Analysis the parameters of seed quality in ns sunflower hybrid after processing in gravity separator

Abstract

This paper analyzed the processed seed of five sunflower hybrid seed developed at the Institute of Field and Vegetable Crops in Novi Sad before and after processing in gravity separator. The cultivars were Pegaz, Duško, NS Fantazija, Sumo 1 PR and NS Oskar. The analysis was conducted on seed lots processed in 2015 and involved the following parameters: seed purity percentage, 1.000-seed weight, germination energy, germination, seed moisture, number of sclerotinia per 1.000. The results showed that all the parameters of seed quality of sunflower hybrids were better after processing seeds in the gravity separator.

U ovom radu analizirano je seme pet hibrida suncokreta pre i posle dorade na gravitacionom stolu. Hibridi su nastali u Institutu za ratarstvo i povrtarstvo u Novom Sadu i to su: Pegaz, Duško, NS Fantazija, Sumo 1 PR i NS Oskar. Analiza je sprovedena po partijama dorađenog semena u 2015-oj. godini i obuhvatila je sledeće parametre: čistoću semena, masu 1000 semena, energiju klijanja, klijavost, vlažnost semena i broj sklerocija. Rezultati su pokazali da su svi parametri semenskih kvaliteta suncokreta kod svih hibrida bolji posle dorade semena na gravitacionom stolu.
