Nazi ezinye zezinto izitshalo ezidinga ngempela. Zidinga inhlabathi eqinile, amanzi amaningi kanye nokukhanya kwelanga ukusiza ukukhula kwazo. Noma kunjalo, ngezinye izikhathi ingxube yalokhu iyodwa akwanele ukubasiza ukuba bahlume okuhle kakhulu. Kulapho amahomoni ezitshalo angena khona. Lawa asebenza njengemithi eyimilingo yamahomoni ezitshalweni, ezivumela ukuthi zikhule ngokukhudlwana nangokushesha kakhulu kunalokho ebezingakwenza. Enye i-hormone enjalo ibizwa ngokuthi i-6-Benzylaminopurine. Igama layo lide futhi liyinkimbinkimbi, kodwa lokhu kunendima ebalulekile ekusizeni izitshalo.
Sekungamashumi eminyaka abalimi bezentengiselwano besebenzisa amakhemikhali athile ukukhuthaza ukukhula kwezitshalo zabo. Lawa makhemikhali ayakwazi ukwenza izitshalo zibe namandla futhi zikhiqize mayelana nokwandisa inani lokudla okukhiqizwayo. Kodwa-ke, i-6-Benzylaminopurine ayifani nalawo makhemikhali. Kuyi-hormone yezitshalo yemvelo, isiza ekukhuleni okungcono nokuqinile kwezitshalo. Ungakucabanga njengokuhlinzeka ngethuluzi elikhethekile ezitshalweni, okwenza zikhule ngokushesha futhi zibe nempilo. Sekuyiminyaka eminingi ososayensi behlola le hormone ukuze baqonde indlela esebenza ngayo ezitshalweni. Manje sebeludlulisele lolo lwazi bashintsha indlela esitshala ngayo izitshalo emapulazini.
Isitshalo sidinga amandla amakhulu ukuze siqale ukukhula lapho siqala ukukhula. Yilapho i-6-Benzylaminopurine kumele ingenele ukuze isize. Kuyasiza ukuthi imbewu ihlume ngokushesha. Imbewu isengamila ngokushesha ngokuphindwe kane uma le hormone ikhona, futhi lokho kusho ukuthi izimpande ziqala ukukhula ngaphambi kwesikhathi. Isistimu yezimpande eqinile, ekhula ngokushesha ibalulekile ukuze isitshalo sithole umsoco namanzi emhlabathini. Lokho kubangela izitshalo ezinempilo kanye nesivuno esikhulu kubalimi.
Isibonelo senkampani esebenzisa i-6-Benzylaminopurine i-CIE Chemical. Ngenxa yalokho, benze inhlanganisela enamandla kakhulu okulula ukuthi abalimi bayisebenzise. Lokho kusho ukuthi abalimi bangasebenzisa le fomula ezitshalweni zabo ukuze izisize zikhule ziqine futhi zisheshe kakhulu. Kuyi-hormone yemvelo, ngakho futhi iphephile emvelweni, futhi ngeke ilimaze inhlabathi noma isitshalo. Okwesikhombisa, ifomula esetshenziswa yi-CIE Chemical ukuqinisekisa ukuthi abalimi bangakhiqiza ukudla okwengeziwe emhlabeni wonke futhi bavune isivuno esingcono.
Laba sosayensi basafunda i-6-Benzylaminopurine ukuze baqonde ngokugcwele umsebenzi wayo futhi basize ekukhuleni kwezitshalo. Bafuna ukwazi ukuthi kusebenza kanjani -- ezingeni lamangqamuzana, kuze kufike emininingwaneni emincane kakhulu. Ngalolu lwazi, bazokwazi ukuqhamuka namafomula ahlukene kuyilapho bethuthukisa nalawo akhona. Konke okutholakele okuhilela le hormone yezitshalo engavamile kuyoqhubeka kusenza sikwazi ukusiza izitshalo ekukhuleni kangcono, sondle inani elikhulu labantu futhi silondoloze indawo yethu yezizukulwane ezizayo.
