Technological characteristics and quality of seed of freefertilized nd hybrid oil pumpkin sorts

Abstract

The technico-technological and chemical characteristics of seed of 8 free-fertilized and hybrid sorts of oil pumpkin seed with and without hull and two commercial samples of oil pumpkin were investigated. Liter mass and mass of 1000 grains were determined and the percentage of hull in seed samples with hull. The chemical composition was determined investigating the content of moisture, oil, proteins, mineral matter, fiber and total carbohydrates. Regarding the technico-technological characteristics, no significant differences between seeds of free-fertilized and F1 hybrids of oil pumpkih hull-less seed and seed with hull were found. The self-fertilized sorts and F1 hybrids of oil pumpkin, both hull-less and seed with hull, are characterized by high oil content, in the range of 43,27 to 54,78%, calculated on dry matter. The protein content was also high, from 34,97 to 36,61%, on dry matter.

Ispitivane su tehničko-tehnološke i hemijske karakteristike semena 8 slobodnooplodnih i hibridnih sorti uljane tikve golice i sa ljuskom i dva komercijalna uzorka uljanih tikvi. Od tehničko-tehnoloških karakteristika semena određene su litarska masa, masa 1000 semena i određen je procenat ljuske kod uzoraka semena sa ljuskom. Hemijski sastav semena određen je ispitivanjem sadržaja vlage, ulja, proteina, mineralnih materija, celuloze i ukupnih ugljenih hidrata. U pogledu tehničko-tehnoloških karakteristika nisu postojale značajne razlike između semena slobodnooplodnih i F1 hibrida uljanih tikvi golica i sa ljuskom, kao ni komercijalnih uzoraka, što ukazuje da poreklo semena nije imalo uticaja na ove karakteristike. Samooplodne sorte i F1 hibridi uljanih tikvi sa semenom golica i semenom sa ljuskom, odlikovale su se visokim sadržajem ulja koji se kretao od 43,27do 54,78% računato na suvu materiju, a karakterističan je bio i visok sadržaj proteina koji se kretao od 34,97 do 36,61%, računato na suvu materiju.
