AB  - Two maize hybrids with a different ability to maintain seed germination were examined during the course of accelerated aging (AA). Initially, the similar seed reduction potential of the GSSG/2GSH half-cell increased in H1 (dent hybrid) without influencing the seed germination ability up to the 6th day of AA, while in H2 (sweet corn hybrid), it was not changed up to the 6th day of AA but with a significant later loss of seed germination ability. During the AA course, the amount of free thiol decreased in H1 and increased in H2. Irrespective of the continual increase of the differential Gibbs energy during AA, the characteristics of the examined hybrids are possibly connected to the different metabolic pathways of the seeds: H1 is characterized by higher entropy and positive enthalpy values, while H2 had negative entropy values and a decreasing trend of enthalpy, indicating a shift of the system from a relatively ordered to a disordered state. The different types of nanomolecular switches, resulting in a faster decrease of GSH in the H2 than in the H1 hybrids, indicate that a combination of the GSSG/2GSH half-cell potential and thermodynamics could be a useful tool to quantify plant stress.
AB  - Proučavano je ubrzano starenje semena dva hibrida kukuruza koja imaju drugačiju sposobnost očuvanja klijavosti. Sličan početni redukcioni potencijal GSSG/2GSH para je kod H1(zuban) rastao bez uticaja na sposobnost klijanja do šestog dana ubrzanog starenja, dok se kod H2 (šećerac) nije menjao do šestog dana starenja, uz kasniji značajan pad klijavosti. Količina PSH se smanjivala kod H1, dok je rasla kod H2 tokom tretmana starenja. Bez obzira na kontinuiran pad slobodne energije tokom ubrzanog starenja, osobine semena ispitivanih hibrida su možda bile vezane za drugačije metaboličke puteve: H1 karakteriše visoka entropija i pozitivne vrednosti entalpije, dok je za H2 karakteristična relativno niska entropija, uz negativne vrednosti entalpije, ukazujući na pomeranje sistema iz relativno uređenog u neuređeno stanje. Drugačiji tipovi nanomolekulskih prekidača, utičući na brži pad GSH kod H2 u odnosu na H1, ističu da se kombinacija GSSG/2GSH ćelijskog potencijala i termodinamike mogu koristiti pri kvantifikaciji biljnog stresa.

AB  - The difference in the growth of maize seedlings originating from seeds injured by accelerated ageing, as well as those altered by restoring with low 2,4-D (2,4-dichlorophenoxyacetic acid) concentrations was examined, from the point of view of free energy and redox potential. The ageing decreased germination ability, the seedling growth and free energy, with no remarkable influence on the redox capacity. Meanwhile, the 2,4-D treatment increased the germination percentage and the seedling growth, by better energy utilisation, with shifting of the redox balance to a reducing environment. From this point of view, the free energy and the redox potential are useful tools for the determination of biological vitality.
AB  - Ispitivana je razlika u rastu klijanaca poreklom iz semena koje je bilo izloženo tretmanu ubrzanog starenja, kao i semena koje je potom bilo izloženo regenerativnom uticaju niskih koncentracija 2,4-D (2,4-dihlorofenoksisirćetne kiseline) i to iz ugla slobodne energije i redoks potencijala. Starenje je smanjilo sposobnost klijanja semena, rast klijanaca i njihovu slobodnu energiju, bez znatnog uticaja na redoks potencijal. Sa druge strane, 2,4-D je uticao na bolje iskorišćenje energije i pomeranje redoks ravnoteže ka redukovanoj sredini, povećavajući klijavost i rast klijanca. Sa ove tačke gledišta, slobodna energija i redoks potencijal mogu biti korisni pri određivanju biološke vitalnosti.

AB  - A trial with four maize inbred lines with the ability to have different durations of seed germination in the course of the accelerated ageing (AA) treatment was set up. Changes of the content of total, reduced and oxidized glutathione (expressed as monomers) were observed in the seeds and seedlings before and after the treatment. For the first time, changes of glutathione in whole seedlings, as well as in the rest of the seed, were analyzed. It was noticed that maize in breds with a smaller decrease of the total glutathione but with an increase of the oxidized form had the ability of prolonged germination. In the control seed- lings, the amount of total glutathione was lower than in the treated ones. Maize seeds which lost germination faster had greater losses of total glutathione with an increased content of the oxidized form in seedlings. The ability of prolonged germination together with the possibility of glutathione synthesis in seedlings are genotypic traits.

Kod njihovih klijanaca došlo je do povećanja sadržaja ukupnog glutationa u odnosu na kontrolne klijance. Seme kukuruza koje brže gubi klijavost imalo je veće gubitke ukupnog glutationa, uz veći sadržaj oksidovanog oblika kod formiranih klijanaca. Dužina očuvanja klijavosti, kao i sinteza glutationa kod klijanaca je genotipska osobina.
