Abstract
Starenje zrna pšenice je prirodan proces, pri kojem se u zrnu kumulativno nakupljaju kemijske i biokemijske promjene biomolekula, što rezultira gubitkom vijabilnosti i sposobnosti klijanja, te krajnje, smrću zrna. Ovim istraživanjem se pokušalo ustanoviti dolazi li tijekom starenja tri sorte krušnih pšenice pri četiri različita uvjeta skladištenja do promjena u količini ekstraktibilnih proteina te specifičnoj aktivnosti aspartatne proteaze. Rezultati pokazuju nepromjenjivost količine ekstraktibilnih proteina i aktivnosti aspartatne proteaze tijekom godine dana starenja pri svim uvjetima. Tijekom istraživanja uočena je zaraza žitnim žiškom zrnjevlja jedne od ispitivanih sorti, te se pokušalo ustanoviti kako se zaraza žitnim žiškom odražava na aktivnost aspartatne proteaze i udio ekstraktibilnih proteina, a u svrhu pronalaska mogućeg indikatora vizualno "nevidljive" zaraze. Ustanovljene su značajne razlike u aktivnosti aspartatne proteaze između zdravih i zaraženih zrna, te bi aspartatna proteaza mogla poslužiti kao indikator zaraze.
Abstract (english)
Ageing of wheat seeds is a natural process, characterized by the cumulative accumulation of chemical and biochemical changes of seeds biomolecules, which leads to theloss of seed viability, germination ability, and consequently to the seed death. In this research, we have examined changes in proteins extraction and aspartate protease activity of three wheat varieties, aged at four different storage conditions. The results showed that ageing of wheat seeds for one year, at different storage conditions, didn't make changes to protein extractability, or in aspartate protease activity. During seed ageing, in one of the examined varieties, granary weevil infestation occurred. The influence of granary weevil infestation on seeds protein extractability and aspartate protease activity, were therefore examined. Analysis revealed significant differences in aspartate protease activity between non-infested and infested wheat seeds. It would seem that aspartate protease activity could be used as a possible indicator of wheat seeds infestation, by granary weevil.
