Bomvu, orenji, tyheli, ocher ... Uhlobo lwe chromatic indalo ekwindla Isinika imifanekiso eyahlukileyo, eyahlukileyo yemibala kunye neetoni ezibonakala ngathi ziyakudibanisa kumzobo ophindwe ngokutsha okanye kwifoto.
Los imithi ekwindla Banombala opheleleyo wombala kumagqabi abo, ngaphambili aluhlaza. Kodwa… Kutheni betshintsha umbala?
La imibala eyahlukeneyo yemithi ekwindla inxulumene nexesha lemitha yelanga. Ukukhanya kwelanga kuyafuneka ukuze kutyalwe ukuze kuveliswe chlorophyll (ebanika umbala wazo oluhlaza). I-chlorophyll, nayo, ibalulekile kwi-photosynthesis, oko kukuthi, inkqubo ethi iklorofili kumagqabi iguqule amanzi kunye nekhabhon dayoksayidi ibe kukutya.
Ngexesha lasebusika, akukho langa laneleyo lomthi ukugcina inkqubo yalo ifotosinthesis ugcwele, ke umthi uyahamba ulele kwaye ulinde intwasahlobo ukuba ibuye kwakhona.
Ukuveliswa kweklorophyll kuyancipha okanye kuyeke kwaye kulapho ezinye ii-pigment zamagqabi ezazikhona ngaphambili, kodwa zazifihlwe yiklorofili eluhlaza eluhlaza, ziqala ukuvela.
Veza ifayile ye- carotenoids, eziyimfuneko zokudlulisa amandla elanga, kwaye zinike amagqabi ngombala otyheli, ocher, kunye nombala weorenji. Ngaphandle koko, i anthocyanin, engekhoyo kuzo zonke iintlobo, ikhusela imithi kwimitha ye-ultraviolet kwaye ivelisa ithoni ebomvu, eluhlaza okwesibhakabhaka kunye nemfusa.
Imibala yeli xesha lonyaka iba namandla ngakumbi xa iintsuku zasekwindla zinelanga kwaye ubusuku bubanda kodwa ubushushu abwehli ngaphantsi kweqondo. Ukuba oku akwenzeki, amagqabi ayafa, ajike abe mdaka kwaye awele emhlabeni, apho inkqubo yokubola ibanika imibala emitsha.
