Abstract: -Availability of basic information on weed biology is an essential tool for designing integrated management programs for agricultural systems. Thus, this study was carried out in order to calculate the base temperature (Tb) of southern sandbur (Cenchrus echinatus), as well as fit the initial growth and development of the species to accumulated thermal units (growing degree days -GDD). For that purpose, experimental populations were sown six times in summer/autumn conditions (decreasing photoperiod) and six tim… Show more

“…The phenology evaluated in the five experiments was used to estimate the base temperature (Tb) of C. bonariensis, according to the method adapted from Machado et al (2014). Tb is the minimum temperature for the growth of a certain species, below which growth ceases or is greatly reduced.…”

“…The accumulated phenology of C. bonariensis was then fitted to GDD through the linear regression model: y = ax, according to Machado et al (2014), in which y is the estimate of the development of C. bonariensis according to the phenological scale (Hess et al, 1997); x are the accumulated heating units; and a is a parameter of the model.…”
