A dynamics of seed mass defect and a previous process of the water input during germination was determined by a trial with five soybean cultivars and four sunflower hybrids, following the ISTA Rules. It was noticed that leaching, which led to the mass defect (smDef), was permanent during 8 and 10 days of soybean and sunflower germination, respectively. The two confronted processes, the liquid input and the solid output, could be operable at the level of a thermodynamic parameter of Gibbs free energy (G), i.e. net supplemental free energy (netGspl). Hence, this type of free energy - net supplement, differentiates in two examined plant species (between the first and the last day of germination): soybean in a range from -53.23 to -69.82 J mol-1 seedling-1 and sunflower from -46.35 to -91.94 J mol-1 seedling-1. Furthermore, the daily change of net supplemental energy underlined the three points ingenotypes of both species: after the first, before the last day of germination and in the maxi...mum (-67.50 and -75.25 J mol-1 seedling-1 in soybean, then, -94.97 and -103.79 J mol-1 seedling-1 in sunflower) between the 4th and the 7th day of germination depending on a genotype.
U ovom radu izneta su kvantitativna određivanja dinamike gubitka mase semena tokom klijanja kod pet sorti soje i četiri hibrida suncokreta po ISTA pravilima. Kako je metoda određivanja masenog defekta semena davala i dinamiku usvajanja vode, ta dva podatka prevedena u Gibsovu slobodnu energiju omogućila su operaciju sa dva suprotstavljena procesa: usvajanja tečne i ispuštanja čvrste supstance, koje su oduzimanjem dale neto energiju unetu u sistem seme-klijanac. Pokazalo se da neto, dopunska slobodna energija u opsegu od -53.23 do -69.82 J mol-1 klijanac-1 za soju (od prvog do osmog dana) i od -46.35 do -91.94 J mol-1 klijanac-1 za suncokret (od prvog do desetog dana), daje razliku između dve ispitivane vrste. Dalje, dnevna promena neto, dodatne energije razdvaja genotipove kod obe biljne vrste u tri tačke: posle prvog dana, pre zadnjeg dana i maksimum (-67.50 i -75.25 J mol-1 klijanac-1 za soju, a -94.97 i -103.79 J mol-1 klijanac-1 za suncokret), između četvrtog i sedmog dana, što zav...isi od genotipa.
