The presence severity of wild wheat (Triticum boeoticum Boiss) and wild barley (Hordeum spontaneum K. Koch) weeds in the rainfed wheat fields of Lorestan province.
Studies were conducted to specify the presence severity index (PSI) and the infection hotspots of wild wheat (Triticum monococcum subsp. aegilopoides) and wild barley (Hordeum spontaneum) weeds in rainfed wheat fields of Lorestan province, Iran. Data on grass weed species occurrence in rainfed wheat were collected in spring 2014 and 2015 from the 397 rainfed wheat fields throughout Lorestan province. Based on the results, the presence altitude domain for wild barley in rainfed wheat fields of Lorestan was 81.3% more than wild wheat, which demonstrated a higher possibility of wild barley invasion in a broader altitude scope in the region.
