Conteúdo: 	Several models are available for sugarcane crop and all of them are based on physiological knowledge translated in mathematical equations coordinated in algorithms. For Brazilian sugarcane, however, there are few studies describing the main physiological characteristics to be included in the models. This paper has a major goal to characterize the physiological parameters controlling growth and development of two of the most important Brazilian sugarcane cultivars, and compare them with NCo376, a well-studied South African cultivar. As results, we found maximum leaf size differed little among Brazilian cultivars, being as large as 796 cm2 for RB72-454 and 733cm2 for SP83-2847. The mean value for the maximum green leaf number per stalk for the cultivars was approximately 9, and the observed biomass accumulation in the millable stalks closely mirrored the accumulation of above-ground biomass for the two cultivars, starting with 9% at 129 DAP to reach a maximum of around 65% after 330 DAP for RB72-454. Specific root length (m g-1) ranged from 16 m g-1 and 22 m g-1 on average from 125 DAP onwards.
