻau gaosi o loʻo i ai se faʻatonutonu aafiaga i le totoina o laʻau ma atinaʻe. E faʻatonutonuina fualaʻau e aofia ai le gagauina o le moe, faʻalauiloaina germination, faʻalauteleina lala ma laʻau tuputupu aʻe, faʻalauiloa fuga fugalaʻau, faʻalauiloaina fua fualaʻau, fausiaina Seedless fualaʻau ma taofia le tuputupu aʻe o laʻau laʻau ma fualaʻau, ma isi., tusa ai ma mea moni gaosiga manaʻoga, fetuutuunai faʻaaogaina o tulafono faʻatonutonu o le taua o lona uiga ia faʻateleina ma mautu fua. E i ai foi le lelei o le "maualalo metotia, taua aafiaga, ma maualuga sao-galuega faatino fuafaatatau"

E lua ituaiga: ilant homone ma laʻau faʻatupulaia tuputupu aʻe. O homone toto o meaola niniʻi lava o le tino o loʻo tuʻufaʻatasia i laʻau, e masani ona feaveaʻi mai le nofoaga o faʻasologa i le nofoaga e fai ai gaioiga, ma e tele sona aʻafiaga faʻatonutonu ile faʻatupulaia ma le atinaʻeina o laʻau. O mea e faʻatupuina le totoina o laʻau e gaosia tuʻufaʻatasia pe toʻesea mai i meaola ninii. E i ai a latou gaioiga tutusa pe tutusa ma homone o laʻau. E mafai ona latou faʻatonutonu, faʻatonutonu, faʻatonutonu ma faʻamalosia le tuputupu aʻe ma le atinaʻeina o faʻatoʻaga faʻapea foi ma homone e gata ai. I le taimi nei, e selau ma selau o faʻasolosolo faʻasolosolo laʻau faʻatupuina totoina faʻatonutonu, nisi olatou sa masani ona faʻaaogaina i faʻatoʻaga gaosiga. O le laautuputupu aʻe tulafono faʻatonutonu ua mauaina e masani ona aofia ai ono ituaiga, lea e Auxin, Gibberellin, Cytokinin, Abscisic, Acid Ethylene ma Brassin

Faʻaogaina o laʻau totoʻa tulafono faʻatonutonu

I tulaga o eseʻese faʻaaogaina, faʻalauteleina le mauaa ma faʻalauiloa aʻa tipitaʻu masani faʻaaoga 3-indole acetic acid (IAA), 3-indole butyric acid (IBA), 1-naphthalene acetic acid (NAA), ma le ABT rooting efuefu. B9, paclobutrazol, chlormequat, ma le ethephon faʻaaoga e faʻatuai ai le tuputupu aʻe. Gibberellin masani ona faʻaaoga i faʻalauteleina le tuputupu ae o au ma laulaʻau, fai totoina ma fugalaʻau muamua, faʻalauteleina le germination o fatu ma tubers, faʻaosofia ai le tuputupu aʻe o fualaʻau, faʻateleina fua o fua, pe fausia fualaʻau e leai ni fatu, ma isi.. Latou have sa tele na faʻaaogaina i le galueaina o pateta, tamato, araisa, saito, vavae, soybean, pi, tapaa, fualaʻau ma isi faʻatoaga.

I le taimi nei, e i ai tele ituaiga o laʻau tuputupu aʻe faʻatonutonu resitaraina ma faʻaaogaina i Saina. O a latou galuega autu o: faʻaʻumiʻumi teuina okeni dormancy / talepe potu moe ma faʻalauiloa germination, faʻalauteleina rooting, faʻalauteleina / taofiofia le tuputupu ae o laʻau ma laʻau laʻau, faʻalauiloaina / taofia le faʻavaeina o fugalaʻau, manifinifi / faasaoina o fugalaʻau ma fualaʻau, faʻagaeʻetia fafine fugalaʻau / tama fugalaʻau, faʻalauteleina taimi fugalaʻau, tausia tipiina fugalaʻau fou, fausiaina leai ni fatu, faʻalauiloaina fualaʻau fualaʻau, faʻalauteleina / tolopoina matua fualaʻau, tolopoina senencence, faʻateleina amino acid / polotini mataupu / suka mataupu, faʻateleina fi mea o loʻo i totonu, faʻaleleia le teteʻeina o faʻafitauli, ma isi.
