I-6-Benzylaminopurine (i-6-BA) yi-cytokinin-uhlobo lokulawula ukukhula kwesityalo esidlala indima efanelekileyo ekumiseni iziqhamo kwimithi yeziqhamo. Undoqo wokusebenza kwe-6-BA kukunyusa izinga lokumisela iziqhamo ngokukhuthaza ukwahlukana kweeseli kunye nokulawula inqanaba leehomoni ezingapheliyo kwizityalo.
Ngokukodwa, ukusetyenziswa kwe-6-BA ngexesha leentyantyambo kunye nezigaba zeziqhamo ezincinci zemithi yeziqhamo kunokukhuthaza kakhulu ukwanda kwetyhubhu ye-pollen kunye nokuntshula kwe-pollen, ukuqinisekisa ukuchumisa okugudileyo kunye nokunciphisa ukuhla kweentyatyambo.
Ngaxeshanye, i-6-BA inokunqanda ukubola kweklorofili, ilibazise ukuvela kwegqabi, kunye nokuthutha izondlo ezifana ne-amino acids kunye neetyuwa ezingaphiliyo ukuya kwisiqhamo, ukubonelela ngezondlo ezaneleyo zokuphuhliswa kweziqhamo ezincinci kunye nokunciphisa ukuhla kweziqhamo zomzimba.
Ngokomzekelo, kwimithi ye-citrus kunye ne-apula, ukutshiza i-6-BA emva kweentyatyambo kunokunyusa ngokufanelekileyo izinga lokumisela iziqhamo, kunye nokunyuka okuphakathi kwizinga eliphezulu leziqhamo ze-27%.
Kubalulekile ukuqaphela ukuba ixesha kunye nogxininiso lwesicelo se-6-BA lubalulekile.
Ngokuqhelekileyo, ukutshiza kokuqala kufuneka kuqale kwiintsuku ezisi-7-10 emva kokutyatyamba (xa isiqhamo silingana nobukhulu bembotyi yesoya), kulandele ukutshiza okwesibini emva kweentsuku eziyi-10-15. Gxininisa kwisitshizi kwisiqu sesiqhamo kunye nesiqhamo esincinci ukunqanda ukumila kwesiqhamo esingalinganiyo okanye isiqhamo esonakeleyo.
Ukongeza, i-6-BA ihlala isetyenziswa ngokudibeneyo ne-gibberellic acid kunye nezinye izithako zokwandisa ukwanda kweziqhamo. Nangona kunjalo, akufunekanga isetyenziswe yodwa emva kwexesha lesibini lokuthotywa kweziqhamo ukunqanda ukuchaphazela ukuguquka kombala wesiqhamo okanye ukukhuthaza ukukhula okugqithisileyo kwehlumela lasehlotyeni.
