Izilawuli zokukhula kwezityalo zinokuchaphazela izigaba ezininzi zokukhula nophuhliso lwezityalo.

Kwimveliso yangempela, abalawuli bokukhula kwezityalo badlala indima ethile.

Kubandakanya ukuveliswa kwe-callus, ukusasazwa ngokukhawuleza kunye nokususwa kwetyhefu, ukukhuthaza ukuntshula kwembewu, ukulawulwa kokungalali kwembewu, ukukhuthaza ukukhula kweengcambu, ukulawula ukukhula, ukulawula uhlobo lwesityalo, ukulawula ukwahluka kwentyatyambo, ukulawula indalo yeentyatyambo, ukuvelisa iziqhamo ezingenazimbewu, ukugcina iintyatyambo neziqhamo, ezibhityileyo. iintyatyambo kunye neziqhamo, ukulawula ukukhula kweziqhamo, ukuthintela ukuqhekeka kweziqhamo, ukuqinisa izithole kunye nezithole, ukukhusela indawo yokuhlala, ukuphucula ukunyanzeliswa koxinzelelo, kunye nokuphucula umgangatho wezityalo, ukwandisa isivuno, ukugcinwa kunye nokugcinwa, njl.

Isiphumo sokusetyenziswa kwabalawuli bokukhula kwezityalo sihambelana neteknoloji yesicelo esithile.Ngokomzekelo, ukusetyenziswa kwabalawuli be-auxin kwiindawo eziphantsi kunokukhuthaza ukukhula kwezityalo, ngelixa ukugxila okuphezulu kunokuthintela ukukhula kwezityalo.

Abalawuli bokukhula kwezityalo banoluhlu olubanzi lwezicelo, ezinokuthi zohlulwe zibe ziindawo ezi-6 zilandelayo:

1. Igalelwa kwizityalo zasentsimini, njengerayisi, ingqolowa, umbona, udlwengulo, indongomane, iimbotyi zesoya, ibhatata, umqhaphu kunye netapile.

2. Ifakwe kwimifuno, efana ne-melon, iimbotyi, iklabishi, iklabishi, i-fungi, iziqhamo ze-solanaceous, i-anyanisi kunye negalikhi, imifuno yeengcambu, imifuno eluhlaza eluhlaza, njl.

3. Isetyenziswe kwimithi yeziqhamo, njengama-apile, i-cherries, iidiliya, iibhanana, i-citrus, i-ginkgo, i-peach, ipere, njl.

4. Isetyenziswe kumahlathi, njengefir, pine, eucalyptus, camellia, poplar, rubber tree, njl.

5. Isetyenziswe kwizityalo ezikhethekileyo, ezifana nezityalo ezinevumba elimnandi, izityalo zonyango, amazimba aswiti, i-sugar beet, umoba, icuba, imithi yeti, njl.

6. Isetyenziswe kwizityalo zokuhombisa, ezifana neentyatyambo zemifuno, i-succulents, izityalo zemithi, njl.
