I-6-Benzylaminopurine (6-BA) isilawuli sokukhula kwesitshalo sohlobo lwe-cytokinin esidlala indima enhle ekumisweni kwezithelo ezihlahleni zezithelo. Indlela ewumongo yokusebenza kwe-6-BA ukukhulisa izinga lokumiswa kwezithelo ngokukhuthaza ukuhlukana kwamaseli kanye nokulawula izinga lamahomoni endogenous ezitshalweni.
Ngokukhethekile, ukusetshenziswa kwe-6-BA ngesikhathi sokuqhakaza kanye nezigaba zezithelo ezincane zezihlahla zezithelo kungakhuthaza kakhulu ukunwetshwa kweshubhu lempova nokuhluma kwempova, kuqinisekise ukuvundiswa okushelelayo kanye nokunciphisa ukwehla kwembali.
Ngesikhathi esifanayo, i-6-BA ingavimbela ukubola kwe-chlorophyll, ibambezele ukukhula kweqabunga, futhi ihambise imisoco efana nama-amino acid kanye nosawoti we-inorganic kuya esithelweni, inikeze imisoco eyanele yokukhula kwezithelo ezincane kanye nokunciphisa ukwehla kwezithelo zomzimba.
Isibonelo, ezihlahleni ze-citrus ne-apula, ukufafaza i-6-BA ngemva kokuqhakaza kungakhuphula ngempumelelo izinga lokumisa isithelo, ngokunyuka okumaphakathi kwesilinganiso sekhwalithi ephezulu yezithelo ezingama-27%.
Kubalulekile ukuqaphela ukuthi isikhathi nokugxila kwesicelo se-6-BA kubalulekile.
Ngokuvamile, ukufafaza kokuqala kufanele kuqale ezinsukwini ezingu-7-10 ngemva kokuqhakaza (lapho isithelo silingana nobhontshisi wesoya), kulandele ukufutha okwesibili ngemva kwezinsuku eziyi-10-15. Gxila kwisifutho esihlangeni sesithelo nasesithelweni esincane ukuvimbela ukungalingani kwesithelo noma isithelo esikhubazekile.
Ngaphezu kwalokho, i-6-BA ivame ukusetshenziswa ngokuhambisana ne-gibberellic acid nezinye izithako ukuthuthukisa ukunwetshwa kwezithelo. Kodwa-ke, akufanele isetshenziswe yodwa ngemva kwenkathi yesibili yokuwa kwesithelo ukuze kugwenywe ukushintsha umbala wezithelo noma ukukhuthaza ukukhula kwehlumela lasehlobo ngokweqile.
