Prouèavane su komponente prinosa za 2 geneticki divergene sorte pšenice (KG-35265 i<br />
KG-52) gajene u poljskim uslovima zalivanja vodom razlièitog stepena èistoæe<br />
(kontrola=bez zalivanja, voda sa èesme, voda èistih ekosistema, poluzagaðena voda i<br />
zagaðena voda). Reakcija prouèavannih genotipova je ocenjena na osnovu analiziranih<br />
njihovih morfoloških i produktivnih osobina. Efekat zalivanja je analiziran. Takoðe je<br />
analizirana razvijenost i masa korena kod prouèavanih genotipova. Najveæi prinos zrna<br />
dobijen je na varijantama zalivanim vodom sa èesme i vodom iz èistih ekosistema a<br />
najmanji na varijanti bez zalivanja.<br />
EXPRESSION OF WHEAT GENETIC ADAPTABILITY ON<br />
ENVIRONMENTAL CONDITIONS<br />
Yield components of wheat were studied in two genetic divergent cultivars (KG-35265<br />
and KG-52) which grown under irrigation condition. Water was from source with different<br />
degree of purity (control = without, common water, water from pure ecosystem, half<br />
polluted an polluted water). Reaction of investigated genotypes was estimated on the<br />
base of analyzed morphological and productive traits. Effect of water was analyzed. At<br />
the investigated genotypes the mass of root was analyzed, too. The highest value of grain<br />
yield was obtained on variant irrigated by pure water in compare with control.
