Barium concentration in grain of aegilops and triticum species

Abstract

The aim of this study was to evaluate the concentration of barium in grain of various Aegilops and Triticum species with different genomes. The studied species differed significantly with respect to the concentration of barium. The grain of wild diploid Aegilops speltoides, the donor of B genome, contained significantly higher Ba concentration than all other analyzed genotypes. Wild and cultivated tetraploid wheats (Triticum diciccoides, Triticum dicoccon, Triticum turgidum and Triticum durum) had the lowest Ba concentration in grain. The modern cultivated hexaploid varieties presented substantial variation in grain concentration of barium. The highest Ba concentration (3.42 mg/kg) occurred in Serbian winter wheat variety Panonnia.

Cilj ovog istraživanja bio je da se procene koncentracije barijuma u zrnu različitih genotipova Aegilops i Triticum vrsta. Ispitivane vrste su se značajno razlikovale u odnosu na koncentraciju barijuma. Zrno divljeg diplo ida Aegilops speltoides, donator B genoma sadrži znatno veću koncentraciju barijuma nego svi ostali ispitivani genotipovi. Divlja i pitoma tetraploidna pšenica (Triticum diciccoides, Triticum dicoccon, Triticum turgidum i Triticum durum) imala je najnižu koncentraciju barijuma u zrnu. Moderne gajene heksa plo idne sorte po kazale su značajne varijacije u koncentraciji barijuma u zrnu. Najveće koncentracije (3,42 mg/kg) ustanovljene su kod “Panonije”, ozime sorte pšenice proizvedene u Srbiji.
