A simulation model of Avena fatua L. (wild-oat) growth and development. uri icon

abstract

  • An eco-physiological simulation model of the growth and development of A vena fatua was parameterised and tested. The model simulates growth of A. fatua, in kg dry matter ha-1 day-1, from sowing to maturity as a function of irradiance, temperature and various species characteristics. Parameter values were derived from the literature and from field experiments, including both autumn and spring sowings of A. fatua over three years at two sites in southern England. With two exceptions, a single set of parameter values was sufficient to accurately simulate the emergence, growth, and development of both autumn and spring cohorts over all years and sites. The two exceptions were the result of differences between autumn and spring cohorts of A. fatua in the rate of early leaf area growth and in the relationship between specific leaf area and developmental stage.
