Izilawuli zokukhula kwezityalo zinokuchaphazela izigaba ezininzi zokukhula nophuhliso lwezityalo.

Kwimveliso yangempela, abalawuli bokukhula kwezityalo badlala indima ethile.

Kubandakanya ukuveliswa kwe-callus, ukusasazwa ngokukhawuleza kunye nokukhutshwa kwetyhefu, ukukhuthaza ukuntshula kwembewu, ukulawulwa kokuvuthwa kwembewu, ukukhuthaza ukukhula kweengcambu, ukulawula ukukhula, ukulawula uhlobo lwesityalo, ukulawula ukwahlulahluko kwentyatyambo, ukulawula indalo yeentyatyambo, ukuvelisa iziqhamo ezingenambewu, 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.Umzekelo, ukusetyenziswa kwezilawuli ze-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 zasemasimini, 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, imoba, icuba, imithi yeti, njl.

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