Fizičke osobine i ponašanje semena kukuruza (Zea mays L.) - pri pritisnom opterećenju
Univerzitet u Novom Sadu, Poljoprivredni fakultet

Sažetak

Cilj ovih istraživanja je prikupljanje podataka o fizičkim i mehaničkim osobinama šest hibrida kukuruza domaće selekcije. Jedan od njih je polu tvrdunac, dok su ostali zubani. Srednje vrednosti dužine, širine i visine pojedinačnih zrna su dobijeni merenjima na uzorku od 90 semena, a zatim su izračunati srednji geometrijski prečnik, površina pojedinačnog zrna, kao i srednja sferičnost. Nasipna i sopstvena gustina, masa 1000 zrna i koeficijent trenja po metalnoj podlozi su takođe mereni za sve hibride pri jednoj vrednosti vlažnosti zrna. Ustanovljeno je da su najduža zrna bila kod ZP 677 hibrida i to u rasponu od 10,51-11,50 mm. Najveća širina semena je konstatovana za zrna ZP 684 hibrida (7,51-8,50 mm) i ZP 677 (6,51-7,25 mm), dok je najveća debljina uočena kod semena ZP 434 (7,51-8,50 mm) i kod hibrida ZP 677 (6,51-7,25 mm). Srednji geometrijski prečnici su 7,18; 7,15; 6,91 i 6,72 mm izmereni kod hibrida NS 4015, ZP 644, NS 640 i ZP 677, respektivno. Najveća vrednost sferičnosti je konstatovana kod ZP 684 semana (0,75), a zatim slede hibridi NS 640 (0,71), dok hibridi NS 6010 i ZP 677 imaju najniže vrednosti sferičnosti od 0,6. Nasipna gustina semena kukuruza je 784,75 kg/m3 (ZP 677) i 779,58 kg/m3 do 633,56 kg/m3 (NS 6010), dok su vrednosti sopstvene gustine u dijapazonu od 1176,63 kg/m3 (ZP 677) i 1175,65 kg/m3 (NS 640) do 900,94 kg/m3 (NS 6010). Linearni model zavisnosti sekantnog modula elastičnosti od vlažnosti zrna kukuruza je ustanovljen za sve ZP hibride sa visokim vrednostima koeficijenta regresije. Slična zavisnost je ustanovljena i za NS hibride, ali sa nižim vrednostima ovog koeficijenta.
