Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 9
Abstract
In order to recognize, identify and determine the relative dominance of weed species distributed in wheat fields of Tabriz county-Iran, a total 118 weed species belonging to 24 plant family were observed. Ermopyrum bonaepartis (Spreng.) Nevski, Acroptilon repens (L.) DC., Cardria Draba (L.) Desv., Chenopodium album L., Polygonum aviculare L., and Convolvulus arvensis L. with relative dominance (RD) index equal 30, 20.2, 19.1, 18.1, 17.5, and 17.5 respectively were dominant weed species. Poaceae, Brassicaceae and Asteraceae with Family Dominance Index (FDI) equal 63.08, 45.54, and 45.46 were dominant plant families observed in wheat fields. A. repens (L.) DC., C. Draba (L.) Desv., C. album L., P. aviculare L., and C. arvensis L. with frequency level 82.2, 75.6, 62.2, 64.4 and 64.4 respectively were the main disturbing weeds prior to harvesting wheat in Tabriz county. Eighty-nine percent of weeds were below average, because they founded below thirty percent of wheat fields. However, nearly four percent of weeds were assertive and distributed in more than sixty percent of wheat fields. So, the revised management procedure about these weeds in different districts of this county is very important.
