I-sodium o-nitrophenolate ingasetyenziselwa njenge-activator yeseli yesityalo, enokuthi ingene ngokukhawuleza emzimbeni wesityalo, ikhuthaze ukuhamba kweprotoplasm yeseli, kwaye ikhawuleze isantya se-rooting yezityalo.

Iindidi eziphambili zeengcambu zesityalo kunye nee-agent zokwandisa i-stem ziquka i-chlorformamide kunye ne-choline chloride/naphthyl acetic acid.

I-Choline chloride yi-synthetic yezityalo zokulawula ukukhula ezinokukhuthaza ukwanda ngokukhawuleza kweengcambu eziphantsi komhlaba kunye neengcambu, ukuphucula isivuno kunye nomgangatho. . Iyakwazi nokulawula i-photosynthesis yamagqabi kwaye inqanda ukuphefumla kwefoto, ngaloo ndlela ikhuthaza ukwandiswa kwee-tubers eziphantsi komhlaba.

Izilawuli zokukhula kwezityalo ezikhuthaza ukukhula kwangethuba kwezityalo ikakhulu ziquka ezi ndidi zilandelayo:I-Gibberellic Acid (GA3): I-Gibberellic Acid silawuli sokukhula kwesityalo esibanzi esinokukhuthaza ukukhula nophuhliso lwezityalo, sizenze zivuthwe kwangoko, zandise isivuno, kunye nokuphucula umgangatho. Ilungele izityalo ezinjengomqhaphu, iitumato, imithi yeziqhamo, iitapile, ingqolowa, iimbotyi zesoya, icuba kunye nerayisi.

Ukucatshulwa kwesityalo lelinye lamanqanaba abalulekileyo okukhula kwezityalo kwaye libaluleke kakhulu ekukhuleni, ekuphuhliseni nasekuveliseni izityalo. Ngoko ke, indlela yokukhuthaza ingcambu yezityalo ngumba obalulekileyo ekulinyweni kwezityalo. Eli nqaku liza kuxubusha indlela yokukhuthaza ukuhluma kwezityalo kwimiba yeemeko zesondlo, iimeko zokusingqongileyo, kunye neendlela zonyango.
