dc.description.abstractThe seed filling is a functional consequence of two parallel processes: increasing of water content (incorporates substances and serves as a reaction medium in seeds) and increasing of dry matter content (by absorption and polymerisation). The increase of seed weight was occurring up to the moment of maximal polymerisation, when seed started to release water to get into a dormant stage. The aim of this experiment was to examine dynamics of free, hygroscopic and constitution water during seed filling in four populations and six ZP hybrids of maize, as well as, their correlation with phytic and inorganic phosphorus, as well as, soluble proteins. The dominant water form present during the seed filling was free water. Decreasing of its content occurred 30 days after pollination, while the period of maximum seed weight maintenance was observed more in hybrids than in populations. Moreover, the period of intensive seed filling was longer hybrids than in populations. The dynamics of hygroscopic water had sinusoidal trend for all genotypes. The drop in the content of free water during seed filling occurred at the same time as the decrease in the content of constitution water. The alterations in contents of free and constitution water were, to a great extent, related to the phytate accumulation and the decrease of soluble proteins. From the point of view of selection, the genotypes, such as the population 216, with low phytate and moisture contents in seeds, could serve as a basis for breeding programmes of genotypes with a greater dry down rate.en
dc.description.abstractNalivanje semena je funkcionalna posledica dva paralelna procesa: povećanja sadržaja vode (unosi supstance za izgradnju semena i služi kao reakcioni medijum) i povećanja sadržaja suve materije (apsorpcijom i polimerizacijom). Navedeni rast mase se dešava do trenutka kada procesi polimerizacije dostignu svoj maksimum i kada seme počne da otpušta vodu da bi prešlo u stanje mirovanja. Cilj ogleda je bio da se ispita dinamika slobodne, higroskopne i konstitucione vode tokom nalivanja semena kod četiri populacije i šest ZP hibrida kukuruza, kao i njihova korelacija sa fitinskim i neorganskim fosforom i rastvorljivim proteinima. Tokom nalivanja semena kukuruza dominantna forma vode je bila slobodna voda. Smanjenje njenog sadržaja je nastupilo već nakon 30 dana od oplodnje, dok je kod hibrida period zadržavanja maksimalne mase semena, tj. period intenzivnijeg nalivanja bio nešto duži u odnosu na populacije. Dinamika higroskopne vode je imala sinusoidni trend koji je bio sličan kod većine genotipova. Paralelno sa padom slobodne vode tokom nalivanja semena kukuruza bio je prisutan i trend pada konstitucione vode. Promene sadržaja slobodne i konstitucione vode su bile u visokom stepenu vezane za nakupljanje fitata i smanjenje solubilnih proteina. S tačke gledišta odabira genotipova koji bi mogli predstavljati bazu za brzo otpuštanje vlage prilikom zrenja semena trebalo bi uzeti u obzir populaciju 216, koja uporedo ima i niži nivo fitata u semenu.sr
