I-Thidiazuron (TDZ) iyisilawuli sokukhula kwesitshalo se-urea. Ingasetshenziswa ngaphansi kwezimo eziphezulu zokuhlushwa ukotini, utamatisi ocutshungulwayo, upelepele nezinye izitshalo. Ngemva kokumuncwa amaqabunga ezitshalo, ingakhuthaza ukuchithwa kwamaqabunga ekuqaleni, okuwusizo ekuvuneni ngomshini. ; Isetshenziswa ngaphansi kwezimo eziphansi zokuhlushwa, inomsebenzi we-cytokinin futhi ingasetshenziswa kuma-apula, amapheya, amapentshisi, ama-cherry, amakhabe, amakhabe nezinye izitshalo ukwandisa izinga lokumisa izithelo, ukukhuthaza ukukhuliswa kwezithelo, nokwandisa isivuno kanye nekhwalithi.

I-Brassinolide (BR) ihlukile kwezinye izilawuli zokukhula kwezitshalo ngendlela yayo eyodwa eqondise ekukhuthazeni isivuno kanye nokwenza ngcono ikhwalithi. Isibonelo, ayinayo nje kuphela imisebenzi ye-physiological ye-auxin ne-cytokinin, kodwa futhi inamandla okwandisa i-photosynthesis nokulawula ukusatshalaliswa kwezakhi, ikhuthaze ukuthuthwa kwama-carbohydrate kusuka esiqwini namaqabunga kuya okusanhlamvu, ukuthuthukisa ukumelana kwezitshalo ezicini ezingezinhle zangaphandle, futhi ukukhuthaza ukukhula kwezingxenye ezibuthakathaka zesitshalo. Ngakho-ke, inokusebenziseka okubanzi kakhulu nokusebenziseka.

I-DA-6 (i-Diethyl aminoethyl hexanoate) isilawuli sokukhula kwesitshalo esinamandla aphezulu esinobubanzi obubanzi kanye nemiphumela ephumelelayo. Ingakhuphula umsebenzi we-plant peroxidase kanye ne-nitrate reductase, ikhulise okuqukethwe kwe-chlorophyll, isheshise i-photosynthesis, ikhuthaze ukuhlukana nokwelulwa kwamangqamuzana ezitshalo, ikhuthaze ukuthuthukiswa kwezinhlelo zezimpande, futhi ilawule ibhalansi yezakhi emzimbeni.

Impuphu yezimpande iyisilawuli sokukhula kwesitshalo esikhuthaza ukukhula kwezimpande zezitshalo.

Umsebenzi wayo oyinhloko uwukukhuthaza ukumila kwezitshalo, ukusheshisa izinga lokukhula kwezimpande zezitshalo, nokuthuthukisa ukumelana nokucindezeleka kwesitshalo. Ngesikhathi esifanayo, i-rooting powder nayo iyasiza ekwenzeni inhlabathi isebenze, ekugcineni umswakama wenhlabathi, futhi ikhuthaze ukumuncwa kwezakhi.
