Umthelela wezilawuli zokukhula kwezitshalo uthintwa yizici eziningi, okuhlanganisa izinhlobo zezitshalo, izigaba zokukhula, amasayithi okusebenza, izinhlobo zokulawula, ukugxilisa ingqondo, izindlela zokufaka isicelo, kanye nezindawo zangaphandle. Enqubweni yokusebenzisa izilawuli zokukhula kwezitshalo, inkinga yokulimala kwezibulala-zinambuzane ivelele kakhulu. Lesi sihloko sizohlaziya izimbangela zokulimala kwesilawuli sokukhula kwezitshalo ngamakesi amahlanu wangempela wokulimala kwezibulala-zinambuzane.

zezitshalo. Bangakwazi ukukhuthaza noma ukuvimbela ukukhula nokuthuthukiswa kwezitshalo ezindaweni eziphansi. Ngaphakathi kwesigaba sezibulala-zinambuzane, izilawuli zokukhula kwezitshalo zingenye yekhetheke kakhulu. Izinzuzo zezilawuli zokukhula kwezitshalo njengokuthi "umthamo ophansi, umphumela obalulekile, kanye nesilinganiso esiphezulu somkhiqizo wokufakwayo" kwenza lolu hlobo lwesibulala-zinambuzane lube yimpahla ebalulekile yokukhiqiza ekutshalweni kwemifino esikhungweni esingekho isizini.

I-sodium o-nitrophenolate ingasetshenziswa njenge-activator yeseli yezitshalo, engangena ngokushesha emzimbeni wesitshalo, ikhuthaze ukugeleza kwe-protoplasm yeseli, futhi isheshise isivinini sokukhula kwezitshalo.

Izinhlobo eziyinhloko zezimpande zesitshalo kanye nama-ejenti okukhulisa isiqu zifaka i-chlorformamide ne-choline chloride/naphthyl acetic acid.

I-Choline chloride iyisilawuli sokwenziwa sokukhula kwezitshalo esingakhuthaza ukwanda ngokushesha kwezimpande nezilimo eziyizigaxa ezingaphansi komhlaba, ukuthuthukisa isivuno kanye nekhwalithi. . Ingakwazi futhi ukulawula i-photosynthesis yamaqabunga futhi ivimbele i-photorespiration, ngaleyo ndlela ikhuthaze ukwanda kwezilimo eziyizigaxa ezingaphansi komhlaba.
