O a fugala'au fa'atonutonu?
O lenei ituaiga o fugala'au o lo'o i ai mea e fa'atonutonu ai le tuputupu a'e o la'au, e pei o le auxin, hormones ma isi mea.
O lana galuega autu o le faʻatonutonuina o le tuputupu aʻe ma le atinaʻe. E fetaui lelei mo le faʻaaogaina i le amataga ma le ogatotonu o le tuputupu aʻe o laʻau.
I le faagasologa o le tuputupu aʻe, e le gata ina faʻapipiʻiina e laau le tele o meaʻai ma mea faʻavae, ae e maua ai foʻi ni mea faʻapitoa faʻaletino, e taʻua o hormones o laau toto. E ui lava o nei hormones o loʻo i ai i ni vaega laiti i totonu o laʻau, e mafai ona latou faʻatonutonuina ma pulea le tuputupu aʻe masani ma le atinaʻeina o laʻau, e pei o le tuputupu aʻe o le sela ma le eseesega, vaevaega o le cell, fausiaina o okeni, moe ma germination, tropism laau, lagona, matua, faamaligiina, matua, ma isi, o ia mea uma e faʻatonutonu saʻo pe leai foi e hormones. O nisi o mea fa'aletino fa'akomepiuta fa'apipi'iina i totonu o falegaosimea e tutusa o latou fausaga mole mole ma a'afiaga fa'aletino i hormones fa'alenatura o la'au ua ta'ua o le fa'atonuina o le tuputupu a'e o la'au.
O faʻatonuga o le tuputupu aʻe o laʻau ma hormones o laʻau e masani ona taʻua faʻatasi o le faʻatonutonuina o le tuputupu aʻe o laau.
I le taimi nei, o lo'o fa'aaogaina fa'atonuga o le tuputupu a'e o la'au i le gaosiga o
①Ausin:pei ole Naphthalene acetic acid (NAA), Indole-3-acetic acid, anti-drop agent, 2,4-D, ma isi;
②Gibberellic Acid:E tele ituaiga o Gibberellic Acid compounds, ae o le Gibberellic Acid o loʻo faʻaaogaina i le gaosiga e masani lava (GA3) ma GA4, GA7, ma isi;
③Cytokinins:pei o le 5406;
④Ethylene:Etefona;
⑤Totoga tuputupu aʻe inhibitors poʻo faʻalavelave:Chlormequat Chloride (CCC), chlorambucil, Paclobutrazol (Paclo), palasitika, ma isi. I le faaopoopo atu i luga, o loʻo i ai Brassinolide (BRs), zeati, abscisic acid, defoliants, triacontanol, ma isi.
