INaphthalene acetic acid (NAA) sisilawuli sokukhula kwesityalo sokwenziwa sodidi lwenaphthalene yeekhompawundi. Yikristale engenambala eqinileyo, enyibilikayo emanzini nakwizinyibilikisi zendalo. INaphthalene acetic acid (NAA) isetyenziswa kakhulu kwinkalo yolawulo lokukhula kwezityalo, ingakumbi idlala indima ebalulekileyo ekukhuleni nasekuphuhliseni imithi yeziqhamo, imifuno kunye neentyatyambo.

I-Chlormequat chloride (CCC) ngumchasi we-gibberellins.Umsebenzi wayo oyintloko kukuthintela i-biosynthesis ye-gibberellins.Inokuthintela ukunyuswa kweeseli ngaphandle kokuchaphazela ukuhlukana kweeseli, inqanda ukukhula kweziqu kunye namaqabunga ngaphandle kokuchaphazela ukuphuhliswa kwezitho zesini, ngaloo ndlela ifezekisa ulawulo. yobude, ukuxhathisa indawo yokuhlala kunye nokwandisa isivuno.

I-Gibberellic acid (GA3) inokukhuthaza ukuntshula kwembewu, ukukhula kwesityalo, kunye nokuqhama kwangethuba kunye nokuqhama. Isetyenziswa ngokubanzi kwiintlobo ngeentlobo zezityalo zokutya, kwaye isetyenziswa ngokubanzi kwimifuno.Inempembelelo ebalulekileyo yokukhuthaza kwimveliso kunye nomgangatho wezityalo kunye nemifuno.
