Ekukhiqizweni kwezihlahla zezithelo, i-Gibberellic Acid (GA3) isetshenziswa kakhulu ukunqamula ukuhlala kwembewu noma imiqumbe ezinhlotsheni ezithile zezihlahla, ngaleyo ndlela kugqugquzelwe ukuhluma okusheshayo kanye nokunciphisa isikhathi sokwelashwa kwembewu ukuze kuthuthukiswe ukuhluma nokwandisa izinga lokuhluma.

I-Indole-3-Butyric Acid (IBA) kanye ne-1-Naphthyl Acetic Acid (NAA) Le nhlanganisela ijwayele ukusetshenziselwa ukusikwa noma izitshalo ezitshalwe kabusha. Isibonelo, i-5% IBA·NAA powder encibilikayo (equkethe i-2.5% IBA kanye ne-2.5% NAA) ingenza kusebenze ukuhlukaniswa kwamaseli futhi ikhuthaze ukwakheka kwe-root primordia

I-Zeatin igqugquzela ukuhlukaniswa kwamaseli futhi ingathinta ezinye izigaba zomjikelezo weseli. Imisebenzi yayo ifaka phakathi ukuvikela i-chlorophyll kanye ne-protein devalation, ukunciphisa ukuphefumula, ukulondolozela ubungqabavu seseli, ukumbumbuluzwa kwesitshalo se-censecence, kubuyisela imiphumela enobuthi emaqabungeni, kuvimbela ukwakheka kwezimpande, nokukhuthaza ukwakheka kwe-thwebula ngokugxila okuphezulu.

I-Brassinolide ye-Hydroxylated ingasebenza ngokunembile esigabeni ngasinye sokukhula kwesitshalo: Ukukhuthaza izimpande kanye nokukhula kwesithombo ngesikhathi sesithombo se-sithombo, ukuvikela izimbali ngesikhathi sezimbali, ukuvumela izilimo ngesikhathi esifanele.
