ABSTRACT

Temperature and weed interference often occur simultaneously during the life cycle of wheat. Laboratory investigation was carried out to evaluate the combined effect of temperature and annual ryegrass seedlings interference on wheat seedlings at Agronomy laboratory, Charles Sturt University, Wagga Wagga, NSW 2650, Australia, during 2013. Seedlings of both species were grown simultaneously under two different temperature cycles (i) light/dark for 12/12 h at 20℃/15℃ and (ii) light/dark for 12/12 h at 25℃/15℃. To evaluate wheat interference, two wheat densities e.g. 10 and 20 seedlings/medium were used against 10 seedlings of ryegrass. The results demonstrate that the high temperature cycle increased the seedling growth of both wheat and ryegrass. The root growth and seedling biomass of ryegrass increased dramatically at high temperature even under high interference of wheat. These preliminary outcomes indicate that ryegrass has the ability to persist under both high temperature and crop interference conditions. Thereby, such growth profile of ryegrass will may lead to become widespread weed flora under future elevated temperature climatic condition.
