Abstract

This experiment was conducted under pot conditions to investigate competitiveness of spring wheat (Triticum aestium, Chamran cultivar) subject to various plant populations of wild oat Avena fatua, using completely randomized design with three replications in 2006 in the greenhouse of Ramin Agricultural and Natural Resources University, Mollasani Khouzestan. The treatments included pure stands of wheat and wild oat at one level (ratios 4: 0 and 0:4), and DENSITY difference ratios wheat and wild oat at seven levels (4:1, 4:2, 4:3, 4:4, 1:4, 2:4 and 3:4). The results showed that RELATIVE CROWDING COEFFICIENT (RCC) of wheat to wild oat and wild oat RCC to the wheat were equal. This indicated that competitive ability of the two plants were similar. While relative grain yield of wheat decreased by increasing RELATIVE LEAF AREA of wild oat. Ability AGGRESSIVITY of wild oat showed that wild oat was more successful in using environmental sources, observed clearly in ratio the 4:4. Moreover mean stem height, mean spikelet number per spike, mean grain number per spike, mean 1000-grain weight, final biomass and grain yield of wheat plant decreased with increasing wild out DENSITY.
