I-Prohexadione calcium iyisilawuli sokukhula kwezitshalo esisebenza kakhulu esingasetshenziswa ukulawula ukukhula nokuthuthukiswa kwezilimo eziningi futhi ivame ukusetshenziswa ekukhiqizweni kwezolimo.

Isebenza kanjani i-Brassinolide

I-Brassinolide isilawuli sokukhula kwezitshalo esikhuthaza ukukhula kwezitshalo nokuqhakaza kanye nokuthela. Umgomo wayo wesenzo uthi: I-Brassinolide ingashukumisa ukuhlukana kwamangqamuzana ezitshalo nokwandisa, isheshise ukuhlukaniswa kwamaseli kanye nokukhula kwezicubu.

I-Gibberellic Acid GA3 yokugxilisa imbewu yokucwiliswa kwembewu nokuhluma

I-Gibberellic Acid GA3 iyisilawuli sokukhula kwezitshalo. Ukugxila okusetshenziselwa ukucwiliswa kwembewu nokuhluma kuzothinta ngqo umphumela wokuhluma. Ukugxila okuvamile ngu-100 mg/L.
