I-Naphthalene acetic acid (NAA) iyisilawuli sokukhula kwesitshalo sokwenziwa esesigaba se-naphthalene sezinhlanganisela. Kuyikristalu eqinile engenambala, encibilika emanzini nasezincibilikisini eziphilayo. I-Naphthalene acetic acid (NAA) isetshenziswa kakhulu emkhakheni wokulawula ukukhula kwezitshalo, ikakhulukazi idlala indima ebalulekile ekukhuleni nasekuthuthukisweni kwezihlahla zezithelo, imifino kanye nezimbali.

I-Chlormequat chloride (CCC) iphikisana ne-gibberellins.Umsebenzi wayo oyinhloko ukuvimbela i-biosynthesis ye-gibberellins.Ingakwazi ukuvimbela ukuphakama kwamaseli ngaphandle kokuthinta ukuhlukana kwamaseli, ivimbele ukukhula kweziqu namaqabunga ngaphandle kokuthinta ukuthuthukiswa kwezitho zocansi, ngaleyo ndlela ifinyelele ukulawula. of elongation, ukumelana nendawo futhi andise isivuno.

I-Gibberellic acid (GA3) ingakhuthaza ukuhluma kwembewu, ukukhula kwezitshalo, kanye nokuqhakaza kokuqala kanye nokuthela. Isetshenziswa kabanzi ezitshalweni ezihlukene zokudla, futhi isetshenziswa kakhulu emibhideni.Inomphumela obalulekile wokukhushulwa ekukhiqizeni kanye nekhwalithi yezitshalo nemifino.
