چکیده

A thermal time (TT) model was developed to simulate field emergence of two weed species (flixweed and wild oat) in winter rapeseed. Practical predictive weed emergence models can provide information about timing of weed emergence. Non-linear regression models are usually able to accurately predict field emergence under specific environmental conditions. In the present study, cumulative seedling emergence in response to TT was described by the Weibull, Logistic, Gompertz, Sigmoid and Chapman functions. Some criteria were used to describe the goodness of fit of the models. These criteria includ coefficient of determination (r2adj), root mean square of error (RMSE) and Akaike index (AIC). In both species (Descurainia sophia: RMSE= 3.65, r2adj=0.97, AIC=88.87; Avena fatua: RMSE= 2.59, r2adj=0.99, AIC=45.83) the seedling emergence flushes were well described with the Weibull four-parameter function. To start emergence after sowing and to reach maximum emergence, lower TT requirements were observed in A. fatua than in D. sophia. Seedling emergence increased steadily and reached from 50% to 90% of total emergence at 315 and 543 TT, respectively for D. sophia and 70 and 286 TT, respectively for A. fatua.
