I-CIE Chemical iyakuthokozela ukusebenza ucwaningo futhi ikhiqize amakhemikhali akhethekile athuthukisa impilo yezitshalo namandla. Sibhekana nekhemikhali eyodwa enegama lezinhlobo: i-1-naphthylacetic acid noma i-NAA ngamafuphi. Lokho kuyikhemikhali yezolimo enenzuzo kakhulu njengoba isiza ekuthuthukiseni indlela izitshalo ezikhula ngayo.
NAAisilawuli sokukhula kwezitshalo (NAA)Ihomoni yezitshalo Amahomoni ayizithunywa ngaphakathi kwezitshalo ezitshela ukuthi yenze izinto. I-NAA isetshenziswa abalimi nabalimi ukukhuthaza ukukhula kwezitshalo okunempilo. Le khemikhali ihlanganiswa ukuze ilingise ihomoni yemvelo kakade esitshalweni. I-NAA inenzuzo ezigabeni ezihlukahlukene zokukhula kwezitshalo, okuhlanganisa ukwakha izimpande, ukukhiqizwa kwezithelo, nokuqhakaza.
I-NAA inezici ezimbalwa ezinhle eziyenza ibe wusizo ezitshalweni. Inzuzo eyinhloko yokusebenzisa i-NAA ukwakheka kwezimpande okuthuthukisiwe. Izimpande eziqinile zingangena kude emhlabathini zifuna amanzi nezakhamzimba ezidingekayo ukuze ube nempilo enhle. Izimpande ezijulile zisiza lesi sitshalo ukuba sikhule sibe namahlamvu amaningi. I-NAA iphinde isetshenziselwe ukukhulisa nokwenza ngcono ukunambitheka kwezinye izithelo ezinjengotamatisi, amagilebhisi, njll.
I-NAA ingenza nama-apula anosayizi ongaguquki. Isibonelo, i-NAA ibe isisetshenziswa ekuqaleni kwenkathi yokukhula lapho ama-apula namapheya ekhula ukuze enze kube nokufana ngosayizi nokuma. Futhi lokhu kubalulekile kubalimi ngoba abathengi bangase bathenge izithelo zekhwalithi ephezulu ezibonakala zizinhle futhi zifana ngosayizi uma beya emakethe.
I-Indole-3-acetic acid yilokho esivame ukubhekisela kukho njenge-NAA, futhi iyi-hormone yezitshalo ethatha ingxenye enkulu kakhulu ekukhuleni nasekuthuthukisweni kwezitshalo. Njengoba sishilo ngaphambili, izimpande eziqinile zizokhula futhi zizogqugquzela ukukhiqizwa kwezimpande ezengeziwe. Lokhu kubaluleke ngempela njengoba izimpande zezitshalo zidinga ukuba nempilo ukuze zihlale zimanzi ngokuphuza amanzi futhi zimunce imisoco emhlabathini wazo. Futhi, ngaphandle kwezimpande ezijulile, izitshalo zingase ziphile kancane.
Ucwaningo olusha lwembula ukusetshenziswa okujabulisa kakhulu kwe-NAA ezitshalweni kunalokho obekuqondwa ngaphambilini. Ngokwesibonelo, abacwaningi bathola ukuthi i-NAA ingase ivikele izitshalo kusikhunta esiyingozi—okuyizinto eziphilayo ezincane kakhulu ezikwazi ukulimaza izitshalo nokudanga izifo. Ngakho-ke i-NAA ingaba i-ejenti yokuvimbela i-biogenic yezitshalo.
I-NAA iphinde yahlolisiswa ukuze ikwazi ukumelana nezingcindezi ze-abiotic ezifana nesomiso kanye nosawoti ezitshalweni. Nakuba lezi zimo zingase zidale izitshalo, i-NAA ingase izisize zibhekane nazo. Nakuba sisafunda ukungena nokuphuma kwe-Na-Al(SO4)2·12H2O, mhlawumbe sizothola izinto ezinhle kakhulu esingakwenza ngalekhemikhali emgwaqeni.
