Abstract
The two herbicides and their combined treatment influenced the change of water input in each of 15 investigated maize inbreds. The water volume (ml) fluctuated between 11 to 110% in shoot and 23 to 275% in root, what introduced the change of free energy (G) from -254.6 to -151.6 KJ in shoot and from -248.0 to -172.3 KJ in root. The difference in free, potential energy between non- and treatment (oΔtreatG) was in shoot from 11.1 to 90.2 KJ and in root from 16.8 to 75.7 KJ. Further, the lower magnitude of oΔtreatG amplitude between root and shoot implicated the tolerance of genotypes to applied herbicides. The energy, spent in biosynthesis of 1mg dry substance was amounted from 75.6 to 16.8 KJ mg-1; the applied herbicide treatments assembled the group of genotypes with lowered necessity of this energy, what has the positive implications in the sense of thermodynamics.
Primena dva herbicida i njihove kombinacje kod klijanaca 15 samooplodnih linija kukuruza uticala je na primenjenu apsorpciju vode. Zapremina vode (ml) je varirala između 11 i 100% u izdanku i 23 i 275% u korenu, što utiče na promenu slobodne energije (G) od 254.6 do -151.6 KJ u izdanku i od -248.0 to -172.3 KJ u korenu. Razlika u slobodnoj energiji između netretiranih i tretiranih biljaka (oΔtreatG) iznosila je u izdanku od 11.1 do 90.2 KJ i u korenu od 16.8 do 75.7 KJ. Takođe manja magnituda oΔtreatG amplitude između korena i izdanka može da ukaže na tolerantnost genotipova prema primenjenom herbicidu. Energija, utrošena za sintezu 1 mg suve supstance je iznosila 75.6 do 16.8 KJ mg-1. Primenjeni herbicidi su istakli grupu genotipova koja je imala manje energetske potrebe za procese biosinteze, što predstavlja pozitivnu tendenciju, sa termodinamičke tačke gledišta.
