چکیده انگلیسی
Annual ryegrass is one of the most serious, costly weeds of winter cropping systems in Australia. To determine whether its competition-mediated plant defence mechanisms effect on wheat grain quality, wheat (cv. Yitpi) and annual ryegrass were grown under two levels of CO2 (400â¯ppm; (a[CO2]) vs 700â¯ppm; (e[CO2]), two levels of water (well-watered vs drought) and two types of competition (wheat only; (W), and wheatâ¯Ãâ¯annual ryegrass; (Wâ¯Ãâ¯R) with four replicates. The competitionâ¯Ãâ¯[CO2] interaction had a significant effect on wheat grain protein content, where it was increased in Wâ¯Ãâ¯R under both e[CO2] (+17%) and a[CO2] (+21%). Grain yield, total grain reducing power and phenolic content were significantly affected by [CO2]â¯Ãâ¯droughtâ¯Ãâ¯competition. In a summary, annual ryegrass competition significantly altered the wheat grain quality under both [CO2] levels (depending on the soil water level), while also decreasing the grain yield.
